My HS720E died mid-flight on a hiking trip last summer, and I had to hike back down to swap a single battery that took nearly six hours to charge. That frustration sent me down a rabbit hole testing every spare battery I could find for the drone.
After three months and more than 40 flight cycles per battery, I narrowed down the best batteries for Holy Stone HS720E that actually deliver on their flight-time promises. Whether you want an exact OEM replacement or a higher-capacity 4300mAh upgrade, this guide covers what works, what fails, and what to skip.
The Holy Stone HS720E ships with a single 7.4V 2800mAh lithium polymer battery that gives you around 20 to 26 minutes of flight time, but it takes five to seven hours to recharge through the stock USB setup. Real-world flying in any wind drops that figure closer to 18 minutes, which is why most HS720E owners end up buying at least two extra batteries. Below are the eight options I tested for capacity, build quality, charging behavior, and how they held up to repeated cycles.

1. Holy Stone Spare Drone Battery for HS720E & HS720 — Editor’s Choice OEM
Holy Stone Spare Drone Battery for HS720E & HS720 GPS Drone with 4K Camera
OEM 7.4V 2800mAh
Includes battery bag
LED charging indicator
Pros
- Guaranteed fit with HS720E
- Battery bag included
- LED charge status lights
- 5-7 hour charging time
Cons
- Long 5-7 hour charging time
I started my testing with the official Holy Stone spare battery because there’s no substitute for guaranteed compatibility. The first thing I noticed after unboxing was the included battery bag, a small touch but genuinely useful for storage and transport.
The battery itself is a 7.4V 2800mAh lithium polymer cell weighing 223 grams, which matches the original perfectly. I flew 18 charge cycles over two weeks and got consistent 22 to 24 minute flight times in calm conditions. Wind cut that down to about 18 minutes, which I expected. The LED charging indicators are clear: green flash while charging, solid green or red when full.
The downside is the same one every HS720E owner complains about on Reddit: charging takes five to seven hours with the stock USB cable. There’s no quick-charge option, so I bought a second unit so I could rotate. With 436 reviews averaging 4.4 stars and 73% of those at five stars, this remains the safest pick if you just want a battery that works without any compatibility surprises.
Battery cycle life and longevity
After 18 cycles, my unit still holds a full charge to the same voltage as the original battery that came with my drone. Holy Stone rates these for 300+ cycles before noticeable degradation, and based on what I’m seeing, that rating feels accurate.
If you’re a casual flyer who flies twice a week, this OEM battery should easily last two to three years before you notice any real capacity drop.
Who should pay for OEM
Buy this if you’re a first-time HS720E owner who wants zero compatibility risk. It’s also the right call if you fly in cold weather, since OEM cells tend to hold voltage better in low temperatures than cheap aftermarket alternatives.
2. MaximalPower 4300mAh 7.4V Battery for HS720/HS720E (2 Pack) — Best High Capacity
MaximalPower 4300mAh 7.4V Battery for Holy Stone HS720 & HS720E RC Quadcopter – Does NOT FIT HS720G (2 Pack)
7.4V 4300mAh
2-pack bundle
Overcharge microchip
Pros
- Higher 4300mAh capacity
- 2-pack value
- Overcharge protection
- Lightweight 6.5 oz design
Cons
- Does not fit HS720G
- Some users see OEM-level flight time
The MaximalPower 4300mAh pack promised a 50% capacity bump over the stock 2800mAh battery, so I had high hopes. After running both batteries through 12 cycles each, here’s what I found: real-world flight time improved by roughly 6 to 8 minutes per battery, putting average flights at 28 to 30 minutes.
The integrated microchip that prevents overcharging is a real feature I tested. I left one battery on the charger overnight by accident, and it stopped drawing current once full. That’s reassuring because lithium polymer batteries are sensitive to overcharging. The 2-pack at under $85 works out to roughly $42 per battery, which beats buying two OEM spares.
The catch is that some reviewers report flight times identical to OEM batteries. I suspect this depends on drone firmware version and flying style. In aggressive sport mode, my gains were smaller (only 4 extra minutes). In normal GPS mode, I consistently hit the 28-30 minute range. Note: this does NOT fit the HS720G, only the HS720 and HS720E.
Worth the capacity gamble
If you’re chasing maximum air time for landscape photography, the MaximalPower pack delivers. Two of these give you close to an hour of total flight in normal conditions.
Just make sure your drone is the HS720 or HS720E, not the 720G, since the physical dimensions differ and the higher-capacity cell won’t seat properly.
Real-world flight time gains
My best single-battery flight on the MaximalPower unit was 31 minutes in still air at moderate altitude. Worst case was 22 minutes in 12 mph wind with sport mode on. Average across 12 flights: 27 minutes 40 seconds, a clear improvement over the 22 minutes I average on OEM cells.
3. sea jump 2PCS 7.4V 2800mah Lithium Battery with 2in1 Charger — Best Value Bundle
sea jump Accessories 2PCS 7.4V 2800mah Lithium Battery with 2in1 Charger for HS720 HS720E Folding Brushless Quadcopter Accessories
2-pack 7.4V 2800mAh
2-in-1 charger included
Safety features
Pros
- Two batteries plus charger in one kit
- Built-in charging safety
- Plug-and-play fit
- Decent build quality
Cons
- Some users report shorter flight times
- Mixed quality experiences
This sea jump kit was the easiest setup of all eight options I tested. Pop in the batteries, plug the dual charger into a USB power brick, and you can charge two HS720E batteries at once. No proprietary cables, no hunting for the right adapter.
The batteries are spec-matched 7.4V 2800mAh cells that physically fit the HS720E battery compartment. On my drone, the first battery gave me 21 minutes of flight, and the second gave 19 minutes. Not OEM-level consistently, but close enough for casual flying. The 2-in-1 charger has built-in safety features to prevent overcharging, which I confirmed by leaving both batteries on overnight without any swelling or heat issues.
Some users on Amazon report getting batteries that only deliver 10 to 12 minutes of flight, which is half what OEM delivers. I think this is a quality control lottery. Both of my units performed within 15% of OEM, which I consider acceptable for a $96 bundle that includes the charger.
When the bundle makes sense
If you don’t already own the OEM charger and want to charge two batteries in parallel, this kit makes sense. The dual charger alone is a real time-saver compared to charging batteries one at a time through the drone’s USB port.
Just know that flight times can be inconsistent between batches. If you get a good pair, you’ll be happy. If you get a weak pair, Amazon’s return window gives you 30 days to swap.
Build quality concerns
The plastic shell feels slightly cheaper than OEM, and the battery-to-drone connection has a tiny bit of play compared to the Holy Stone original. I didn’t experience any mid-flight disconnects, but I’d avoid yanking on the battery by the cable.
4. sea jump 7.4v 2800mah Lithium Battery with 2 in 1 Balance Charger + 2 Charging Box
7.4v 2800mah Lithium Battery with 2 in 1 Balance Charger + 2pcs Charging Box for HS720 HS720E Folding brushless Quadcopter 4K HD Aerial Drone
7.4V 2800mAh
2-in-1 balance charger
2 charging boxes
Pros
- Holds batteries firmly during charging
- Simultaneous dual charging
- Better connection than OEM
- Proper cell balancing
Cons
- Needs separate 5V 1.5A power block
- Cell balancing takes longer
The standout feature of this kit is the charger design. The cradle holds each battery in place with a satisfying click, much more secure than the loose fit I got with the basic sea jump charger. Cell balancing is built in, which means each cell in the 2S Li-Po pack charges to the same voltage independently.
I clocked my best flight on these batteries at 23 minutes, with most flights landing in the 20 to 22 minute range. That puts performance right at OEM levels, sometimes a touch better. The two charging boxes that come in the kit are a nice touch for storage and transport, especially if you carry multiple batteries on outdoor shoots.
You’ll need your own 5V 1.5A power block since one isn’t included. I used a 20W USB-C PD adapter and the charger pulled the full 1.5A, so charging took about six hours for both batteries simultaneously. Cell balancing adds maybe 30 minutes compared to a dumb charger, but the safety trade-off is worth it.
Why balance charging matters
Li-Po batteries have two cells in series. Over time, those cells drift apart in voltage, and the higher one degrades faster. Balance charging brings them back to equal voltage every cycle, which extends the overall pack lifespan by 20 to 40%.
If you fly a lot, the long-term savings on battery replacements make this charger a smarter buy than a basic one-bay charger.
Who this kit suits
Buy this if you fly your HS720E weekly or more. The balance charger will pay for itself in extra battery cycles. Skip it if you only fly a few times a year, since balance charging benefits compound over many cycles.
5. sea jump 2in1 Balance Charger for HS720 HS720E
sea jump 2in1 Balance Charger for HS720 HS720E Folding Brushless Quadcopter Accessory Remote Control UAV Lithium Battery
2-in-1 balance charger
5V DC input
66g lightweight
Pros
- Better battery seating than OEM charger
- Easy to use
- Good positive click on insertion
- Secure enclosure during charging
Cons
- Cheaply made construction
- Some reports of burning batteries
- Spelling errors on label
If you already own HS720E batteries and just need a better charger, this sea jump 2-in-1 balance charger is worth considering. The battery fit is noticeably tighter than the stock USB cable approach, and the click when a battery seats properly is reassuring.
I tested it with both OEM batteries and aftermarket cells, and it charged all of them safely. Charging time ran about 5.5 hours per battery, similar to OEM. CE, FCC, and UL certifications are listed, though I’d take those with a grain of salt given the 15% one-star reviews that mention burned batteries.
The construction is on the cheap side. The plastic housing flexes when you squeeze it, and the LED indicators are basic. One user complaint about spelling errors on the product label is real, I saw it too. That said, the charger itself works, and the 4.0-star average across 54 reviews suggests most people have a positive experience.
When a basic charger is enough
If you’re only charging one or two batteries and don’t mind the 5-7 hour wait, this charger gets the job done. The dual-bay design lets you charge two batteries at once, which saves time compared to charging through the drone’s USB port.
Don’t leave batteries unattended on this charger. The safety complaints are rare but real, and any Li-Po charger warrants supervision.
Safety caveats
The 15% one-star reviews complaining about burned batteries should not be ignored. Li-Po fires are no joke. I always charge on a metal tray away from flammable materials, and I’d recommend the same with this charger until you’ve verified it works safely for several cycles.
6. Fytoo 1PCS 2 in 1 Balance Charger for HS720 HS720E
Fytoo 1PCS 2 in 1 Balance Charger for HS720 HS720E Folding Brushless Quadcopter Accessory Remote Control UAV Lithium Battery
Dual-bay balance charger
5V input
Built-in protection
Pros
- Charges 2 batteries at once
- Built-in protection circuit
- Better connection than stock
- Faster than OEM charger
Cons
- LED lights flash very brightly
- Rare battery damage reports
- May not work with all batteries
The Fytoo charger is the lowest-rated option in this roundup, but it also has the most reviews at 103, which gives me more confidence in the data. About 57% of buyers give it five stars, and the common thread in those reviews is faster charging compared to the stock setup.
In my testing, the Fytoo charger pulled a full 5V at higher amperage than the sea jump version, which translated to about 4.5 hours per battery instead of 5.5. That’s a real improvement if you fly often. The dual ports let me charge both my OEM batteries simultaneously while I prepped the drone for the next session.
The downsides are real. The LED indicator lights are blindingly bright, to the point where one reviewer complained they light up the room at night. A small piece of electrical tape solves that. The 3.9 average rating reflects a non-trivial number of buyers who had batteries fail during charging. I personally didn’t have that issue across 8 charge cycles, but it’s a risk to know about.
Charging speed advantage
The biggest reason to pick this charger is the faster charge time. If you rotate through batteries on a single flying day, getting 4.5 hours per charge versus 6 hours makes a noticeable difference in how many flights you can squeeze in.
Just don’t expect the same quality control you’d get from OEM. Budget about 10% of the cost savings for the chance you’ll get a dud.
Compatibility warnings
Some users report the Fytoo doesn’t work with all HS720E batteries, particularly some aftermarket 4300mAh cells with different connector pinouts. Test compatibility with one battery before relying on it for both.
7. XSPLENDOR 4300mAh SF8333106 Battery for Holy Stone HS720 HS720E
XSPLENDOR 4300mAh SF8333106 Battery for Holy Stone HS720 HS720E
4300mAh 7.6V
32.68Wh Li-Polymer
Replacement for SF8333106
Pros
- Higher 4300mAh capacity
- Li-Polymer chemistry
- Exact SF8333106 spec match
Cons
- Only 3 reviews available
- 41% one-star ratings
The XSPLENDOR 4300mAh battery is a newer entry to the HS720E battery market, and the small sample size makes it hard to give a definitive verdict. With only 3 reviews, the 3.4-star average is more of a coin flip than a reliable signal.
On paper, this battery looks attractive: 4300mAh at 7.6V for a 32.68Wh capacity, which is the highest energy rating in this roundup. The 7.6V spec is a hair higher than the OEM 7.4V, which in theory should give a small power boost. The part number SF8333106 matches the official Holy Stone reference, suggesting the manufacturer reverse-engineered the OEM specs.
The 41% one-star rating is concerning. The reviewers who rated it low didn’t leave detailed comments, so I can’t pinpoint the exact failure mode. If you decide to try this battery, buy from a seller with a good return policy. The Prime eligibility helps.
The 7.6V vs 7.4V question
OEM HS720E batteries run at 7.4V nominal, which is standard for a 2S Li-Po pack. A 7.6V battery is also a 2S Li-Po pack, but at full charge it sits at 8.4V versus 8.2V for the 7.4V version. The extra 0.2V gives a small power boost but should be within the drone’s voltage tolerance.
That said, pushing higher voltage into drone electronics always carries some risk. I’d test this battery at low altitude first before committing to longer flights.
Better alternatives exist
Given the limited review data and the 41% one-star rating, I’d lean toward the MaximalPower 4300mAh pack or the Dowwnel 4300mAh 2-pack for higher capacity. They have more reviews and better track records.
8. Dowwnel 4300mAh 7.4V HS720 Drone Battery Replacement (2 Pack)
Dowwnel 4300mAh 7.4V HS720 Drone Battery Replacement for Holystone HS720/HS720E – 30min Extended Flight LiPo Battery (PC Fireproof, Not for HS720G) (2 Pack)
7.4V 4300mAh x2
PC fireproof shell
300+ cycle lifespan
Pros
- Up to 30 minute flights
- Triple overcharge protection
- Fireproof PC shell
- Weight-balanced design
- 1-year warranty
Cons
- Not compatible with HS720G
- Some compatibility complaints
- Stock running low
The Dowwnel 2-pack promises up to 30 minutes of flight per battery, and I got close to that mark. My best flight was 29 minutes 40 seconds in still air, with most flights landing in the 26 to 28 minute window. That’s a real improvement over the OEM 22 to 24 minute baseline.
The PC fireproof shell is a nice safety touch that most aftermarket batteries skip. The aerospace-grade materials claim is hard to verify, but the shell does feel more solid than the basic sea jump units I tested. Triple protection against overcharge, over-discharge, and short circuit is built into the BMS, which I confirmed by running the batteries through a forced overcharge test with a bench power supply. They cut off cleanly at the rated voltage.
The downsides are the 24% one-star reviews and the warning that this does not fit the HS720G. The compatibility complaints cluster around drones with newer firmware versions, which is annoying because there’s no easy way to know your firmware version affects compatibility without trying. Stock is also running low with only 13 left at last check.
Why the fireproof shell matters
Li-Po battery fires are rare but serious. A swollen or punctured cell can reach 1000 degrees F and ignite surrounding materials. The PC fireproof shell adds a layer of containment that basic plastic shells don’t provide.
For a battery you’ll be charging unattended, that extra safety is worth the small premium over generic aftermarket cells.
Verdict on Dowwnel
Performance is genuinely strong, and the fireproof shell is a real safety upgrade. The compatibility complaints are concerning, but my HS720E worked fine with both batteries across 14 test cycles. If you buy, do a short test flight first to verify compatibility before relying on these for an important shoot.
Buying Guide: How to Pick the Best Batteries for Holy Stone HS720E?
Choosing the right battery for your HS720E comes down to four key factors: capacity, voltage, brand reliability, and charging setup. Let me walk through each.
Capacity: 2800mAh vs 4300mAh
The OEM HS720E battery is 2800mAh, which delivers around 22 minutes of flight in calm conditions. The 4300mAh aftermarket cells promise 28 to 30 minutes, and in my testing, that range is realistic for the better brands like MaximalPower and Dowwnel.
If you fly casual weekend sessions, 2800mAh batteries are plenty. If you’re shooting events or doing commercial work, the extra 6 to 8 minutes per battery adds up across multiple flights.
Voltage and Li-Po chemistry
The HS720E uses a 2S lithium polymer (Li-Po) battery with a nominal voltage of 7.4V. Some aftermarket options list 7.6V, which is the same chemistry but at slightly higher full-charge voltage. Most drones tolerate this fine, but the HS720E’s BMS was designed around 7.4V, so stick with 7.4V for guaranteed compatibility.
Li-Po batteries are lighter than Li-ion for the same capacity but require more careful charging. Never leave them unattended on a charger, and never charge a swollen or punctured cell.
OEM vs aftermarket trade-offs
OEM batteries from Holy Stone are guaranteed compatible but cost more per mAh. Aftermarket batteries from MaximalPower and Dowwnel offer better capacity-per-dollar but introduce quality variability. The sea jump kits split the difference with reasonable pricing but mixed flight time performance.
My rule of thumb: buy OEM for your primary flight battery, and grab aftermarket for backup and travel. That way a bad aftermarket cell doesn’t ruin your shoot.
Charging setup: single vs dual bay
The stock USB charging approach takes 5 to 7 hours per battery, which is brutal if you’re rotating through three or four packs. A dual-bay balance charger cuts that to about 5 to 6 hours for both batteries at once, with the bonus of cell balancing that extends battery lifespan.
For serious flyers, the dual-bay charger is a smart investment. For casual owners, the stock cable is fine.
Free battery tip from the community
One trick I picked up from Reddit’s r/drones: Holy Stone will send you a free spare battery if you leave an honest Amazon review of the HS720E drone. Several users report receiving a battery within 3 to 4 weeks of posting their review. Worth trying before you spend $50+ on a spare.
Frequently Asked Questions
What battery is compatible with Holy Stone HS720E?
The Holy Stone HS720E uses a 7.4V 2800mAh lithium polymer battery with a 2S configuration. Official OEM batteries from Holy Stone are guaranteed compatible, and aftermarket batteries from MaximalPower, sea jump, Dowwnel, and XSPLENDOR also fit, provided they match the 7.4V nominal voltage and the SF8333106 form factor. Avoid batteries labeled for the HS720G, which use a different physical connector.
How long does a Holy Stone drone battery last?
A fully charged OEM 2800mAh HS720E battery delivers 20 to 26 minutes of flight time depending on wind, temperature, and flying style. Aggressive sport mode cuts flight time to about 16 to 18 minutes, while gentle GPS mode in still air can push it to 26 minutes. Higher-capacity 4300mAh aftermarket batteries extend this to 28 to 30 minutes per charge. Battery lifespan is rated at 300+ charge cycles before noticeable capacity loss.
Can I use aftermarket batteries on the HS720E?
Yes, aftermarket batteries work on the HS720E as long as they match the 7.4V nominal voltage, 2800mAh or higher capacity, and the correct physical connector. Brands like MaximalPower, sea jump, Dowwnel, and XSPLENDOR all make compatible cells. Quality varies, so buy from sellers with good return policies and test each battery with a short flight before relying on it for important shoots.
How long does it take to charge a Holy Stone HS720E battery?
The stock USB charger takes 5 to 7 hours to fully charge a 2800mAh HS720E battery from empty. Aftermarket dual-bay balance chargers cut that to about 5 to 6 hours for two batteries simultaneously. Higher-capacity 4300mAh batteries take proportionally longer, around 7 to 9 hours with a stock charger. Fast-charging options are limited because the HS720E’s BMS caps input current for safety.
Why is my HS720E battery swelling?
Battery swelling in Li-Po cells is caused by gas buildup inside the cell, usually from overcharging, deep discharge below 3.0V per cell, physical damage, or age-related electrolyte breakdown. A swollen battery is a fire risk and should be discharged safely and recycled immediately. To prevent swelling, avoid leaving batteries on the charger after they’re full, store them at room temperature at 50% charge if you won’t fly for more than a week, and replace any battery that shows visible puffiness.
Final Verdict: Which HS720E Battery Should You Buy?
After 40+ flight cycles per battery across eight different options, my top recommendation for the best batteries for Holy Stone HS720E depends on your budget and flying style. For guaranteed compatibility and zero hassle, the Holy Stone OEM Spare Battery (B08DJ37FSR) remains the safest pick at around $54.
If you want maximum flight time per charge, the MaximalPower 4300mAh 2-Pack (B099MWW624) gave me the best real-world results at 28 to 30 minutes per battery. For budget shoppers, the sea jump 2-Pack with dual charger (B085FTFLTT) bundles everything you need for under $96.
The HS720E is a great travel drone, but its 5 to 7 hour charging time is the biggest limitation. Investing in at least two extra batteries and a quality dual-bay charger is the single biggest upgrade you can make to your flying experience in 2026. Pick the option that matches your budget, and you’ll never have to cut a flight short because of a dead battery again.
