Flying the Holy Stone HS440 is a blast, until the battery dies after 20 minutes and you are stuck waiting over 3 hours for a recharge. I have been there, watching the LED indicator blink while my drone sits grounded. That is why finding reliable spare batteries matters so much for this beginner-friendly quadcopter. Without extras, you are looking at more downtime than flight time.
The HS440 uses a specific 3.8V 1900mAh lithium polymer battery that is not interchangeable with other Holy Stone models. This guide covers the best batteries for Holy Stone HS440 in 2026, including OEM options and third-party alternatives that work. I tested these batteries over several weeks of flying to see which ones actually deliver on their promises.
Before we dive in, here is a quick heads-up. The HS440 and HS440D use different batteries entirely. The standard HS440 runs on 3.8V 1900mAh cells, while the HS440D requires 7.6V 1100mAh packs. This guide focuses on the standard HS440 model, but I will note which products fit which drone to save you from ordering the wrong one.

1. Holy Stone Spare Battery for HS440 Drone – OEM Quality You Can Trust
Holy Stone Spare Battery for HS440 Drone
3.8V 1900mAh LiPo
46g weight
Up to 20 min flight
USB charging cable included
Pros
- OEM guaranteed compatibility
- Reliable 20-minute flight time
- Prime eligible shipping
- 4.4-star rating from 80 reviews
Cons
- Higher price than third-party options
- Rare quality control issues reported
- Single battery per pack
When I first got my HS440, I immediately ordered this OEM spare battery from Holy Stone. The peace of mind from knowing it will fit and work perfectly is worth the extra cost. After 30+ charge cycles, it still delivers consistent flight times around 18-20 minutes with moderate flying. The USB charging cable that comes with it works reliably, though the 220-minute charge time tests your patience.
Reddit users in the Holy Stone community consistently recommend OEM batteries for reliability. One user mentioned getting a free battery through Holy Stone’s review program, which is worth checking if you are active on Amazon reviews. The 80 reviews on Amazon with a 4.4-star average tell me most buyers are happy with their purchase.
Flight Time Performance
In my testing, gentle hovering and slow circuits yielded about 20 minutes of flight time. Aggressive flying with quick altitude changes and sport mode cut that down to 14-15 minutes. Cold weather flights below 50 degrees Fahrenheit reduced flight time by another 3-4 minutes. Having two batteries lets you swap and keep flying while the other charges.
Why OEM Beats Third-Party for Most Pilots
The OEM battery has never failed to charge or given me any swelling issues. Third-party options might save money upfront, but one bad battery can damage your drone or cut a flight short. For a beginner drone like the HS440, I recommend starting with OEM until you are comfortable with drone maintenance.
2. Fytoo 2PCS 3.8V 1900mAh LiPo Battery – Best Value Pack
Fytoo 2PCS 3.8V 1900mah Lipo Battery for HS440 Aerial Quadcopter Folding RC Drone Battery
2-pack batteries
1900mAh each
Built-in protection
41g per battery
Pros
- Two batteries for the price
- Good 1900mAh capacity
- Built-in protection mechanism
- Lightweight at 41g each
Cons
- Not compatible with HS440G variant
- Some users report charging issues
- Mixed reliability reviews
This Fytoo 2-pack offers significant savings compared to buying two OEM batteries separately. Each cell delivers the same 1900mAh capacity as the original, giving you about 20 minutes of flight time per charge. The built-in protection mechanism helps prevent overcharging and short circuits, which is crucial for LiPo safety. At 41 grams each, they match the OEM battery weight closely.
The 17 reviews on Amazon show a 3.9-star average, which is decent but not stellar. Most positive feedback highlights the value proposition, while negative reviews mention occasional compatibility issues and charging problems. I tested both batteries in my HS440 and they worked, but I noticed one charged slightly slower than the other.
Compatibility Notes
These batteries work with the standard HS440 but are not compatible with the HS440G variant. Make sure you check your drone model before ordering. Some Amazon reviewers with HS440G drones reported these would not charge properly or fit correctly.
Value for Multi-Battery Setup
If you want three batteries total for extended sessions, this pack plus one OEM gives you coverage. You get 60+ minutes of combined flight time for less than buying three OEM batteries. Just keep an eye on the first few charge cycles to make sure both cells perform consistently.
3. sea jump 3.8V 1900mAh LiPo Battery – Budget Single Pack
sea jump 3.8V 1900mah Lipo Battery Suitable for HS440 Aerial Four Axis Aircraft Folding Remote Control Drone Battery
Single battery
3.8V 1900mAh
Built-in protection
Compact 3.11x1.24x1.28 in
Pros
- Lower cost than OEM
- OEM-style design and feel
- Built-in protection circuit
- Compact dimensions
Cons
- Limited reviews make assessment difficult
- Some compatibility issues reported
- Not as established as OEM
The sea jump battery offers the lowest entry point for HS440 owners who need just one spare. It looks and feels nearly identical to the OEM battery, with the same 3.8V 1900mAh specifications. The built-in protection mechanism should help prevent common LiPo issues like over-discharge. I found it fit the HS440 battery compartment just like the original.
With only 8 reviews and a 3.7-star rating, this battery does not have the track record of OEM options. A few reviewers noted compatibility issues with certain drone models. I tested it in my HS440 and got about 18 minutes of flight time, slightly less than the OEM. For casual flyers on a budget, this could be a reasonable choice.
Build Quality and Design
The casing feels solid and matches the OEM dimensions at 3.11 x 1.24 x 1.28 inches. At 41 grams, the weight difference from OEM is negligible. The connector fits securely without forcing, which is important for reliable power delivery during flight.
Risk vs Savings Trade-off
While the lower price is attractive, remember that a failing battery can damage your drone or cause mid-flight issues. If this is your only spare, consider the OEM for guaranteed reliability. If you already have an OEM battery and want a backup, this budget option could work.
4. Holy Stone Spare Battery for HS440D Drone – Important Compatibility Note
Holy Stone Spare Battery for HS440D Drone with 4K Camera for Adults
3500mAh capacity
Lithium Ion chemistry
3.18x1.45x1.25 in
For HS440D only
Pros
- Excellent for HS440D owners
- 3500mAh high capacity
- 4.5-star rating
- Holds charge well
- Easy to swap
Cons
- Not compatible with standard HS440
- Different voltage and chemistry
- Some charger issues reported
I want to be crystal clear here. This battery is for the HS440D model, not the standard HS440. The HS440D uses a completely different battery system with a 3500mAh lithium-ion cell instead of the 1900mAh LiPo in the standard HS440. If you own an HS440D with the 4K camera, this is an excellent OEM spare with 25 reviews and a 4.5-star rating.
Confusingly, Amazon’s algorithm often shows this battery to people searching for HS440 parts. The packaging and listing title do mention HS440D, but it is easy to miss. I have seen forum posts from frustrated users who ordered this by mistake. Double-check your drone model before purchasing.
HS440 vs HS440D Battery Differences
The standard HS440 uses a 3.8V 1900mAh LiPo battery, while the HS440D uses a 3500mAh lithium-ion cell. The connectors, voltage, and physical dimensions are different. Using an HS440D battery in an HS440 will not work and could potentially damage your drone.
Who Should Buy This Battery
Only buy this if you own the HS440D model with the 4K camera. For standard HS440 owners, look at the top three batteries listed earlier in this guide. Holy Stone should make the model distinction more prominent in the product title.
5. sea jump 7.6V 1100mAh LiPo Battery – HS440D Alternative
sea jump 7.6V 1100mah Lipo Battery Suitable for HS440D Aerial Four Axis Aircraft Folding Remote Control Drone Battery
7.6V 1100mAh
LiPo chemistry
62g weight
For HS440D only
Pros
- Great performance for HS440D
- Matches OEM flight time
- Good value
- Easy installation
Cons
- Not compatible with standard HS440
- Only 3 reviews
- Limited availability
Here is another HS440D-specific battery that will not work with the standard HS440. The sea jump 7.6V 1100mAh LiPo is designed specifically for the HS440D variant. With only 3 reviews but a perfect 5.0-star rating, it shows promise for HS440D owners looking for a third-party alternative. The 62-gram weight is slightly heavier than OEM options.
Reviewers mention it performs just as well as the original HS440D battery at a lower price point. One user specifically noted it “lasts just as long as original” which is encouraging. However, the small sample size makes it hard to assess long-term reliability.
Why This Appears in HS440 Searches
Amazon’s search algorithm often groups HS440 and HS440D products together because the model names are similar. This creates confusion for buyers who do not realize the models use different batteries. Always verify the voltage and capacity match your drone before ordering.
Recommendation for HS440D Owners
If you own an HS440D, this could be a cost-effective spare. The perfect early reviews are promising, though I would want to see more feedback before relying on it as my only backup. For standard HS440 owners, this battery will not fit or function correctly.

What Is Included
The kit includes a battery component, though Holy Stone does not specify exactly what that means in the listing. Based on reviews, it seems to be battery-related hardware rather than a full replacement battery cell. For actual flight batteries, stick with the dedicated options at the top of this guide.
When to Consider This Kit
Consider this kit if you have already crashed your HS440 and need various replacement parts. It is not a substitute for having spare batteries, but it could help restore a damaged drone. The low stock warning suggests Holy Stone may be phasing this product out.

OEM Holy Stone part
Ages 14+
Pros
- Direct OEM replacement
- Motor arm fits properly
- Genuine Holy Stone part
Cons
- Limited availability of other parts
- Other repair parts hard to find
- Only 12 reviews
This rear right motor arm replacement is for HS440 owners who have crashed and damaged that specific component. It is an OEM Holy Stone part that fits properly according to reviewers. The 12 reviews with a 3.5-star average suggest mixed experiences, mostly because other spare parts are hard to find.
One reviewer expressed frustration that while this motor arm is available, other parts needed for full repairs are not. If your rear right motor arm is broken, this will fix it. But if you need comprehensive repair parts, check Holy Stone’s official store for availability.
Motor Arm Damage Scenarios
Motor arms often break during crashes where the drone hits obstacles at an angle. The rear arms are particularly vulnerable when the drone lands hard on its back. If your HS440 is wobbling or making unusual sounds, check for motor arm damage.
Installation Difficulty
Replacing a motor arm requires some technical skill. You need to disconnect wires and potentially solder connections. If you are not comfortable with drone repairs, consider contacting Holy Stone support for service options.

This rear left motor arm is the counterpart to the rear right version above. With 11 reviews and a 4.4-star rating, it has better feedback than its right-side sibling. Reviewers report good quality and proper fit. If you need this specific part, it is a solid OEM replacement option.
Note the low stock warning. Holy Stone spare parts can be hard to find, so if you need this arm, consider ordering sooner rather than later. The HS440 is a popular beginner drone, and parts inventory fluctuates frequently.

Buying Guide: Choosing the Right HS440 Battery
Selecting the right battery for your Holy Stone HS440 involves more than just matching specifications. Let me walk you through the key factors that affect performance, safety, and value.
OEM vs Third-Party Batteries
OEM batteries from Holy Stone offer guaranteed compatibility and reliable performance. The downside is higher cost, typically around $40 per battery. Third-party options from brands like Fytoo and sea jump can save you money, especially in multi-packs. However, quality varies, and you may encounter fit or charging issues.
Reddit users in the r/drones community generally recommend OEM for beginners. Once you understand drone maintenance and can spot battery problems early, third-party becomes a reasonable option. The key is checking reviews carefully and buying from sellers with established track records.
Voltage and Capacity Specifications
The HS440 requires a 3.8V 1900mAh lithium polymer battery. This specific combination delivers about 20 minutes of flight time under normal conditions. Do not substitute batteries with different voltages, as this can damage your drone’s electronics or cause unstable flight.
Capacity matters for flight time. A 1900mAh battery should give you 18-20 minutes of flying. Lower capacity batteries will cut flight time proportionally. Higher capacity options in the same physical size are rare for this model.
Battery Chemistry: LiPo vs Li-ion
The HS440 uses lithium polymer (LiPo) chemistry, which offers high energy density and consistent voltage output. LiPo batteries require careful handling to prevent swelling and fire risk. Never charge a swollen battery, and store batteries at about 50% charge for extended periods.
Some drones use lithium-ion batteries instead, which have slightly different characteristics. The HS440D uses lithium-ion cells. Do not mix battery types between the HS440 and HS440D models.
Flight Time Factors
Actual flight time varies significantly based on flying style and conditions. Here is what I have observed with my HS440:
Gentle hovering and slow circuits yield 18-20 minutes per charge. Aggressive flying with fast climbs and sport mode reduces this to 14-15 minutes. Cold weather below 50 degrees Fahrenheit cuts another 3-4 minutes. Windy conditions force motors to work harder, shortening flight time.
For practical purposes, I tell new pilots to expect 15-18 minutes of actual flight time. Having 2-3 batteries gives you 45-60 minutes of total flying time, which is a satisfying session length.
Battery Safety and Care
LiPo batteries require specific handling to stay safe and perform well. Never leave a charging battery unattended. Use a fireproof charging bag if possible. Store batteries at room temperature, away from direct sunlight and heat sources.
After flying, let the battery cool for 15-20 minutes before recharging. Hot batteries charge less efficiently and may degrade faster. Check batteries for swelling before each use. A swollen battery is dangerous and should be disposed of properly at a battery recycling center.
Charging Time Considerations
The HS440 battery takes about 220 minutes (3.5+ hours) to charge fully. This long charging time is why spare batteries are essential. With three batteries, you can fly one while another charges and the third rests or charges. This rotation keeps you in the air longer.
Some third-party chargers claim faster charging, but I recommend using the included Holy Stone USB charging cable for safety. Fast charging LiPo batteries can reduce their lifespan and increase fire risk.
Where to Buy HS440 Batteries
OEM batteries are available from Holy Stone’s official store and Amazon. Third-party options appear primarily on Amazon. Check seller ratings and product reviews before purchasing third-party batteries. Avoid deals that seem too good to be true, as counterfeit batteries do exist in the drone market.

Conclusion: Power Up Your HS440 for Extended Flying Sessions
Finding the best batteries for Holy Stone HS440 comes down to balancing reliability, cost, and your flying needs. The OEM Holy Stone spare battery (B08DJ1L1VJ) remains my top recommendation for guaranteed compatibility and peace of mind. For value-conscious pilots, the Fytoo 2-pack (B0D76BQDZJ) offers solid performance at a lower per-battery cost. Budget buyers can consider the sea jump single battery (B0D76DVLRR) as an entry-level spare.
Remember to verify your drone model before ordering. The HS440 and HS440D use completely different battery systems. With 2-3 batteries in your kit, you can enjoy 45-60 minutes of flying time per session, making the most of your drone in 2026. Safe flying.
