Sea Jump offers a two-pack option that mirrors the 3.8V, 1900mAh specification. Each battery weighs around 41 g and uses a 1S configuration. The pack is designed to deliver higher flight time due to the two-battery power delivery. Its emphasis on a ready-to-use rechargeable pack helps minimize downtime between flights, making it ideal for pilots who want reliable backup power for HS440-class drones.
Sea Jump 3.8V 1900mAh for HS440 Aerial Drone
This 3.8V 1900mAh battery is specifically marketed for the HS440 Aerial Four Axis Aircraft and similar folding remotes. The 25C rating suggests solid performance for standard flight tasks, with a built-in safety mechanism enhancing user protection during charging and operation. Its compact design mirrors the HS440’s form factor, helping maintain flight balance with minimal bulk.
E88 Series 3.7V 1800mAh Battery
This battery targets E88, E88PRO, E525, P5 PRO, P15, and similar drones in the E88 family. It measures 72 x 29 x 12 mm and weighs approximately 19.8 g, enabling quick swaps to minimize downtime. With an 1800mAh capacity, it delivers extended power for compatible models, though it is not universal across different drone families. Always confirm compatibility before purchasing.
Blomiky 4 Pack 1S 3.8V 450mAh Battery
This Blomiky four-pack provides compact, low-capacity options with a PH2.0 plug suitable for EZ Pilot S Freestyle brushless quadcopters. At 450mAh and 12 g per cell, these are best for lightweight or backup use where long flight times aren’t critical. The 3.8V configuration remains consistent with the other options in this guide, ensuring compatibility with smaller 1S drones.
Buying Guide: Key Purchase Considerations
- Compatibility: Confirm the drone model and connector type. Small differences in plug types, dimensions, and cell configuration (1S vs multi-cell) can prevent a battery from fitting or charging correctly.
- Voltage and Capacity: Most HS440-compatible batteries use 3.8V 1900mAh. Higher capacity can extend flight time but may add weight. Balance runtime with weight for optimal handling and balance.
- Weight and Size: Lighter packs reduce strain on the gimbal and motor system. Check measurements to ensure the battery fits in the existing bay without obstruction.
- Discharge Rate: A higher C-rating supports bursts of power for acrobatic maneuvers and stable throttle response during lifts. For basic flight, 25C is common, with higher values offering extra performance.
- Safety Features: Look for built-in protection against overcharge, short circuit, and thermal issues. These features improve safety during charging and usage.
- Price and Pairing: If buying in packs, ensure you actually need multiple spares. Consider whether the pack’s total price aligns with your budget and flight needs.
- Brand and Warranty: Reputable brands often provide longer-term reliability and a more straightforward warranty path if issues arise.
Additional Considerations
When choosing between single 1900mAh batteries and multi-pack options, it helps to assess your typical flight duration and the frequency of battery swaps. If you fly in environments where quick turnaround is essential, a second pack can minimize downtime. If you primarily use a single drone, a high-quality replacement that closely mirrors the original specifications offers the simplest solution. Always inspect batteries for signs of wear or damage before use, and replace them if swelling or cracking is observed.
Maintaining Battery Health
Charge batteries with the appropriate charger, avoid exposing them to extreme temperatures, and store them in a cool, dry place. Do not leave charging batteries unattended for extended periods, and follow the manufacturer’s guidelines for discharge and storage. Regularly check connectors for corrosion or looseness, and ensure the battery bay is clean and free of debris that could interfere with connections.
Technical Snapshot
- 3.8V nominal cells commonly used for HS440-class drones
- 1S configurations favored for lightweight, compact designs
- 1900mAh capacity balances runtime with weight for balanced flight
- Protected charging circuits improve safety during charging cycles
In summary, the five batteries presented offer practical options for pilots seeking extended flight times or reliable spares for HS440-like folding drones. Each option brings its own balance of weight, capacity, and safety to meet varied flying styles and needs.
