2 Pcs 3.7V LiPo Battery For RC Models
This pair provides compact, light, 3.7V LiPo cells with a 300mAh capacity. Designed for small RC aircraft and micro drones, the batteries use an XH254 connector for wide compatibility. With a built-in protection IC, they emphasize safe charging and longer life. Approximate weight per unit is 9 g, aiding weight-sensitive builds. Charging via a typical 5V supply with 0.5–2A current is supported, though users should confirm fit for their model’s balance and power requirements.
Blomiky 4 Pack 180mAh Li-Po Batteries
This set includes four 3.7V Li-Po cells with 180mAh capacity each and MX2.0 connectors. Weight per cell is around 5.8 g. The 20C discharge rate supports moderate power needs for small RC aircraft and micro helicopters. The included MX2.0 plug simplifies compatibility with specific model lines. A compact size (25.7 × 17.6 × 8 mm) helps minimize center-of-gravity shifts, though users should verify the battery size relative to existing compartments.
Accessory 5PCS 3.7V 400mAh + 5-in-1 Charger
This bundle includes five 400mAh cells and a multifunction 5-in-1 charger. Individual battery weight is about 9 g. The package emphasizes over-charge and short-circuit protections to extend battery life and safety. Compatible with several entry-level RC drones and planes, this option suits hobbyists who want an all-in-one charging solution and multiple batteries for extended sessions. Users should ensure the charger’s output matches their model’s voltage and charging constraints.
3.7V 400mAh LiPo With Molex Plug (5PCS)
This set offers 3.7V, 400mAh LiPo batteries with XH2.54/Molex-style compatibility. Dimensions measure about 41 × 21 × 8 mm, and each cell weighs roughly 11.5 g. The wide compatibility helps fit multiple RC planes and micro drones, especially where a robust connector is favored. The higher capacity supports longer flights, but users should confirm the Molex plug matches their device’s battery interface and charging board specifications.
Volantexrc 2Pcs 3.7V 400mAh LiPo Batteries
Two 3.7V LiPo cells provide 400mAh capacity each, with a total weight around 8 g per battery. Sold as original factory RC airplane parts, these batteries emphasize reliability and compatibility with Volantexrc models and similar platforms. The 1.48 Wh watt-hour rating indicates solid energy reserves for mid-length flights. Ensure the connector type and dimensions align with your aircraft’s battery bay and balance requirements.
Buying Guide: Key Considerations When Choosing RC Plane Batteries
- Voltage and capacity: Most small RC platforms use 3.7V LiPo packs. Higher capacity increases flight time but adds weight. Match capacity to your model’s power needs and center-of-gravity constraints.
- Connector compatibility: XH254, MX2.0, Molex, or other connectors must fit the model’s battery bay and charging hardware. Mismatched connectors can prevent charging or connections during flight.
- Discharge rate (C-rating): A higher C-rate supports more aggressive maneuvers and throttle demands. For training planes and micro drones, 20C–40C is common; larger aircraft may require higher.
- Charger features: A charger with overcharge and short-circuit protection enhances safety and battery life. Check whether it’s compatible with your charging port and power supply.
- Size and weight: Battery dimensions and weight affect aerodynamics and CG. Smaller planes need compact packs; heavier packs can reduce performance and flight time if not balanced.
- Battery life and maintenance: LiPo cells have a finite number of charge cycles. Look for batteries with protective ICs and consider storage voltage guidelines for long-term shelf life.
- Compatibility with multiple models: Some packs are designed to work with a range of RC planes, drones, and helicopters. Verify model compatibility in product descriptions to avoid fit issues.
- Safety and storage: Store LiPo batteries in fire-proof bags and follow best-practice handling to minimize risk of swelling or puncture.
Choosing a package with multiple batteries or a reliable charger can simplify maintenance and ensure consistent performance across flights. When in doubt, consult your model’s user guide for recommended voltage, capacity, and connector type to maximize safety and performance.
