Compatibility
This 3.7V LiPo is compatible with small flight controllers and ESC stacks that accept 1S input, such as BetaFPV, Happymodel, or custom Arduino-based drone controllers. It works with most micro brushed or brushless motor setups under 24A total draw. Ideal for 65mm-85mm whoop frames and toothpick builds.
Wiring Notes
Connect the red wire to positive (VCC) and black to ground. The JST connector is polarized; ensure correct orientation. Never exceed the 24A continuous current limit, and always monitor battery voltage to prevent over-discharge below 3.0V.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with BetaFPV 65S?
Yes, the JST connector and 1S voltage match the BetaFPV 65S whoop. Ensure the battery physically fits the frame mount.
What charger should I use?
A basic 1S LiPo charger with JST compatibility, such as the ISDT Q6 Nano or a simple USB charger, works. Set to 4.2V and charge at 0.8A (1C) or lower.
How long does it last in flight?
With normal flying, expect 3-5 minutes on a typical micro quadcopter. Flight time varies with throttle usage, weight, and motor KV.
