BetaFPV BT2.0 550mAh 1S 40C/80C LiHV Battery

The BetaFPV BT2.0 550mAh 1S battery pack is custom-engineered to deliver exceptional performance, high efficiency, and extended durability for 1S micro brushless Whoop drones. Featuring a higher capacity and aggressive discharge capabilities, this pack provides additional flight time and reliable power delivery to 75mm–80mm platforms, allowing pilots to maximize their flight envelopes without experiencing premature voltage drop. The integrated BT2.0 connector utilizes solid 1.0mm banana pins and an expanded cross-sectional area, significantly decreasing internal resistance and handling high current draws much more effectively compared to traditional folded-sheet PH2.0 connectors. It establishes a perfect balance between marginal weight additions and increased flight autonomy, making it an ideal upgrade for setups currently utilizing 450mAh packs.

Features: Upgraded BT2.0 connector with 1.0mm banana pins to minimize internal resistance; Efficient high-current discharge eliminating voltage sag and false low-voltage warnings; Durable hardware design transferring pure power to high-KV brushless motors; Perfect upgrade path for increased flight times on 1S micro platforms.
