The Tattu 500mAh 2S1P 7.6V HV 25C battery is designed for F9A-B 200mm drone soccer competition, educational drone sports, indoor training, and lightweight competitive quadcopters. Its compact soft-pack construction, low 22g weight, and JST connector make it suitable for drone soccer aircraft that need responsive handling, efficient power delivery, and minimal added weight.

Tattu's stacking technology helps lower internal resistance, improve current flow, and reduce heat during repeated high-load use. This supports faster throttle response, stable voltage, predictable acceleration, and reduced power sag during climbs, rapid direction changes, defensive maneuvers, collisions, and other demanding F9A-B drone soccer match conditions.

The Tattu 500mAh battery has a 2S1P configuration, 3.7Wh energy capacity, 25C discharge rating, dimensions of approximately 52 x 24 x 10mm, a weight of about 22g, and a JST connector. It should be charged with a compatible balance charger using the correct lithium high-voltage battery settings, while pilots should verify connector polarity, cell count, charging voltage, and aircraft compatibility before use.
