Powerful, compact energy for your 75–85mm FPV drones

Meet the BETAFPV BT2.0 550mAh 1S battery four-pack, designed to fuel tight micro-warfare frames with dependable stamina. Each cell sits at a featherlight 14 g and measures 69.5 by 16.2 by 6.3 mm, delivering a small, tidy footprint that helps keep weight and balance favorable for nimble flight. With a continuous discharge of 40C and bursts up to 80C, these packs offer a ready-to-use balance of energy and responsiveness across typical micro drone maneuvers. The BT2.0 platform is crafted to support steady current and steady voltage, which translates to smoother throttle response during rapid climbs and agile turns without unnecessary sag.
