With a whopping 50C continuous discharge currents and 100C burst currents, Pro50 LiPo packs allow brushless motors to crank out the massive power that high-performance aircraft demand. And you don't have to worry about extended use — you can use Pro50 packs OVER 300 TIMES, and they'll still deliver like they're brand-new. Charging is surprisingly quick using 6C maximum charge current, so you'll spend more time in the air, and a wide range of voltages and capacities means there's a Pro50 pack that's ideal for your large-scale or 3D aircraft.
