I recently bought the "Pro-Range INR 21700 P42A 11.1V 4200mAh 3S1P 40A/50A Discharge Li-ion Drone Battery Pack." The battery is supposed to support a 50A discharge current. However, when I tested it on my drone, which is rated for 50A, and ran it at 70% throttle, the onboard BMS started showing a low or no battery error. All the LEDs turned off. Additionally, when I performed a complete battery cycle using the iMAX B6AC, the battery capacity measured approximately 3800mAh.
Can someone please guide me? What could be the issue?
