Hey I bought this second hand RC controller with a m3p that the batteries last a flight and the battery percentage keeps jumping up and down, tried emptying the battery, it would turn off and be able to turn on for a minute like 5 times, charged it to 100 and keeps having really unpredictable battery.
Cant find the warranty since on the dji webpage wont give me the data.
Any store where I can find the batteries to replace myself? Ive seen theyre the same ones as the RCN1 controller

thanks

my batts were bad too, but i just opened up the rc and discontected the batteries and then reconnected them and they worked fine

Hello, lanadrone. Thank you for reaching out and my apologies for this inconvenience. Regretfully, we do not sell the DJI RC controller batteries since we do not recommend DIY repairs for flight safety. We suggest sending in the RC for further diagnostics.
