why does a good charged battery fail?
why do some RC lipo battery's charge good ,hold a charge yet when you fly your RC plane they die quick?
I use a 2S 7.4 volt 1300mah battery that came with my drone and the battery isn't swollen , looks, good yet will only fly the drone for 2 minutes, a good battery that I also have fly's the drone for 6-7 minutes
