I've got a few 1S stock batteries from my U807 that I'm not using, soldered a couple together to make an extra 2S for my X6 Tarantula. All my 2S batteries charge to 8.4 V like they should. Just checked the voltage on the one I made and it reads bang on 10.56V and it isn't even charged. I'm no electrical expert, can someone explain how this is possible. Wired in series. Red wire from first battery soldered to black on second battery. Black wire from first and red wire from second into a JST connector
