oh okay so that's why it wasn't working, i soldered some Xt60's to my damaged Lipo and put them into parallel an the ebike turned on so i have two brand new LIPOs but one is damaged and a cell won't balance all other cells seem fine though.
My two main questions at current
1).If a lipo goes under 3V does that means it's dead? all other cells remain over 3V apart from 1 cell
2).My solder station is metal and i never use LIPOS, so the LIPO went BZZZZZZzzzzz so i thought it was dead, should i trust it, or is it the Omen waiting to kill me in my sleep
