RE: Need help, pretty please
you know how they are wired in series......the MAIN power line is the black and red with connector, then from there one red wire to the other( 2nd power line) connector with both of them being red.... then obviously it goes one red and one black to the esc........ anywho with that being said the main power the red and black wires that the battery connects to is always the hot one.... it doesn't matter if swap the batteries around...the primary battery wires are the ones getting hot
