quick snap on/off large post battery clamp
if the 12v plug in is not a long term solution for quick set up...maybe these might work.. anyone using them?
thinking these snap on clamps on the large post might touch the cable rings over the small post.. any problem if they touch? seems like the big post and little post are connected anyways.. don't think it would be an issue... but...
trivia question...anyone know why one end of the parallel battery cable is copper, and the other end not? Just curious.
