what i was just wondering

Easier than wire, and a better connection for multiple batteries

 

[crfrider 10+ year member]

do people use them with just 2 batteries, i plan on running 2 in back also what would be best to run a full negative wire from the front negative battery to the back battery neg or can i just ground the batteries to a metal in the back, also same with amps, can i just run the neg from the amps to the neg on the back batteries or should i just ground them seperate to metal

also if I decide to run 2 runs of 1/0 power wire to the back would i need to run 2 neg runs also or could i just run 1

if your going to go the route of running pso and neg to the back run the same of each electricity runs in a circle the same ammount is going to go through the neg cables and the pos
