hillger Posted April 3, 2015 Report Share Posted April 3, 2015 Adding a second battery is it a must to add a battery isolator as well? Quote Link to comment Share on other sites More sharing options...
RooTxBeeR Posted April 3, 2015 Report Share Posted April 3, 2015 No, if the batteries are same brand and battery type you can get away without using one. You mainly want to use one of those, when you have multiple batteries that rest at different voltages.

hillger Posted April 3, 2015 Author Report Share Posted April 3, 2015 Thanks sorry for posting twice. First time adding an additional battery so I wasn't sure both batteries are 12volts at 750 CCA its not a beast of a system by any means I just wanted to be on the safe side.
