Lbox88 Posted July 12, 2012 Report Share Posted July 12, 2012 Just wire the 2 batteries in parallel, + to +, - to -. Do not use an isolator. Make sure to fuse the + wire between the 2 batteries, putting a fuse within 18" of each battery. Quote UBL | Build Log Link to comment Share on other sites More sharing options...
