Butch50ExplorerSep 27, 2017Battery cable sizeI want to replace my single battery with 2 Grp 31 AGM deep cycle batteries. What size cable should I use to hook the batteries together? Thanks
time2rollNomadSep 27, 2017Same as the main RV cable connection. Probably #6.I recommend the main ground to one battery and the main positive to the other.Pro looking custom cables here:http://www.genuinedealz.com/custom-cables?size=56Most battery studs are 5/16" to get the right lug.
