View Full Version : dual battery connections

Quick question, I use to have dual batteries with the fancy switch to go between one or two or both. I don't have that anymore is there any problem just connecting the two positives & negatives together? Seems like it shouldnt matter if both batteries are 12v.

From what i can remeber as long as both batteries are the same it shouldnt madder.
