Dual Battery in my 5th wheel.

[prelucir]

I have two battery compartments in my 5th wheel. However, only one has the batter connections coming from it. An I simply add the second batter and connect to the same posts that my other batter are connected to? I can by the cables from Napa in any length that I want.

I am just concerned that by adding a second batter that I will end up with 24 volts vs. 12 volts.


I have a 2017 Heartland Bighorn 3575EL.


Thanks for the help.

Hook two 12v batteries in parallel (doubles capacity but not voltage) by hooking positive to positive and negative to negative (reds together, and blacks together).
