add 2nd battery
I have a 4 year old 5th wheel that I just bought and it has one battery that is AGM 12v 110am @c100 12v 100am C20 it gets charged from a solar panel and I assume from my truck. My question is, can I just add one more battery that says AGM 12v 110am @c100 12v 100am C20 and hook up the 2 positives and the 2 negatives or will it not get charged correctly or ? My goal is to just have a bit more battery life as inexpensively as possible. I don't boondock, but once a while I am a campground without electricity and stay for one night. I do have a generator but it would be nice if my batteries would keep my 110 fridge running most of the night with the inverter and batteries. I have a 40' 5th wheel. Thx
