Deep cycle batteries

All you use is lighting?

I believe the best bang for the buck is two 6 volt golf cart batteries from Sam's Club or Costco.

OP...you need to give more info, as to use? If just for RV park, always shore power, or boondocking sometimes? Lots of good options depending.

I use Interstate brand 12V RV/Marine due to mostly shore power hookup availability.

Home built can be an especially good value.

I use it for lights and refrige while boondocking. Refrige running on gas.

best all around battery is SiO2. Pocket book "ouch".

First report I've seen on facebook of someone who disconnected their Li battery in the fall at 50% state of charge. Temperature was -5 c (23 f)at the lowest. Now they have two expensive door stops.

I am planning to buy 2 Renogy 100 amp hour batteries from Amazon for the trailer they are $189 dollars each.

That's it? A used car battery would handle that.

What? Com-on 2old, lets be nice! :) If he is boondocking, at least suggest using a couple actual deep cycles. Many seem to think a couple 6v golf cart batteries paired is a good choice.
