I put an extra battery
in my casita
There was a sale on deep cycle marine batteries in Page (lake Powell boating). It is a sealed type... large amps I don't need but has a heck of a long sit-life.
The two are on a switch. OFF, 1, 2, both. (I am never going to click it to both probably as the two batteries are incompatible age and type and I cant go to off becasue - I think - it would be detrimental to the break away trailer brake stuff)
I charge the new big boy battery
with a charger with a "deep cycle" setting.. I charge the Casita Battery
through normal means (shore power and driving).
My question is,
1- can I tow with the new battery on?
2- can I plug into shore power with the new battery selected?
In other words will the casita's built in converter/charger charge that big duke without harm to either?
