Info from Newmar on batteries

[Rjcarbo]

Per Newmar, I can add 2 additional batteries without changing the charger. As long as I have generator power or shore power the coach batteries will stay charged. It seem that they charge one at a time. The solar only keeps the engine batteries charged. I guess I will pick up the same brand & cca at the ones that are in the coach.

I would question the statement "They charge one at a time". A house bank having 2 or 4 6v or 12v all charge at the same rate, not individually. Generally your charger should be maximum rated in the range of 25 to 30% of the total amp hour rating of the total of all batteries. And yes you should use similar branded and size if they are to exist in the same power bank.
