solar charging

I am no expert, but in my camper I have two batteries that are wired to a Steca controller regulator. I then just plug our folding 120 w solar panel into the controller, via an anderson plug, and I can either select a particular battery to charge, or have both charging at the same time. The controller will feed the appropriate power to each battery as required. In other words, no problems with charging both at the same time with our controller. Kevin

Yes you certainly can. However ideally you want the 2 batteries to be similar in size(amp wise and same construction..ie..gel,calcium etc)

As mentioned above its all possible.....but....there are several ways of doing it to achieve best advantage in that situation.

what is the set up you have a what sort of regulator are you using.

remember, most of the modern battery charging systems work best when they have a direct relationship between a single charger and a single battery.

if you have two identical batteries, same size, type, constructon, age and condition, if correctly connected they will behave mostly as one large battery.

it is worthwhile seperating them and charging them seperately from time to time.

anything other than that and there are other methods that may give better advantage.
