Charging mult. batteries at once.

5 posts in this topic

I would like to charge 2 or 3 batteries at once in my fish house.... I would also like to use the "juice" from all 3 of them to run my furnace, lights, ect. I do have a HONDA generator to run at night when we don't fish on LOTW....

Connect them parallel. Power will draw from them all and one charger will charge them all.

The batteries in my fish house (two) are wired in parallel and feed everything in it. I have a single bank on board charger and charge them both at the same time. In the evening I start my generator and watch a movie as long as I am charging batteries anyway. I run my camputer fans all night and in the morning I start the generator, make a pot of drip coffee and charge them again for a while. I don't know what size your batteries are, but mine are small 30 amp batteries and a six amp on board charger. This works great for me. When I am home I keep the ice house plugged in and my batteries stay conditioned. You may want a charger with more amperage if you have larger batteries.

Yep - connect the batteries in parallel. Positive to positive to positive in this case and negative to negative to negative.

You can get by with a single bank charger, but it'll take longer to charge the three batteries unless you have a high amp single back charger.
