Not really truck question but my neighbor has a boat and 3 batteries on it. One for the main motor and two for the trolling motor. So the outboard motor is 12v and the trolling is 24v. Now the issiis charging them. Without rigging up some relays and crap is there away like with a battery isolator to charge them simultaneously? Right now he has two chargers and has to unhook the 24v batteries to charge the

Lol he has 14 tractors, 2 Nova's 1 el camino, 1 late 80s square with a tbi, a couple 70s Chevy trucks, 2 boats 1 2000s Chevy truck 1 93 Chevy truck and no wife.....
He hasn't taken the boat out in a couple years but I'm trying to talk him into going fishing and having some fun

You can buy a 24volt charger
Lots of different ones on amazon

i do understand that right now he unhooks them and runs them in parallel to charge them at home. what im wondering is since his outboard has a generator on it when its running if he could somehow isolate them and charge them with all the batteries in parallel. then once he stops the outboard if he could just run the trolling motor at 24 volts.
almost if theres an isolator that would allow 12v to travel to the batteries (to charge) but still allow the batteries to be hook up in series (to run the trolling motor) or even at home to where if he hooks one battery up to the 12v charger it will charge all 3

I once owned a '64 Porsche tub that was 6v. I wanted to run a stereo with a subwoofer-12v.
Bought two deep cycle 6v batteries and built a relay system that would switch between parallel and series.
The primary battery was always charging, the secondary, when in series would drain down as I rocked out and I would have to switch it back to parallel.
I miss that car... ;)
