I've been following this thread with some interest, because replacing my 4D 12 volt battery
in my boat is a one of my winter projects.
The boat is a 1998 Beneteau Oceanis
352 with Bene's standard two battery system; 1 12-volt starting battery in the engine compartment and a large house battery in a compartment under the aft berth. In addition to the 50 amp engine alternator
, we have a 20 amp shore-power battery charger
installed. Both the house and the starting battery have cut-off switches, and IIRC, there's a third switch to isolate both at once.
Attached is a diagram that I found on the web that shows what I'm considering using to replace the house battery. I was thinking about buying
4 6-volt batteries and wiring
them to create the equivalent of 2-12 volt batteries. If I understand correctly, this is what most folks do when going with the 6-volt systems.
What is the best way to recharge the 4x6-volt system, then? Do people just treat such a system just like a big 12 volt battery, or are there special considerations? Does anyone have a diagram of how to properly hook up a chargers to a 4x6-volt bank?
Thanks for your help,
