On Board Charger

[loggybayouboy]

Plan on buying a new boat with the intentions of keeping both trolling motor batteries under the front deck. I'm wanting to mount an onboard charger near them as well but my dilemma lies in also charging my depth finder battery which is a smaller 12v like in a deer feeder. I typically add and remove my tm batteries and depth finder rig 2-3 times a week during duck season but leave it all on permanently February-October. Will a typical 3 bank on board charger do the job? Or do I only need 2 banks if the tm batteries are wired together? This is my first experience with a 24v or on board charger I typically just place my trolling motor battery on front deck and use alligator clips. Thanks

Do not hook a deer feeder battery (even 12v) up to a on board charger. Deer feeder batteries take a small charger you can buy where you get those batteries, these are low amp chargers, even less than the 2amp chargers/maintainer type some use.
