So I have a Minn Kota MK 315 three-bank onboard charger, this one:


Right now it is charging two batteries in a 24V trolling motor set and one battery for cranking. I am upgrading to a 36V trolling motor and want to verify that I can use all three banks to charge the three trolling batteries. AFAIK the isolated charger setup is the same on all three banks so it should work. I do realize that I'll need another charge maintainer for the cranking battery.

Eventually I will move to a four-bank charger but this is just for now since I spent a bundle on the new trolling motor.

Thanks

The charger will work. get a separate charger for the starting battery,

Yep Bruce that is what I am thinking. I may just use the three bank forever, and use a separate battery tender or the like for the cranking battery. Hell I think I have one already.

Agreed
