Battery /onboard charge set-up

Recommended Posts

Currently I have two batteries in my boat. One battery is going to the outboard motor and accessories (radio,locators,lights...) while the other battery feeds the trolling motor (55lbs). Each have a designated one bank onbaord charger.

I have room for a third battery (with some engineering work) and wanting to run a group 24 Marine Starting battery (lead-acid) to the outboard, group 24 AGM to accessories, and group 27 AGM to trolling motor.

1)Do you guys have your outboard motor batteries connected to your onboard charging system? Do you notice your atarting batteries needing a charge? (I'm running a 90hp Mercury 2 stroke-2007)

2)Will a three bank onboard charging system charge two different battery types (2 AGMS, 1 Lead-Acid)at the same time? Most charges say they'll charge all battery "types" but not sure if that can happen at the same time...

Since I have two onboard charges, I'm trying to see if I can get away with purchasing an onboard charger for my lead-acid outboard battery while using the charges on the accessory and trolling motor battery.

Thanks,

CC

Finally heard back from the manufacture. Per the charger I am looking at, it has one setting for both lead-acid and AGM and another setting for gel. So in my use, this will work fine but if you were using a gel battery in the mix with lead or AGM, one would need a separate charger.

Still curious if you guys find a need for an onboard charger for your starting battery or do you find the motor/alternator keeps it charged?

When I upgraded from monochrome depth finders & gps's to color units I needed to charge my starting battery if the trip didn't have several long runs across the lake.

I had issues in the past while using the accessories and not running the outboard my GPS units were turn off when I started the outboard. I went to a dual purpose battery at the outboard. I have a two bank charger that charges trolling batteries but last year I installed a stealth dc alternator charger that keeps all 3 batteries in check when running the outboard.
