If I understand correctly, you are wanting to run your 12v trolling motor on 24v? DO NOT ATTEMPT THIS!!! You will burn up your motor. You can run two batteries in parallel to keep it 12v and still double your battery run time.

Speck is right.....your 70 Lb. motor is a 12 volt.........80 lb. and above are 24 volts. But yes......Instead of wireing your two batteries in series for 24 volts.....Wire them in parallel for 12 volts and you will have twice as much run time.

how do you wire these two batteries to run a 12 v system ? I have always just carried a spare .. Other than not having to change on the water do I gain anything ? If I hook up a onboard charger do I need a three bank ( starter/lights are separate from trolling )or two ?

I have two 70's and they are both 24 volt.

i was kinda thinkin a 55 lb was the largest minn kota terrova you could get in a 12v.

Coach, hook a size 6 gage wire positive to positive and neg to neg. That gives you just 12 volts from 2 batteries. Hook troller to positive and neg of same battery. Batteries really need to be pretty close in size and age. But it will really extend run time without the hassle of changing battery out on the lake.
