I have an older model trolling motor that i haven't used before. I believe it is a 12/24? Which I think means it can run off of a 12v battery or 2 12 v batteries. It is probably about 40lbs of thrust.

1. How much less power will the motor have with just one battery hooked up?
2. How long will the motor operate on one battery?Two?
3. What type of wiring configuration would i need? One cranking battery tied to a trolling battery hooked up to the trolling motor?
4. Would my outboard recharge my cranking battery and my trolling motor battery?

I would appreciate your replies.

Also would a regular cranking battery work instead of a deep cycle battery? Cheaper to buy the walmart cranking for 39 with the 2 year free replacement.

more juice(24v)=less amperage=longer running time. Power is power..you have #40 thrust max. Yes ,you can charge all batteries off outboard IF it is rated to do so.

get the deep cycle battery for trolling

The engine will only charge the batteries if they are in parallel. To get 24v's they must be in series and thus only the battery that the engine starts from will be charged. To put the bateries in series the positive on battery one is tied to the negative of batery two. Black wire comes off of battery one negative, red wire comes off positive of batt 1, the third lead comes off the positive of batt 2. The voltage acrossed the red and black will be 12 volts, and between the third wire and black wire is 24 Volts.

Would you recommend running the batteries in my boat in series this way? How would this effect me when I went to charge them? Thanks for the info.
