12v vs 24v trolling power

[dfar]

If you are running a 12 volt motor and want to hook 2 batteries together that is called Parallel wired . Connect both Positives from both together and then both negatives together then you can have plenty of power. You will be able to charge both batteries at the same time also. I would recommend putting a 60 amp circuit breaker in one of the jumper cables for safety reasons. You should be able to use short jumper cables form the auto store.

I have had both, 24 volt much better performance.

I agree totally......

Cwright I bought some short battery cables and ran them positive to positive then negative to negative and then wired trolling motor up to that. I added a box towards the front of the boat bc there was enough room in the back of boat. I hope this helps.

Joey, how do you wire them up? I also have a 12 volt I pilot. Plenty of power, but one battery often does not last all day so I carry a spare and swap them out. Would be nice it I could just leave it hooked up.

so..I have a problem with my battery not lasting long enough....if I buy another battery...place it next to my current(get it) battery...connect the new to the old battery in parallel...do I have to do anything to the trolling motor?.....and this will get me some extra time....and then how would the circuit breaker be installed? Thanks...signed..not a genius.LOL

Not usually a good idea to have a new battery connected to an old battery ... weakest link theory. Two new batteries of close manufacturing age is the better idea.

If your current trolling motor is 12V ... two batteries connected in parallel would work fine, and give you longer trolling time. I would think the circuit breaker would still be placed inline between the batteries & trolling motor ... on the wires coming off the batteries, close to the batteries.

thanks for the advice...and my on board charger...if it is not a 3 bank charger(I have a cranking batt. and a trolling batt. now) do I need a 3 bank charger being as that there are 3 batteries......?

and when I hook these batteries in parallel the trolling motor is connected like it was previously but to the neg on one battery and the positive on the other battery and the circuit breaker would be added.....am I correct on this?

I don't think so, but I'd ask someone else who's more qualified to answer that ... maybe someone like "Catfan".

But, I have found this :


This 12-volt battery pack is connected to a single 12-volt charger. Note the blue wire designated W1. The purpose of this wire is to balance the voltage drop evenly across both batteries and each wire during charging. This is not critical for lower current chargers, but when you start to get into the 10 amp and above range, the voltage differential can be significant. The blue wire W1 must be connected to the opposite end of the battery pack as the black wire at the top of the battery pack.
