Looking to put another battery in the boat for trolling cranks. Of course I'm running my main trolling battery down sooner than I would like. What kind of battery should I be looking for? Any suggestions are greatly appreciated.

I'm looking also, they tell me to either get 31's or Golf Cart batteries, if you have the room. I currently have a 24Volt 80, I have two 27's and I get approximately 4.5 hours trolling at 1.6. They say the 31's would get closer to 8-9 hours and the cart batteries a lot longer .
I assume you are running a 12 volt trolling motor since you mentioned your main trolling battery. You could get another trolling battery (preferably the same size and age of your existing one) and run two batteries in parallel. That should double your trolling time. Just connect a 6awg jumper between the positives and another 6awg jumper between the negatives.

Also, get two batteries with the largest reserve capacity that will fit in your boat

It's is 12 volt motor. A buddy of mine mentioned a dual purpose battery,
group 31. Don't know why dual purpose, should be thinking deep cycle, right?
You need a group 31 Deep Cycle
Deep cycle for sure
Yep....Dual Purpose marine batterys are for when you only have one battery and you use it to start your outboard and also run trolling motor on it.
Run one battery until it runs down then switch to the other. Here's what I have.

Go to Batteries Plus, and get the Dura Last deep cycle 29 or 31 for $110 +-. They last and last. Get the biggest 2 that will fit in your compartment. I toll all day +, Cranking in high winds and waves about 7hrs run time. I hope this helps. That's with a 24v
Don't kid yourself with a heavy fiberglass boat and the 31's. You won't get that much more time out of them as I have gone thru this process this summer, and even lengthened my trolling motor shaft to 60" which did help alot.Quote:

You are spot on Brian, and the cart batts will outlast the others as far as years of service.Quote:

Check the reserve amp hours of the batteries you're interested in. They are all rated at 25% draw. The Golf Cart batteries are 292 reserve amp hours. Better than any I've seen. I sell them to lots of the guides at Grenada.

Two 6 volt Trojen cart batteries in series, or like Spec says, two twelve's in parallel.Quote:

I like em!:fish
Pulled for 9.5 hours today at 1.8, still had more to go when we went in. Cart batts are the ticket, guess thats why they put em in golf carts. They take a heavy discharge way better.
If you are anywhere near a Sams check out the Duracell GC12. They have a pretty good price for a 12V 155AH (at 20 amp rate) golf cart battery.
I put 2 of them in series for my 24V Terrova ..... haven't ran them down yet.
31 group makes a huge difference. I got mine at oreillys. Night and day difference.

Why did getting a longer shaft TM help? Trying to learn something.Quote:

My terrova shaft was approximately 48 to 50 inches long. When I would be in the back of the boat, any hint of wind or wake would turn my boat. By lengthening the troller shaft to 60 inches, this gave it a deeper and better bite requiring a little less juice and better tracking.Quote:

Leverage plain and simple, longer shaft deeper in the water means more time on your batts.Quote:

That and Mr. Charlie yells at you if you ain't got enough shaft in the water! He can since cavitation and will ride you for having that TM to high up, specially when ain't no breeze! :RoflQuote:

I am guessing as long as it's below the bottom of the boat, the advantage is minimal to go deeper?

When pulling I run mine all the way down, that way no matter where I am in the boat there is very little change in speed or the trolling motor ramping up if its on cruise control.Quote:
