Thread: New ulterra/New batteries/New Charger

I use a 2 bank 10 amp charger and have never had a problem with the batteries not being ready the next day.

A 2 bank 12amp probably means 6amps per bank. And yes, it will charge them ... it just may take a bit longer than a 10amp/bank charger would. If you put the charger on them when you get home, they should be ready to go by the next morning. I would think so, anyway.

Cabelas had their branded two bank 12 amp. These are supposed to have a equalization mode. Is this charger going to be good enough to take care of my charging needs. I'm known to fish 8 or so hours a day but not back to back.

It really depends on how your fishing and useing your TM......I run two group 31 batterys for my 24 v Terrova. I pull crankbaits a lot...Pulling them I sometimes run 8 hr.s continous at 1.8 mph.....Thats why I had to have the group 31s to make the 8 hrs at that usage. My charger Is a 3 bank 30 amp charger which is ten amps per bank....MinnKotta 330D...It charges them up overnite when they have been used hard like that. If your spider rigging or long lineing jigs you will be running at much slower speeds and wont be depleteing your batterys as much and a 6 amp per bank charger should bring them back overnite.

Old charger is 10 amp total @5 per bank. New one adds 2 more amps. I mainly fish brush piles.

If you haven't installed yet you might want to consider a 3 bank charger to include the crank battery, especially if you run your electronics off the crank battery. I know the motor will provide a partial charge to this battery but will not provide the battery maintainer that a charger will.

Anyone run the Pro Mariners? Seems at $150 shipped the price is right, but wondering if they last?

I use a Pro Bank 20 on my 2 series 31 trolling batteries and really like it. Had it 1.5 yrs now and works like a charm. It will optimize the 2 batteries after charging and I keep it plugged in the entire time I had it as I garage the boat. mine is a 2 bank. I use a Gen 1 4amp on the starting bat. with all the depth finders and electrical on battery, from basspro and it will charge it overnite with no problems. Just plug them in when first getting home and easy to leave plugged in till your ready to rock and roll again.

I have 2 of the ProMar 10 amp 2 bank chargers. One came on the boat and when I upgraded from 24v to 36v I didn't have enough room for a 4 bank so just installed an identical 2 bank. No issues so far.
