I'm looking into the possibility of installing an On-Board Battery Charger on my dual battery bank. I just don't know what amp is needed or required. I am running FM and VHF radios and Lowrance 334 during along with the live well each outing. Should I look for a 5 amp, 8 amp or 10. Of course each has their price differences.

Doesn't matter what your running. Its not going to charge them under way. Thats what the alernator on your motor is for, if I'm understanding you correctly. I have a triple bank on-board charger on mine (6amp Guest) and I plug it in when I'm done fishing and it takes about 4 hrs to have my batteries completely charged. Obvisouly the higher the amperage the faster the charge. Although the lower the amperage the better the charge from what I have read.

On my bass boat I had a double bank and a single bank and amperage was 2A's and by morning my batteries were completely topped off.

I just got a new Minn Kota 2 bank charger from Academy it was less than the Quest from Boaters World and has a longer warranty. It is heavy at 12.4 lbs and I did not mount it in the boat if I travel I can always take it with me so I thought no need to add weight or take up space in the boat. Also cut the eyes off and put on clips. I have easy access to my batteries.


Good Luck, Ken

I just ordered the Cabella's 2 bank, and it sends the most charge to the weakest battery, so it says. I am anxious to try it out. The monitoring electronics in the newer chargers are worth the cost.
