on boat battery charger

hey guys looking at pro sport 11 12 amp or pro sport 11 20 amp charger not sure if bigger is better in this case any suggestions on which way to go thanks

Higher Ah output means it will work less hard to replenish the batteries.

I think bigger is better. Especially if you draw your batteries down heavily. If you are just wanting to keep them charged, the 10 amp would be fine.

Just be smart about the settings on the charger. There is usually a switch for different types of batteries, lead acid, AGM or gel cell. When I bought my boat, the previous owner had installed a charger, but the settings were all wrong. My batteries seem to be holding up fine, but I tested them this winter and they were not up to full capacity, the time they spent being charged incorrectly makes me wonder.

Had 2 pro sports, one on the Tige and one on the bass boat. Both only lasted 2 years. Just bought a MinnKota brand. Bass Pro has them on sale right now, all sizes and # of banks with a double rebate. We will see how long this one lasts. Super convenient though, great addition to your boat.

I bought a NOCO genius charger GEN4 as i have 4 batteries and have not had an issue yet. I am running XSPower D3100's instead of the Optima blue tops i used to have. i used to have issues with those blue tops and my old charger. no problems with the XSPower batteries or NOCO charger.
