Yeah that is how I do it and normally get about 12.6-12.8 volts. I will check and see if my father-in-law has a load tester.

There's a trick to that RCC. Multi colored zip ties. Place a color on the battery somewhere, then that color on all hot leads to that batter, then a black and the same color on the ground wires to the same battery. Then repeat with a different color on each battery. Works like a charm as long as you don't completely forget a set of wires. Cell phone camera will help with that too.

I was going to buy a mk dc alternator , but after doing the math you would have to run your big motor an hour to put 10 amps back to the trolling motor battery.Not worth it to me.

I think you might have something going on with your charger. If it's a good charger, it should idle down as the batt. reaches full charge so not to cause the sulfate condition talked about earlier. I have two Optima 34M in my 5th wheel and two in my boat for the 24v circuit. I get days and days on them and have had them a couple of years now.

I have 5 total optimas (3 in the crappie boat and 2 in the pontoon boat). Only two of them have gone bad, 1 from my crappie baot with the 3 bank charger and one from my pontoon with the dual bank charger. The other batteries seem to be fine.
