Thanks for the fast reply and the insights. Should I buy the 75 amp or 100 amp model? The cost difference is negligible. Is there a downside to getting a 100 amp model? I think my stock wiring should be abler to handle either.

Hey folks. I have a 6 battery bank in my RV with 6 volt interstate flooded lead acid batteries wired in series parallel to make a 12 volt system. Each battery is 225 AH. My converter is failing and I am looking for a replacement converter/battery charger. I am replacing the stock WFCO WF9855...

From what I understand I should set the low voltage to 12.1 since I can only discharge the batteries to 50%

thanks for the help guys. a lot to learn.

Just two 12 Volts, right? I only used 4 6 volt batteries. I thought it was 450 AH before DOD factored in. What is the DOD for these? 50% and what voltage can I bring them to before recharging?

So I wired up the four 6-volt Interstate GC2-ECL-UTL batteries in series parallel and installed a battery monitor by AiLi. Trying to configure that now. Each battery says it is 225 AH. What is the depth of discharge on a 6 volt lead acid deep cycle golf cart battery? I can't find this on the...

Thanks for the guidance folks. I will sell the car batteries LOL. I just purchased 4 used lead acid GC2 6V batteries. This should get me started. I understand these give me ~50 DOD so my new 12V bank with 450AH I should realistically see 225AH.

I was told that all agm batteries are deep cycle. But I don’t think that’s right.

Nice advice thanks

Good point. I bought a load tester and tested them all. They all test good.

Hey folks. I am looking to build a battery bank for my RV. I later want to add solar panels and an inverter. I purchased 10 batteries recently at $30 each. They are all used 12V car batteries out of Mercedes Benz vehicles. Built by exide. They are 95-105 AH each and AGM. Did I make a mistake...
