I have (3) 12 volt 100ah lead acid deep cycle batteries in parallel for a total of 300ah that are charged thru the travel trailer WFCO power converter / charger whenever plugged in to 120volt outlet. I'm Looking to be able to automatically have the12 volt load disconnect from the batteries when they hit 50% to prevent damage then come back on when i recharge thru the WFCO.
1. can i use the batteryprotect? Got a wiring diagram?
2. While I have a total 300amps, I'll never use that much amperage and estimate at the most I would use 60 to 100Amp. What size would be necessary?
