2024-03 I used to have a bank of four 12V/7A gel batteries rescued from several UPSes but they died finally, I used them with the 32W panel and the Morningstar controller. When I replace the battery bank I want to get a single LiFePO4 battery, probably around 20AH. I already got the Renogy before the lead batteries died. I am holding off getting another battery so this project is on hold.
