It works fine with 1 x 100Ah LIfepo4 battery connected, but when I connect 2 batteries in parallel and configure it as 200Ah, it's only showing me 50% capacity. I can't setup the batteries in Series because my Renogy 2000w interver is 12V only. An I toast? I thought it would just see 1 200Ah battery connected. I'm not sure if I move the monitor cable to the other battery if it would make a difference.
