Hi, I am brand new to solar and battery back-ups and recently installed a Renogy 200w off grid solar kit to the roof of my sprinter van as part of my conversion to a camper. Everything seemed fine when I first set everything up (batteries displaying similar SOC % and voltages, and amperage draw while in use). Recently through on my Renogy DC Home app I've been seeing one battery charge to usually 14.2 volts and discharge fine. However, the other battery seems to only charge to 13.6 or 13.7 and appears to have no draw coming from it (maintains 100% SOC and voltage) when using 12v power, but the other battery drains. If I add a large load to my inverter (like a heat gun) the "sleepy" battery seems to "wake up" and I start to see an even amperage draw from both batteries.
I'm stumped and any help is greatly appreciated
