I have 2 AOlithium 12 volt 100AH with bluetooth and 2Humsienk 12volt 100AH parallel and series. I monitor their balance with the AOlithium SOC display on the app, monitoring their individual SOC. It hasnt reported falling out of balance by even 1 percent. This morning I woke up and 1 battery is in over discharge protection at 0% SOC and the other is reporting 38%. I had to go to AOlithiums website to look up Over discharge Voltage protection and release numbers, as I realized its not published in their manual. The one at 0% is slowly rising in voltage from being paralleled and series. But its at 2.72V per cell and saying it wont wake up until 3.0 So Im going to be here a minute without buying a "12volt" "smart charger"...nice.
I only had a 100 watt fridge on it, but it looks like the 400 watt defrost kicked in on the fridge at the crack of dawn and ruined me. I'm starting to think bluetooth SOC is just complete nonsense. Im not liking a 400 watt load slam hammering a battery into BMS protection at 38% reported SOC either. If the Battery would come out of protection, I can solar charge it. Ive pulled all the load off and the sun is out to produce the AIO inverters load.
