BMV-712 SOC is always wrong. 3 Battleborn Batteries.
Hello everyone. I sure this has been covered somewhere but I haven’t found the answer yet.
I have the BMV-712 smart monitor and it seems it’s never correct on the SOC. I have charged the batteries several times to full charge. During this process I run nothing off of them and charge them to the point it shows 0.2 Amps or less going into them and 14.4 volts. At that point I synchronize the BMV to 100%.
Now one would think the SOC would go up and down correctly with the voltage but the BMV-712 shows a low SOC all the time.
All of the settings are correct for the battleborn batteries firmware is up to date.
The system has 800 watts of solar and generator that can charge the battery bank.
One would think that when the system is charging and it’s only dumping in 10 amps via the generator it would show it’s nearly full on the SOC. But it always seems lower then expected.
So if anyone can please give me some ideas on what makes or ideas on what to change or make adjustments to I would appreciate It.
Thanks in advance. Crazy Marty.
