48v flooded deepcycle battery is at 48 volts but CCGX SOC reads 70%.

Hi all!

Helios hasn't been out in a while and my 48v 1160ah flooded deep-cycle battery is at 48 volts but CCGX SOC reads 70%. The Multi will blink red on low battery if voltage drops more than 48v, which is normal given the low voltage, however, shouldn't it read 20% SOC instead of 70%? This almost made me think that it was OK because I was just checking the CCGX SOC and didn't really pay attention to the voltage until I checked the Multi and saw the red indicator. Is this normal? What do I need to modify in my settings to get this right? And should I make those changed through the CCGX or through the ethernet adapter? Thanks to anyone that can help.

Hi @Funkaddict

What do you use as battery monitor? a BMV or the Multi?

Obviously the capacity of the battery is not what you configured it to.
