Hey there. I just hooked up a new system with two 170ah lifepo4 batteries (12v) with the Victron SmartShunt. The SmartShunt wants me to tell it the state of charge of the two batteries. How do I determine the SOC?
Is it really just a matter of looking at the battery voltage the smartshunt reports and cross referencing that with charts like this one:

My bank’s voltage is 13.27, so looking at the charge I guess my bank is at 77% SOC?
