I have a SmartSolar MPPT 150/85 charge controller powering a bank of 5 x 100Ah LiFePO4 batteries.
My batteries are charging everyday and reaching 100% (14.4v). I am able to manually sync the BMV at this point to show SOC 100%. However, after a few days the system 'learns' and corrects the SOC and always shows 0% even when in the high 13v range.
I've tried dropping the charged level to 14.2 as suggested in the manual and changed the charge time to 10 mins but my BMV won't learn correctly.
Any help or thoughts?
