Does the BMV-7xx's "Temperature Coefficient" setting just improve SOC readings, or in a networked configuration does it also have some influence on a Solar MPPT and it's "Temperature Compensation" setting?
For Lithium batteries, the recommendation seems to be BMV Temperature Coefficient = 0.9% cap/F and MPPT Temperature Compensation = Disabled. I was just wanting to make sure a BMV Coefficient setting will not override a MPPT Compensation setting.
Thanks,

Hi @siletzspey,
the BMV temperature coefficient setting affects only battery capacity in relation to temperature below 20°C and does not influence compensation on a MPPT. The higher the temperature, the more battery capacity.
Below 20°C battery capacity starts to decrease.
MPPT temperature coefficient directly affects voltage compensation during charging. For LiFePO4 this should be set to zero. No compensation.
