Based on Victron "mppt-solarchargers" white paper: "The configured coefficient is in mV per degree Celsius for the whole battery bank, not per cell".
If my battery bank is wired at 48Vdc (Lead Acid) by one string of 8 batteries, 6 volt each (3 cells), -0.005mV per 2V cell/ºC (per manufacturer) would it be -0.12mV/ºC the right value to set here?
If this compensation occurs automatically, why the system allows you to choose between a positive or negative value?
thx!
