Good point, I need to add running the charger
equalisation cycle on a periodic basis to the operational procedures.
On a related note, the latest data showed a gradually declining state of charge, as the generator
was not being run long enough to give a full re-charge. Then one day, the voltage hit 13.2V, which is the default trigger to a reset of the state-of-charge, so it jumped to 100%. I'm not actually convinced the batteries
were fully charged at that point; a jump from 75% to 100% is a little suspicious.
And adding fuel
to the fire, I also have a SmartGauge connected, and the following day it was showing 70% state-of-charge, while the Victron was showing 95%.
Too much conflicting data.
On the good side, I found the temperature data...
