resetting the shunt

I’ve been running mid-SoC for a while so the battery and battery monitor shunt were no longer on the same page. FWIW, I think the monitor was closer to correct since it doesn’t use voltages to interpolate intermediate states of charge.¹

I spent a couple days getting the bank back to 100% for a calibration reset. Of the top of my head I think the last time it was full was in July when the bank was new. It’s weird having a bank that the solar array can’t fill at will.
