Connected up the SOC output to the fuel sender. With a bit of calibration (and a 470ohm resistor)…. Voila! Full = Fully charged.

Cleaned all terminals and bus bars… now all cells above 3.09v during 160A test run. Well except cell 26… pesky thing… cleaned again just for good measure, too late tonight for another test run. Will try full scale test in the morning, when I drive to work!

Fixed a minor BMS issue cell 26, was causing bank C to report only 2 cells. Replaced the cell board. All 12 reporting in correctly. Still finding "rtv" under the bus bars. Only another 20 to check…
