I think he has the cell count wrong. I determined 21 per module. This matches the multi tool data. So 6 parallel and 21 series 18650 cells per module and 4 modules per pack. Typical pack voltage of 3.6Vx21x4=302.4V. Current ratings sound reasonable. Also the LTC6803 multicell battery cell monitor only has two tnermister inputs. There are two per module or four cell temps per module. Multi tool appears to displays the thermal inputs as temp0-3 and LTC Temp 0 and 1 must be the LTC6803 IC temperature.
Anyway enjoy the show.
