palmermd wrote:According to the manual you can take the readings anytime, and the maximum allowed variation is based on the current total pack voltage:Code: Select all
Total voltage (V) Approx. 360 Approx. 380 Approx. 390
Max - Min voltage (mV) 230 140 135
so at 373 volts you would have had to had a variation more than 140mV in order to be out of spec. 23mV is pretty well balanced.

Actually, it appears that the dealership only replaced one module (module #29). Each module contains four cells: two parallel pairs in series.BiggieJohn wrote:I didnt have leafspy right away, so no pics of what the situation was, but I took it to my local dealer and Nissan had him tear the battery down to replace 2 modules.
