You know if it is NOT, then you toast all those PMD.

Did you load test the batteries one at a time?
I have not load tested the batteries. At full charge during start testing, the start cycle appeared to operate at a similar rpm to previous good-start cycles.

PMDs were not mounted to any heatsink for the start testing. There is quite a bit of metal on the bottom plate, I'd think that's plenty of thermal mass for 15-20 second tests. None of the modules were even hot following testing. Is that out of the ordinary?
