Re: Did I read <R32> Correctly? Six CIMs?

CIM motors stall at at 133 amps, PROVIDED that the battery can provide 133 amps. We discovered in 2010, when we had two CIMs and one FP in each transmission, that under load, the battery sags way down, and cannot provide more than about 95 amps. With a fully charged, brand new battery, we could, on very rare occasions, blow the breaker, but once a battery had a few charge/discharge cycles, it wouldn't provide enough current to blow the breaker, even with all drive motors stalled. We actually got more torque by removing the FP from the drivetrain because the battery didn't sag as much.
