update: I did one more run before dark. Sampling rate was every .2 second. Current limit set to 13 amps.

This time the lowest voltage under load reached down to 11.23v, but just once early in the run. After that, the voltage didn't drop below 12 volts.


I knew voltage dropped under load, but I'm a bit surprised that it is dropping this much. And the LVC didn't seem to affect this voltage drop under load.


My other observation is that the current limit does not do what I always thought it did or was supposed to do. If the current limit limited the amps the motor could draw, then I would see less of a voltage fluctuation the lower it is set. But there was no difference in voltage fluctuation between a 30 and 13 setting, which means that the motor was still drawing the same amount of current.

Only observed difference was that at the 13 setting, it took more throttle to get the truck to move, like there was a crazy amount of expo on my radio.
