Power Monitor

So the power monitor I purchased is rated up to 100A peak/50A continuous. It definitely comes with 14 gauge wire, which is rated at 20 amps continuous, and is therefore quite thin for such high current:

So what's any engineer going to do in this situation?

Crack the case open and solder on some bigger leads!!!

No, your eyes are not fooled, I only gauged down the negative leads; the positive lead is only for power and a voltage measurement, which equals very low current. I'm not sure why the designer of this board decided to place the current resistor on the negative lead, but hey, why the hell not? Two different ground potentials probably won't make any difference on this board. On an NI board, this is a big no-no, but "this isn't a high precision device by any means, so fuck it" is probably what the pcb designer thought right as he spec'd out a 14 gauge cable for his '50A continuous' device.

So here's the unit with the case hacked around the huge leads:

I plan on mounting this right on the top tube underneath my seat so I can look down to make sure I'm not overcurrenting the motor too long. Keep in mind my motor controller can pump out 2800 watts, which is well over the motor's continuous rated capacity.
