use 22 gauge wire where possible
for HV DCDC-in, maybe 14? check peak currents
for HV solar, around 10-12 awg (the max you can to reduce resistance)
for HV motor & pack, use ~4 gauge wire in bay
TO-DO: figure out daisy chain controller board
ideally one terminating resistor pair in enclosure
only two CAN wires coming out instead of 4 otherwise
