I just picked up a Tenergy (GT Power) watt meter from Amazon to try and diagnose sine issues I’ve been having, and want to mount it somewhere that I can see it while riding. I’d like to mount the meter on top of the deck at the front truck, and run 10 gauge wire to the battery and ESC from the unit which would be ~18" of wire for the source and load sides of unit. I know we are supposed to keep the battery leads as short as possible, and the unit comes with about 3" of 12 gauge wire on either side, but for testing purposes, would running a 30-36’ loop of cable with 5.5mm bullets from the battery through the watt meter, and back to the ESC cause significant issues with performance, resistance, or accuracy of readings?
Feel free to share your live current/voltage/watt meter setup, if you have one. Even better, if you have a setup that supports datalogging, that would be even better!
