Voicecoil's red, fully rigid commuter

Good looking battery box! How wide is it, and does it feel the same pedaling or do you have to compensate?

Hey Patrick,

The box is just a touch over 130mm wide. The Headway cells are 120mm wide without tabs and heatshrink so it's a snug fit!

Pedaling is not affected at all, I haven't spaced out the crank arms or anything either. I does feel odd if I put both feet on the ground. That's when the width of the pack is noticed but it rarely happens. When riding or stopped with one foot on the ground it's no problem.

What kind of temps are you getting on your motor now?

What kind of temps are you getting on your motor now?

I'm flirting with the devil and riding with 16-18A limited now (@72v lifepo4). Motor gets warm but not hand burning. I expect winding temps to be very high though.

Have not quantified it with a temp meter...yet, sorry.

after searching for ages, I finally have a grommet that fits perfectly around the wires that come in and out of the box. Trottle, Cycle Analyst, phase wires, hall sensors, and a positive DC pigtail from my battery pack (the 'key' of the system) all come out of that hole. Now they're sitting on rubber and water will have a hard time finding it's way in. The box has: one screw to pull the side cover off, one charge port on the right side, and the grommet'd hole for the wires. That's it, nice and neat.
