I rode the board in the makeshift state for close to 4 months because:
The time has come to finally bite the bullet.
First, more “metal > not metal” upgrades to the ESC enclosure. I replaced the bottom with an aluminum piece from a send-cut-send like service. It just needed a little of sanding and tapping the holes.
Drilled the deck to run wires through:
I took apart the battery and re-arranged it as follows:
There’s apparently a lot of unused space. I should be able to fit in 14 more cells by re-arranging from 12S5P to 16S4P. However, that would require redoing the P-groups and changing the ESCs, so I’m leaving that as future work.
I bolted several 3D printed parts to the deck that prevent the battery from moving side to side. I decided not to put any heatshrink on the battery since (1) it would be difficult to put on given the layout, and (2) I didn’t have any on hand anyway.
I have a layer of cardboard and foam between the battery and the enclosure. It’s thick enough exactly such that the enclosure gently presses against the battery to keep it in place but at the same time it doesn’t stress the wires.
The ESC case finally got a charge port. No more snapped hinges.
I decided to go for symmetry and put four 6355 Maytech motors. This is a bit of a downgrade in terms of power. Previously I had two 6385 and two 6355. On the other hand, the Maytechs are lighter and have a much better free-roll. This makes a big difference when I grab the front truck and pull the board around. Also the consumption is lower.
There’s still more than enough power for casual riding. Once the race season is back, I may swap for four 6385s.
I also put my second pair of Trampa wheels in the rear because symmetry is symmetry.
Wireless enclosure™!!!
And that’s about it! For now…
