nice work, allot to read through, i am planning on the same, with some other mods

for acceleration, my solution is a super capacitor, charged off the regen, to give a short boost of current when needed - unfortunately my capacitors are in a back log somewhere in China

does the Kelly controller offer a way to control the current draw while running, maybe via a digital input? (big red button on the dash board lol)

the mod potential for TS is amazing 😁 i hope to put a new motor (and try) and pass dvla hurdles over summer
