    KT motor controllers -- Flexible OpenSource firmware for BMSBattery S/Kunteng KT motor controllers (0.25kW up to 5kW)

I managed to get one controller working correctly on one set of phase wires and halls with low power settings. Working on getting the...

    Building battery from MAKITA Konion PACK

    Thanks for the suggestions! I think i will be going with some 18650 sleeves or shrink wrap over the cells.. then using hot glue to hold everything. I doubt heat will be a issue with a 18p or 20p group of cells.. they will only ever see 20amp peak on a 20p group.. I don't want to use pl...

    Building battery from MAKITA Konion PACK

    Hey Everyone, I have thought about using 18650 holders to build my battery, however i would prefer to per say "glue" the cells together to build my 2 battery modules due to space limitation. I'm thinking 16 to 20p and each module at 10s. The parallel groups will be in horizontal orientation...

    Nyx frame, 273mm*40m V3 hub, and 650A

    I don't know the exact technical reason, but motor surpasses 100 degress +/- i start to feel my WOT launches slow down a bit... still fast.. but slower :roll: motor cools down, power is back up for the first couple WOT.. then repeats etc..
