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

    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...

    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..
