As the cells can output 20A current, you divide that number by the number of cells in paralell. Since you have a 10s3p where “p” stands for paralell, you can have 20 x 3 = 60A current.
An 18650 cell should be able to discharge down to 3.0 volts. Since it is 10 cells in series, that makes 3.0 x 10 = 30 volts. So cutoff start at 30.00 volts and cutoff end at 28.00 volts
Worth mentioning. If you have the cutoff at 30 volts, you will need to stop riding as soon as the cutoff starts, since going below 30 volts could be harmful to the cells. Maybe having the start at 31 volts would be better. I have it at 30 but I stop riding as soon as the cutoff begins.
If you use your cells’ full rated current output you will reduce their lifetime significantly and it will only boost your top speed by a tiny bit. That’s why I suggested 30A, or 10A per P-pack, which is plenty for most street skateboards
I’m trying to setup FOC mode, but It keeps on failing to detect hall sensors.
