Hey Kevin, I'm trying to build one of these on my own, looks like a fun project. I do have a couple questions, first, how much were those batteries, and second can I use 12v car batteries for them, and third what was the overall amount you paid for the motor, batteries, and ecu? Thanks.,
@Kevin.OBrien44
@Kevin.OBrien44 Год назад
the batteries were about 200 i think. 12 is probably too low of a voltage if you want to go faster than 10 mph. probably around 600$

Does the belt ever slip or run off track? Everytime I deal with them, they always find their way off track.
@Kevin.OBrien44
@Kevin.OBrien44 Год назад
that’s why i went with one so thick. so it wouldn’t do that. i actually had it slip so i checked it and the motor bent my 1/4 in thick steel motor mount. so the belt is just fine for now
