####UPDATE NO.1: post #9
####ORIGINAL FIRST POST:
after being inspired by casey and terrified by the price of a boosted board, i decided to build my own electric skateboard. being a student on a budget, i want to keep the costs down. however, i figured that saving on the electric components is not the brightest idea. i will try to save money on the skateboard parts. this means, that i will borrow the deck, trucks, wheels, and bearings from a friend of mine and if everything works out well, i will eventually buy my own stuff. that way i can minimize the financial risk and still get a good board. so far, i’ve done quite a lot of reading and came up with the following parts:
-VESC 4.12 -Turnigy SK3 6374 192kv -Benchwheel remote -2x Turnigy or Turnigy 5S 5000mAh 20C battery in series -15:36 transition on a 15mm belt -90mm flywheel clones (the wheels i will borrow are 76mm or at least they used to be, they are a lot smaller now) -Caliber II 50° Trucks
i already ordered the VESC and the motor pulley and am in the process of building the motor mount.
actually, i didn’t want to spam this great board with another first-build-advice-seeking thread, but i couldn’t justify spending all the money without having someone at least taking a brief look at my part list. if you want to, i will try to convert this thread and document the build as soon as i get all the parts and enough time to build the board.
two further question regarding the c-rating. the theoretical max discharge of the battery would be 100A. regarding the specs on hobbyking.com, the motor has a max current of 80A.
- should i limit the current in the VESC’s settings to 80A?
- what would happen, if the VESC/motor pull more than the max 100A? does the c-rating mean, that the battery will limit the current to the 100A (in this case) or is it more like that the battery can supply more than the 100A, but going above this value will damage the battery?
