Just finished my build. The goal of this was to make the cheapest functional build possible with a BMS to take me to work and back. It is a 10km trip with a decent incline. I really don’t think that a build can be done much cheaper than this with Li-Ion and BMS. I also wanted to try building a tubular skateboard frame and then enclose the electronics inside.
Anyways here is the build cost in case anyone is interested:
- 190KV motor - $43
- 6S2P Basen 26650 batteries - $50
- Hobby King X-Car 120A ESC - $60
- Motor Mount from @korryh - $40
- Mini Remote - $35
- 6S 60A BMS - $16
- Battery Indicator - $4
- 60A Breaker Swtich - $7
- Caliber Trucks - $38
- 83mm wheels - $27
- 15T pulley - $4
- 40T pulley - $14
- 15mm belt - $7
- 6s laptop style charger - $15
Total cost $360
The deck is made of some 20 year old plywood that I found lying around and the frame is made of some 1" round and 3/4" tubular steel that I had lying around as well.
I’ve only ridden it 6km to work so far this morning, so not much specifics to report on yet. Didn’t even have time to change the settings on the ESC before riding as I just finished it last night.
Will report back on range and top speed soon.
