Hi. I’m planning to build my first e-skateboard for commuting. Goals: Around 10 miles range. Top speed 20mph Need to do up-hills like 20% gradient. My weight is 80kg and some back pack that will be like 95kg. Speed and up hill power is priority rather than range. Low budget, simple, without fancy look. I live in Australia so some Chinese online store count in like AliExpress or eBay etc. This is my part list. All in US Dollars Long board 38in standard board $32.00 https://www.kmart.com.au/product/38in.-free-rider-skateboard/1970301?&gclid=EAIaIQobChMIteusgcqy3wIVESUrCh3Ghw3BEAkYASABEgKKPfD_BwE&gclsrc=aw.ds Motor 200kv, 2300w, 6S~12S/22.2v~44.4v, 63mmx54mm $64.00 If I can believe this spec it’s a good motor for this price. Two Batteries Same like with the motor specifications looks good for this price. 5S 18.5V 5000mAh 30C Max 60C $53.00 each 90mm Wheels $22.00 Trucks 180mm Caliber $24.00 VESC Controller $100.00 https://ebay.us/A18tDn Mini remote Controller With Receiver $32.00 Motor mount and belts, gear ect. $35.00 Battery charger $29.00 Other small parts: $25.00 Battery connector, Bearings and spacers, Riser Pads etc.
I’ll use Loop Key as a switch off/on solution. I won’t use any BMS for now just take batteries out for charging.
Probably I can save like $80 by buying smaller batteries (like two 5000mah 3s batteries) and motor but I’m not sure it’s going to work with my top speed and up hill goal. This motor from above I think regards to spec is good configuration with 10s 5000mah batteries. From this batteries I’ll get roughly 42v = 200kv - 10s. The motor from the link has 200kv. I can save like $50 on VESC by buying ESC but I’m not sure if it’s worth it. It might be better to buy two half power motors rather than one big one but I’ll cost $50 more because of the mounts, shipping, price etc. Dual motor on VESC will cost me like $100 more so not now maybe later.
How will you rate this setup. What do you think? Thanks.
