I have had an EMAD 600W electric skateboard for the last 1.5 years. Have been happy with it but have been watching the developments of first the use of Li batteries and then smaller RC type motors in boosted boards and other manufactures so got me looking. Also me and my son are into RC cars so seemed like a good project to build my own.
First I found a set of wheels and trucks just like my emad board on ebay for cheap. This included a motor mount/belt so figured would make my life a little easier. Plus the big rubber wheels are nicer over rough roads and cracks. So figured let's do it.
My setup:
Motor: Turnigy Aerodrive SK3 - 6364-245kv
ESC: Hobbywing EZRUN-150A-PRO
Controller: Quanum 2.4Ghz 3ch Pistol Grip Tx & Rx System
Battery: Turnigy 5000mAh 6S 20C Lipo Pack
Wheel Pulley: 44T, 15mm/5mm
Motor Pulley: 18T from sdp-si
Got it all built and have a temp enclosure that is a tin I found around the house...works so far so good.
Now for comparisons between the two.
The EMAD as you would expect has few more features. Controller has settings to limit speeds at 3 levels for newbies. When remote is out of range it auto brakes. LED on top of board showing it's on and changes to red when battery is low. Braking function works quite well. However, the downside is the 3 SLA batteries which make it all quite heavy. 40 lbs total. Also on anything but a full charge has a harder time on hills. Top speed isn't bad (around 18) but think now since batteries getting older it has lost a few and maybe only doing 15ish. Again, thing with fresh batteries would be back to 18 and hills would be easier. Also can't swap batteries very easily and takes a couple of hours to charge.
The DIY, is faster for sure. Measured 22 on GPS. Also has more torque, when climbing hills but not as much on startup, sometimes give it a small kick. And is much lighter, 16lbs, so can easily cary it around when I get somewhere (while I used to have to roll the old one by just picking up the rear). Charges much faster and can easily swap out the battery.
Overall happy with the build and figure will continue to tinker with it...maybe go to regular skate trucks/wheels and make it extra light.
Thanks for all the help, have learned a lot from here and wouldn't have been able to build it with out of the work you guys have done.
