So after reading many discussion on here I’ve decided to build my first electric skateboard and going all out first go!
I am planning on ordering 2 x enertion r-spec 2.0 brushless motors, space cell battery, 2 x DIY electric skateboard torqeboards 12S 120A car ESC OPTO HV, Wiireceiver with numchuck, 12S UBEC and 2 x motor mounts.
If someone could provide some feedback on this setup and if anyone has overcome the issue of only being able to go to 80% with the space cell before shorting out the ESCs it would be greatly appreciated
I will be sure to post my build once its complete.
Thanks for the reply lox897, yer I have some medium to steep grade hills in my area and way around 80kg. Do you think this setup will be able to handle going up hills? does it all depend on the gearing setup…
yes, it’s all in the gearing. This will be a beast with dual 63mm r-spec. Depending on your battery of choice 10/12s it will be a bit of a handful.
Unless you are a seriously talented rider, i might suggest easing into it with lower series batteries to start, then you can add more as you get more comfortable. 6-9-12s would be my suggested “learning” curve.
You can achieve the same effect by programming those ESCs to not be maxed out all the time. Dial the throttle output way down until you get used to it then tune it up some more when you’re ready. At least i think you can still do that on those ESCs when using a nunchuk. Anyway it would save you money on batteries.
I currently have a space cell, torqueboard’s esc, and single enertion r-spec setup like @lox897 said.
Unfortunately, I haven’t been able to solve the 80% problem, even though I live in a completely flat area…
settings I am using:
My acceleration is set to the lowest setting (which surprisingly, is actually pretty quick).
max forward: 80%
no reverse, 80% braking (a lot of braking when you slam on it, but I like being able to stop on a dime just incase…)
motor timing is also at the lowest setting, which makes the overall speed slower, but cuts down on amp draw.
basically, the problem is the space cell’s max of 60 amps; it isn’t a bad thing, just torqueboard’s esc is a beast, and was designed to pull more than the space cell can handle. tons of people use it with lipo’s of a higher discharge rate without a problem.
Solution to the 80%!!!
Buy a VESC instead! not bashing torqueboard’s esc, it really is awesome and easy to program; just for the space cell, a VESC is way better. Also keep in mind that all my settings are set up for my weight (140ish pounds, 65kg) on 14/36 gearing. I have also tried 13/36, and 16/36, but the middle ground worked best for me.
When my dad took my board for a spin, he blew the space cell’s fuse (standard automotive fuse; cheap, and easy to replace) within 5 seconds of riding it… he weighs about 200ish pounds, 95kg).
You’re right, I’m using the space cell with two VESCs and since you can limit battery values to 60A and still put the values for the motors higher (like 2x 80A), it never blows the fuse. Also, I’m able to climb steep hills without any issues, even with hub motors which are quite demanding for power usually.
Thanks for the help everyone. So just starting looking into the VESC and it seems like a much more efficient setup and a lot more features without the risk of blowing a fuse. Just to clarify if i purchase 2 x VESC will i still require a UBEC and wiireceiver?
@kai In order to make the “E-board Builds” category really easy to search & locate specific builds i am asking that you change your title to something descriptive that better expresses the makeup of your build.
Most of the new build threads tend to end up with a name such as
"new- noob - noobie - beginner - first - build - help - newb" this becomes hard to keep track of.
I would like to see each build thread with a descriptive title, such as;
Project Name | Deck Name | Trucks | Motor type | Mounting method | Voltage/Battery | ESC
Example
The Samurai | Custom Deck | Paris Trucks | R-SPEC | Custom Mount | 10S | VESC
It’s a Rayne Mosquito II, with 83mm flywheels, dual CarvOn hub motors V2, Enertion Space Cell, dual VESC and a Nunchuk remote. Max. speed is 68kph with 83mm and its around 90kph with the 90mm wheels. I’ve never had difficulties with hills so far, but starting from a standstill wont work if it’s more then 10-12%. I am about 72kg so I don’t know how it would perform if somebody is around 100kg, but I usually tow my kids also uphill and nothing happens if I approach that hill in slow speed.
It’s really difficult to give an advice since people tend to have different requirements. I wouldn’t recommend hub motors for those steep hills around 25%, not because it’s not possible, but it’s might be no fun longterm if the motors are pushed to their limits in low ERPM all the time.
But think it would be quite easy to sell that board again if you’re not happy with it.
