I'm back with my last electric longboard I ever gonna build!
This time the Boosted Mini really inspired me.
I wanted to build a commuter board with a kicktail and dual hubmotors with enough range and speed.
This time no more Lipo's because I bougth a spotwelder and used 27100 cells.
I saw a lot of good reviews from the brand Ownboard and bought replaceable hubmotors, esc and their remote.
They are not the most powerful hubmotors you can get on the market, but they are perfectly fine for me.
The hubmotors max speed is 42km/h (tested and it's true) and with my 10S2P samsung 40T battery I get a range between 18-25km! I live in a flat area and got only bridges which are no problems for the motors, then can go up to 20% hills.
I used a special bms in this build, it has bluetooth and the battery can be monitored by your smartphone!
I spent around 650€ for this build so I'm sure that's a good price for what you finaly get.
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Collect All the Parts You Need
Ownboard kit (without battery)
This kit is amazing, it includes everything you need without a deck and battery.
Charger, griptape, bolts, bearings, bumpers, red light, silicon wire, xt60 connector,... just everything is inlcuded and of course the motors, esc and remote.
I would really like to make my own battery with a bluetooth bms so I could easy check my battery status.
This kit also comes with enclosures but I didn't need them so I sold them.
I chose for a small deck with a kicktail, I just like the looks of this cruiser decks and the kicktail is so much fun. It's a very stiff deck so it has no flex at all.
Samsung 40T 21700 Cells:Nkon
I bought 20 of these to make a 10S2P battery pack (37V 8Ah 296Wh)
This would give me a range of minimum 18km.
60A 10S Bluetooth BMS:Aliexpress
This BMS looks amazing, 60A more than enough because the esc only pulls max 24A. You can install an app on your smartphone (Android only) and check so much parameters, logs, settings,...
You can also connect it to your PC for even more settings.

Step 2: Spotwelding and Soldering the Electric Parts
In this part we gonna make the 10S2P battery:
To be clear I used a stiff deck so I this pack won't need to be able to flex!
We bought a spotwelder to make a nice and clean looking pack, spotwelding is so much better for those cells than soldering. Soldering will heat up the cells which is bad for them.
First lay 10 cells next to each other and put glue in between.
Now it's time to start spotwelding, make sure you make a layout for your nickel strips, I always do 2 welds per cell (So you will see 4 welding dots on each cell).
After this connect the BMS to the battery, I used the bms also for discharging so add the silicon wires to the BMS and connect the output silicon wires with an XT60 connector so it can be plugged into the ESC.
Connect the charging plugs I mentioned before and the pack is almost ready!
Put the heatshrink around the batteries, It's just the same as the small heatshrink for wires. I used a hair dryer to shrink the plastic wrap.
The battery part is done, let's go to the next step.
Step 3: Put Everything Together
Making the enclosure
I used a sheet of plastic to make this enclosure. I used a hair dryer to form the enclore to the correct size.
I used 2 sheets and glued them together.
After this I glued the ESC and the Battery pack in the right position. I did use a lot of glue for the battery, to make sure it won't come loose after some hard rides. In the picture you can see only a bit of glue, I used much more after it! also add glue to the sides of the pack. It's a heavy pack and it will vibrate a lot!
Easy to access
I 3D printed a piece to hide the switch, charging port and motor connector wires.
Drill holes trough the deck to attach the side rails which will hold the enlosure.
That's it guys!
Step 4: Pictures of My Final Creation
I really like this build!
Never had problems until now, I have ridden for like 800km and it's just so much fun! The battery has like almost no voltage sag (max 2V) because the esc only pulls 24A which is no problem at all for the batteries.
This was my build, hope you guys enjoyed it!
