Hi everyone!

I decided to make an electric longboard this year. Boosted Board has inspired me and it's such a nice electric longboard, but so expensive (like 1500€ for the 2000W model).

Before I start I will explain some things because I didn't really want to copy the Boosted Board design.

First of all, I wanted to make an Electric longboard as thin as possible, so I used separate Lipo cells and made a very thin battery pack (12mm) so people won't see it from the side that it's an Electric longboard.

The second thing is the power, I would like a longboard with a power between 1500W-2000W, The motor can handle 2220W but I use a 6S battery so the power will be a bit lower like 2000W max peak but that's really enough, trust me ;)

The other reason why I use a 6S battery is because once you go higher than 6S the price of the ESC is so much higher like double the price for 8S or 10S, Also charging a 6S battery is much more easy than a 10S.

If we talk about speed, I theoretically calculated the board at about 46km/h so I would practically reach about 40km/h. And in reality I have tested it on the smoothest road in our town and I can ride 42km/h max speed.

So on the most roads I can perfectly reach 40km/h which is really so amazingly fast.

The battery with 220Wh will give me a 14km ride.

The longboard I ride for a while is a Madrid Weezer and it isn't an expensive board (only 100€) but it has a bit of the looks of a boosted board.

In total I have spent like 300€ for every single part (except the longboard itself) to convert my longboard into an Electric longboard

I think you know enough information to start the explanation how I made my Electric longboard.


! Video's coming soon so stay tuned by this instructable or my youtube channel !

Step 1: Collect All the Parts You Need

What do we need?

SK3 - 320Kv Motor: Hobbyking

You can use other motors too but I have calculated the speed and torque on this motor and it is the most powerfull in the 50mm diameter series and not very expensive (52€)

120A ESC: Hobbyking

This is a boat ESC and runs very smooth with no problems. You can also buy a program card for this ESC which I also did. You can change several things like acceleration, brake, cut off voltage,... -> Hobbyking

Lipo Batteries:Hobbyking

I bought 12 cells of these, so I can make a 6S2P battery pack, the cells are 5000mAh so a 6S2P will give me 22.2V and 10000mAh, enough to have fun long ride.

Another alternative to get a slim battery pack is this Multistar 6S 10Ah pack which you can disassemble, Here's a link how it looks like.

Transmitter and Receiver:Hobbyking

I used this controller because there are used a lot for electric longboards and there's a 3D printed version available which only has a throttle because you don't need a steering wheel on a longboard controller. BadWolf GT2B Case

So you need to unscrew the original controller and place all electrical components in the 3D printed model which is much more smaller. -> Step by step explaination

6S lipo charger:Hobbyking

Very nice charger 250W 10A so it will charge my battery in 1 hour! I know in the picture you can see I bought another charger but it's only 50W 5A charger, it was a very cheap one but it takes 5 hours to fully charge the battery so the 250W charger will be my next upgrade.

XT60 Connectors:Hobbyking

Very good connectors and the have a small lock which never came loose during a ride.

4mm Bullet connector:Ebay

this is to connect the ESC to the motor (ESC has standard no connectors so you need to solder them)

6S balance charger cable:Ebay

To charge the lipo battery pack you need 6S charging wire, this will balance and charge every cell perfectly.

Metal timing pulley 30T:Ebay

This is a 30 teeth pulley, 16mm wide (HTD5M serie)

(btw why buying expensive pulleys and belts on special sites like sdp/si when you also find them very cheap on ebay, but I have to say I had searched so fu*king much until I finally found the pulleys I needed)

Metal timing pulley 15T:Ebay

This is a 15 teeth pulley and has a 6mm bore which fits perfect on the motor shaft. (HTD5M serie)

Rubber timing belt 54T:Ebay

I bought 5 of these because if one should break I have some extra but until now no problems with my first belt!

If you want to calculate the center distance and other stuff very quickly -> Pulley/Belt Calculator (HTD5M serie)

Silicon Wire:Ebay

You will need silicon wire to make your battery, this wire is very flex and can resist high temperatures so if you solder your wires the isolation won't melt. I used 10AWG but 12AWG is a bit smaller in diameter and will also be enough, so just saying I'm using pretty big wires but they won't overheat.

Longboard Madrid Weezer:EuroSkate

Make an aluminium motor Mount: Download my inventor design

Rubber sheet like 1mm thick

Bolts and Nuts

<p>What do you think about this type of hub motor?</p><p>https://www.cafr.ebay.ca/itm/262574219922</p>
If you really want hub motors, I can recommand these:<br>- Dual Hub Motor (130kV 6S)<br>http://diyelectricskateboard.com/diy-electric-skateboard-kits-parts/electric-skateboard-hub-motor-dual/<br>- Single Hub Motor (130kV 6S)<br>http://diyelectricskateboard.com/diy-electric-skateboard-kits-parts/electric-skateboard-hub-motor-single/<br><br>It's a good brand and you can buy new wheels for the hub motors wheels:<br>http://diyelectricskateboard.com/diy-electric-skateboard-kits-parts/hub-motor-replacement-wheel/<br><br>The 83mm wheels will go 40km/h<br>The 90mm wheels will go 45km/h<br>If you use a single hub I should use the 83mm wheels (it has more torque with 83mm then 90mm)<br>When you want Dual hubs you can choose 83mm or 90mm, will both work fine ;)
<p>merci beaucoup!</p>
It's very nice and clean looking with hub motors, but I can't find the ''kV'' rating in the discription on ebay?<br>I guess like 110kV but you need that to calculate your max speed of the board. They are also pretty expensive? (300$)<br>And if they are 110kV you need 8S to go 40km/h.<br>When you use 6S you won't hit 30km/h.<br>ESC's above 6S are much more expensive (like 100$ for an ESC 8-12S)<br>This one has 2 hubmotors so you will need 2 esc's (200$)<br>And then you also need a battery and a controller (150$)<br>Only 650$ for this and believe me you need a lot more like chargers, wires, and stuff so...<br>And what if the wheels are old, can you buy new for hub motors? I don't know :)<br><br>I like the normal motor setup with pulleys and a belt because you can choose the speed depending on the transmission.
<p>Merci!</p>
Can I solder them directly after I bought them or do I need to first discharge the batteries or do something?
<p>You can directly solder them after you bought them ;)</p>
<p>Do I need first to charge the batteries before I solder them?</p>
Nowp the balance charger will do this ;)
<p>Hello there!</p><p>First off, just wanted to say your build looks super clean, well done!</p><p><br>I was wondering about some of the specific specs, if you happen know them.</p><p>Top speed seems to be 40 kph correct? Or around 25 mph. How far will it go though?</p><p>Also, I noticed you doubled up on buying the ESCs, controllers, motors, and so on. Just curious, who got the other board?</p>
But now I have sold mine and I'm making a new one with a slightly better ESC and faster charging
Hi man and Thanks!<br>The range I could get was like 15km.<br>My friend also wanted to make a esk8 so that's why I have everything double ;)
<p>Hi, great guide! I just made my own board with the same parts you used, but my braking won't work. The board can go forward perfectly, but no matter how I program the esc I cannot stop the board. How did you get your braking to work?</p>
Hi, you have the esc programcard? just pull the triger in the opposite direction while riding forward and the board will brake.<br>Do you have set the braking ''%'' ? maybe it's on 25% and it is just so weak that you can barely feel it, so you can try putting it on 50%
<p>Ok tank you for everything :)</p>
Hi again, i found a power supply at my home and I would ask if it is compatible with the 50W charger you use?<br>
That's really perfect!
<p>Hi, the motor that you put in the description isn't in stock on Hobbyking.com do you know an other website to buy this motor or do you have an idea for an other motor who is compatible with this setup?</p>
I don't know another place to buy but I should use this one: https://hobbyking.com/en_us/turnigy-aerodrive-sk3-5055-280kv-brushless-outrunner-motor.html<br>Higher torque and topspeed with the same setup will be like 38kmh.
<p>And is this power supply: https://hobbyking.com/de_de/hobbyking-105w-15v-7a-switching-dc-power-supply.html compatible with this charger: https://hobbyking.com/de_de/turnigy-b6-compact-50w-5a-automatic-balance-charger-2-6s-lipoly.html ?</p>
Its ok to use Alien 5065 Outrunner brushless motor 350KV 2200W?
Yep that's no problem, but think about the max speed which will be like 45kmh, but maybe you want a high topspeed ;)
<p>Bartroosen, ik wil graag dezelfde motor gebruiken als jou ,maar die is niet verkrijgbaar meer :( weet jij mis een motor die ong dezelfde specs heeft? </p>
Ja er zijn nog enkele die ongeveer dezelfde specs en prijs hebben en die zelfs beter zijn voeg ma anders toe op facebook -&gt; Bart Roosen
Thx zal ik doen
<p>Bartroosen, mooi board ik wil ook en electric longboard maken! Jou pagina heeft me veel geholpen. Heb je mis nog tips? Of probemen waar je tegen aan liep? </p>
Er zijn wel een paar dingen die ik zou veranderen maar dan kan ik u misschien beter bereiken via facebook?<br>dan kan ik mijn tips die ik heb wel meedelen met u
<p>Hello,</p><p>for the charger how do you connect the charger to the electricity?</p>
I use a 12V 5A power supply but you just need power supply of 50W or more and a voltage between 12-16V i guess, but it's in the discription of the lipo charger ;)
<p>Hello, just a last question :)</p><p>Is this right?</p>
<p>No problem ;) and yep, that's correct</p>
Thanks very much for your help!
Thabk you,<br><br>But when I chareg the battery I need to connect only the balance cable to the charger or also the XT60 battery cable?
Yep I need to connect both to charge it
Thank you!
<p>Hi, very nice project!</p><p>I'm trying to do one this because we need to make a project in the college.</p><p>I have just a few questions:</p><p>-Can you maybe explain a little bit better (because I d'on't understand it) how to connect the charging cable to the batteries?</p><p>-The links of the parts aren't working. Can you put the res links please?</p><p>Thank you for this awesome project!</p>
Thanks man!<br>Well I have a picture wich will make clear how to connect the balance cables to a 5S pack, so it will be in the same way as a 6S pack ;)<br>For the links, you need to dissable adblock and then open them, wait 5 seconds and 'skip ad' right above in the corner.
Very nice build! I hope to try to copy parts of it when I have more time. <br>Just one question, why do you have two motors in the pictures? You only used one right?
Thanks!<br>Yes I only used the 320kV motor ;)<br>The other 236kV motor was delivered wrong but is also a very good motor.
<p>Nice instructions! Made it with the same components, and I must say that the board performes awesome! What ESC settings do you recommend? Also, would there be a way to make the controller more compact? Thanks!</p>
<p>very nice! So if I wanted to get 30km range would I just double the battieries into a 6S4P?</p>
Yes you can do that, but you can also change the transmission or use a lower kv motor (my type has 3 versions 236kv, 275kv and 320kv) so the topspeed will be lower and the motor will have more torque so will consume less power ;)
<p>Hey sweet board! If you are not already, join us on the eskate forum! We love to improve our electric skateboards and share ideas! </p><p><a href="http://www.electric-skateboard.builders/" rel="nofollow">http://www.electric-skateboard.builders/</a></p>
Thanks man!<br>I will take a look on it!
<p>Hi, how did you connect the balance charger cable to the batterypack?</p>
Hi,<br>I have made a kind of extended cable for the charger so I can plug it more easy into the board.
<p>Thanks! And does that cable go in the batterypack?</p>
Yep underneed the rubber is the balance port of the battery pack, so it is a little bit protected for water.
Hey man I was wondering if you would make one for me I'm not really good with electrical stuff and I feel I would do it wrong maybe we can exchange some info and see if you can do it for me I would greatly appreciate it
<p>Hello Bartroosen, I really like your electric skateboard build and I want to make one, before starting I have a few questions;</p><p>1.- You are using a boat esc, I had read that kind of ESC's can only go forward, if this is true, How do you brake?</p><p>2.- The motor that you link to this instructable is 320kv, I had read that the maximun recommendable for electric skateboards is 270kv because if you use higher Kv's you will not have enough torque to climb a incline, How it's working on your electric skateboard? Can you climb high inclines?</p><p>3.- The motor that I talked before needs 10s if you use a 6S2P you are using the 60% of the motor capabilities, Did you notice any problem with this?</p><p>4.- Talking about battery, are you using BMS circuit to be safe and dont have problems charging the cells equally?</p><p>Best regards</p>
