''The Reborn'' (IN PROGRESS) | FOCBox | 6473 200KV | 10s4p | First build

Welcome,

This is the build log for my first electric skateboard. I know there was another one but I took a completely different approach once I bought a crapload of parts from @cliofreak

To introduce myself first, my name is Flim. And in my spare time, I love to hang out with friends and do all kinds of activities! I got hooked onto e-boards when my friend bought a Meepo. I got to ride it a couple times and I soon decided I wanted one myself. I could have bought one (I mean come on the backfire ranger x1 looks freakin awesome especially for the price). But I eventually decided I wanted to build one myself.

So here it is, may I introduce you to The Reborn. Well, why this name lol. the boards uses a lot of used parts, thus the name ‘The Reborn’.

Why the chosen parts? Mostly because of the grande la grande buy from Cliofreak. I was originally planning to just go lipos and cheap motor, esc and stuff. But this deal was too tempting to pass :joy:. So I went with it. To not waste the great components I already had, I decided to go all out, stretch my budget as far as my pocket could go and get other decent parts too.

What I currently have: Longboard:

  • 90mm Flywheel clones + 80mm Slickrevolution
  • Caliber 2 trucks and bushings
  • Osprey deck (Stiff) + Fibreglass enclosure (Benclosures) with pre-drilled holes and hardware/gasket, including 10s LCD screen bonded in place

Electronics:

  • FOCBox
  • G2TB remote and transmitter
  • 10s4p Sanyo NCR18650GA
  • 6473 Alienpowersystems motor 200 KV
  • NEED 10s BMS I think 40/50 amps will do.

Alienware motor mount, clamp, and pulleys.

I got my battery yesterday. Still need to test it out.

I also managed to put together the drive train for the first time. However my wheel pulley keeps coming loose, so I need to find a way to let that stick.

Pictures will soon follow!

You need to put loctite on all bolts

It’s supposed to just slide in and it does, but it came loose 2 times today when I rode with it. So I guess I’ll get a small bolt to hold the wheel and pulley together

what’s holding it on the other side?

Nothing. That’s why I need to put in a bolt. I don’t know how the previous owner did this, he didn’t include this bolt. Of the 3 holes 2 of them have broken bolts in them unfortunately.

itd be better to have a retainer on the other side and then use nuts and bolts rather than just threading into the wheel

For the BMS I just used a ‘charge only’ system. Cheap eBay job. Generic 10s BMS. Re the pulley, the bolts on the AlienPowerSystem pulley sheared off and although I was tempted to drill out and rethread the wee legs of the pulley, I didn’t bother because it stayed in place fine when belt was tight. I mentioned that in my original sale. You could try putting electrical tape or heat shrink around the legs to ensure a tighter fit. I’d not drill into the wheel.

You didn’t have any problems with charge only? No drifting cells?

I had two packs fail on me on two different occasions. I swapped out the bms both times as all signs on here pointed to bad bms. However, I used the same cheap bms the 2nd time and it failed again. I know a bunch of guys on here that use charge only. I’d say, don’t cheap out on bms from my experience although charge only is quite common.

Tbh, there’s a chance I damaged them both during installation as I’ve just recently learned about the importance of connecting B- main wire first, then connect the balance wires. Well, I’ve discovered that info while building my 14s eBike.

need some advice on the bms guys

I’ve already decided to use bms for both charge and discharge.

So I can buy a bestech bms with e-switch, or just a bms and a anti spark switch. For the second option I would go with: https://www.ebay.nl/itm/37V-42V-10S-45A-Li-ion-Battery-Protection-Board-BMS-PCB-System-Over-Charge-Disch/162844447523 And http://electricskateboard.repair/index.php?id_product=36&controller=product

And for the first, I have been waiting for someone to sell me a bestech bms but so far no luck. I don’t want to buy 2.

Update:

Bms and charger just arrived.

Now there’s a prolem. My bms câbles are too wide, they don’t fit in the bms

So close, yet so far :joy::sweat_smile:

Update:

I broke my bestech bms… It sparked but I don’t know why or how…anyway I ordered a new bms and anti-spark switch

Now we play the waiting game…around 20 days…
