My first DIY build đź–¤

This thing was a pain in the ass, but was worth it!

12s8p 30Q from @Chibatterysystems
TB40 deck from @torqueboards
Sick ass enclosure from @BigBen
Torque6 ESCs @torqueboards
TB 6380 190kvs
50D torqueboard baseplates with 270 hangars from @Boardnamics
8” MBS tires
Rockstar2 hubs @MBS
62t wheel pulley

18t/62t
~50mph

Will definitely go to a 15t motor pulley to get some more torque. Definitely don’t need that top speed.

Overall happy with this one!

Let me know how she rides and if you get any wheel bite? :sunglasses: FOR SCIENCE :call_me_hand:

I don’t see any fishpaper between p-groups on that battery, which worries the fuck outta me

Nice build though!

That was just the first step, it turned out like this :blush:

Are you saying that @Chibatterysystems, after taking that first picture picture, took off all the tape, added fish-paper, and then put fiberglass tape back on?

I’m specifically talking about the lack of fishpaper in these places:

(Sorry for the criticism, I’m just making sure your house doesn’t burn up)

Should be fine but did you use ring insulators? I think more important as I had a battery that shorted not using one. But i used 21700 cells and they didn’t start a fire, just two cells died but my battery pack still had voltage. I think 21700 designed that way

siiick build bruh.

The lack of fish paper between p groups is not dangerous.

So what happens if the wrap between cells belonging to neighbouring p groups fails due to vibration induced friction?

Why would it fail? This is standard building practice. We’ve never had a failure.

I see you’ve edited your comment,

They will not experience friction as they’re glued together and taped.

The same reason we use ring insulators on the positive terminal.
Esk8s have a lot of vibrations and can degrade a battery in various ways.
Better safe than sorry.
We would not be having this discussion if we were talking about a static or low vibration application.

The groups are extremely well secured with other methods. If there was ever a reason to do it (even a single failure in the many years) I would implement that in my build method.

Thank you for your feedback

Failures due short circuit between p group have happened. Maybe not in one of your packs but they have.
As far as I am concerned it is a simple additional safety measure and I see no reason not to do it.

I see your point of view and it’s certainly good for extra safety. If there was ever even a sign of that problem in my batteries then I would have implemented that in my batteries.

Sorry op for the slight derail. But I just wanted to say that while I would personally use fishpaper between P groups and recommend everyone else to do so because it adds to reducing possible shorts with very little extra work (literally just cutting it to size), I can attest to @Chibatterysystems’s expertise. Out of the hundreds and possibly even thousands of packs he’s built, I don’t believe he’s had any error on his part. I’m not sure what percentage of the packs he’s built is for onewheels, but no one has had a failure in his onewheel battery mods and I can argue that most onewheels get a little more abused than an esk8.

Thank you for that. I’ve certainly made minor mistakes in the past and there is no dodging that but I strive for the highest quality and safest batteries. My build method is refined from years of building and customer feedback.

I think we can all tear each other apart AFTER one of the packs catches on fire.
