yep will do

will just have to do balance leads well

watched a few of leewrights vids about them and learnt a lot and def gonna try to get this one right

need to order a new connector for the balance leads though
anyone know what jst type it is? ph?

@ZachTetra

you get a bit more forgiveness with the silicone sheathing, a ‘checkpoint’ once you get a single wire, and its much safer overall

Lol yah

the braid is not easy to solder and manage when compared to the wires

Found this on https://onewheelrider.eu/

lil scary

what do you guys think?

Also is that duct tape…?

Aftermarket onewheel packs are, as a whole, are horrifyingly low quality compared to the packs most builders on here build/sell. Even the most reputable builders of OW packs still do things very frowned upon with the packs we produce. If that’s a market you want to jump into with your battery building venture, the competition would benefit everyone to build safer and more price competitive packs.

I’m curious what you think, currently on the fence of getting VTC5A for my next pack. They have less power density than VTC6, less internal resistance, also seem more reliable. Downside is ofcourse 400mah less capacity, which is fine I think.

[JoeyZ5]

I’m already looking into it…

I did a lot of research last week and Chi makes a shit ton of money on their packs

At this point I’m 95% sure how to build packs like theirs and sell them at a price like 15-20% less and still make a good amount of $$$

With safer build quality - I’m not going to be cutting any corners at all

Here’s this and a thread with some info if you haven’t found it already:

ISO Battery Builders for OneWheel XR specifically

For anyone else’s use. I’m not planning on getting into the one wheel battery game, so I haven’t verified this myself, but this reddit link is probably going to be useful to someone around here. Battery Schematics

[JoeyZ5]

Yeah I’ve been all through that thread, along with some OW reddit, facebook, discord, and more

[JoeyZ5]

Currently members of the OW discord are working on pulling the FW off the BMS to fix battery upgrade capacity issues. It’s definitely possible as the onewheelrider.eu websites sells FW adjustements for ~$120 bucks!

Just had a little spark is it safe to say this cell needs to be replaced now?

Yup

Also is that duct tape…?

Badly done shrink wrap?

Lower capacity doesn’t always equal less running time. It depends on how hard you’re using the cells. How much current per cell are you drawing continuously? In bursts?

[JoeyZ5]

Look what’s covering the nickel on the back row of cells

[Battery_Mooch]

OMG…silver duct tape. I completely missed seeing that.

[ducktaperules]

@Halbj613

just confirming this should be fine for 8p p42a
dont wanna order the wrong thing

This would be huge overkill for your application and also you wont really be able to solder it with your small iron.

[Halbj613]

Yeah was told
Apperenttly copper is way harder than silicone wire so just gonna do that instead
2x 12awg wires for series

[SJReason]

Thanks man I’ll have to dig out that cells and rewrap lol

[Halbj613]

look what just came
