Just to share here, as far as it's not known already:

Chi re-did the CBSO battery for use with VESC. It includes a bms and comes as 20s2p 18650 config. Think using the Samsung 30q. It needs a switch on the vesc (like raiden/lfoc3 etc).
The battery fits in the stock casing.

Igor (Onewheelriders workshop) also did a collab with badgerwheel and is about to release a VESC battery:
A 19s2p 21700 pack designed for use with the Ennoid Xlite bms (because of how the balance connectors are configured). It comes with a injection molded casing with very good water resistance.

@ed_co Agreed! Every fart the aftermarkets create costs gold nowadays. Greed is key, getting ridiculous. I sometimes feel like selling my shit when XR's die and get a Ninebot z10. It's not as fun but i notice my pride is starting to get in the way.

I do understand making the rotor from a chunk af alu is expensive so the pricing is somewhat understandable. People will buy it, it's design+need. But fuck no i will NEVER buy this.

@notsure Sorry;)

So my ride:
34km paved and pretty hard trails. Avg 35kph cruise on pave.
Speeds: Pushback set @80% (of available capacity). The lower the battery gets, the earlier pushback comes. At the top-end of the pack i hit 45kph, before pushback. I eased down and continued most of paved part between 35 and 40kph. Started hitting pushback after using over 65% of the battery. At nearly empty pack still confidently hitting 34kph, sometimes pushback kicked in on accellerating carves. Could have upped the limit to 85% but i did not feel like getting off the board.

Torque. Crazy. Never felt like even close to nosedive. Imagine going up a dirt hill with XR where it will slow down, bury the nose and shutdown?
On this thing i can ride up, stop in the middle, push down the nose and continue.
Nudging a curb at low speeds is like going up a "bonk" bump. Just climbs up.

Ride feel The butteryness of Mission with Delirium when i need it. It's so damn smooth. I can imagine beginner riders will find it tricky cause it feels even less artificial than Mission. Just so smooth.

I just need my damn varials cause im not used to riding straight rails anymore.

So 420wh battery lasted me 34km into capt morgan. Might get over 40 if not pushed that hard.

People think im the village idiot. But i dont care what people think as most of em are envious fools that forgot they're alive. Even doubt if all have a soul to start with.

I would like to add to this. There are several cases where error 16 showed up that have nothing to do with chip or wiring. I ve suffered from a pretty rare case myself on a 4209/4132 board where a CBXR  was installed. Clearly no-one including Chi believed that it wasn't my install error and advised i replace the harness. Off course i tested the harness to ensure it had no flaws. Im quite neurotic and made absolutely sure all components were working before and install was done as clean as it gets.

What happened:
After install the board worked fine for a couple of charges. But suddenly i was faced with a buzzing phone mid-ride, the tail sunk into the asphalt (like empty-battery pushback) and the board started a wild accelleration with tail scraping the floor. Bailout was only way to stop which happened a couple of times in full traffic...pretty scary if you dont expect it.

Conditions:
Some conditions had to be met for this to happen.

• App needs to be at 1%. So the board calculated that full stock battery capacity had to be used up.
• Voltage needed to drop below 53v. Typically the voltage after the error would be between 53.4 and 52,8v.
• Below pushback speed. Im afraid that, if this error happened above pushback speed, the board likely would nosedive without warning. I cannot be sure but lucky i did not have to find out in the field.
• A reboot of the board AFTER the error showed up guaranteed i was able to ride the board till empty.  No more error16.

After some thinking and troubleshooting to discard other things causing problems it occured to me that the board simply had no other option to display this error, thus 16 showed up. What probably was happening is a critical error where the board cannot resolve unless rebooted. There are possible cases where it occurs and even a reboot does not solve it, bricking the board (4210/4150 boards that were initially lucky to have a functioning cbxr at start).
Also the possibility that some boards do not carry the app-indicated firmware in all components: a 4132 controller with non-4132 bms.

What can be concluded is, that app indication is not always what's installed. Also the coding is said to be poorly done.  I know nothing about coding but my thoughts were supported by people working/flashing/repairing this stuff.

My problem was solved: i sent in my bms to have it flashed to a compatible custom firmware. This is possible up to/incl 4209/4132 boards.

@lia Cheers Lia,
Sorry for the username, Im just "Vommbat" on Reddit, MacIak on forums. No other media really, like oldskool forums so thanks for this!!

@lemur So far im able to ride 50km in one go (cbxr) without any issues so fatigue is no problem yet. Weirdly enough riding WTF rails in mission (bit nose-down) even increased the comfort level more. But it must be a sweet sensation having an enhanced floaty feeling. I would certainly miss the connection with board and terrain i think. Still will try a suspension board as soon as i get the chance!

@lia Pissed off lotsa people..

@biell Heat shortens the de-molding process. Im thinking it could help after de-mold as well cause they're not fully cured yet. I could be totally wrong, know jackshit of this material really🤣

The softer one bonks fine in the limited room i have in the yard. Not impressive but neither am i...just bonk stuff to get over it on trails usually.

@s-leon said in The new (unofficial) Onewheel Forum:

@lia -- Keeping this forum civil, constructive, and friendly sounds perfect to me. Call on me if need be. Great forum!

@lia same here. Intend to live here more often, regular Socialmedia fries my brain.

@biell Sure will do! Honestly no single CBXR fits in the casing properly. It's not that the foam only compresses. If you measure, even visual you will see a slight bulge both on the lid and casing. I too had not much issue installing it, just hold down by hand and cross-tighten the bolts. But this force is not to be underestimated. Now if i remove the lid i can put it back on an it just falls into place without pressure.

@s-leon
I was having the same before my last spill. Happily cruising at 22-23mph and forget how little margin there's left. I tuned down 1 mph, maybe 2😂.

The "field weakening" using back-emf of the motor increases the max rpm of the motor but the cost is torque. Definitely will not use this on vesc where rpm is true and reliable. So for more speed add more cells;)

@biell Above updated: comes with lid, CBXR will fit no problem!

It's an ok deal. Not expensive, not cheap.
You can ride it, it's fun.
The hub, tire, footpad..there you have your £500.

The lids of the boxes are good if you wanna go for a vesc build etc.

When parted out, the controller can be sold too;)

@biell Custom shaping will never be Mission. I played with so many settings but the weird surging just does not feel right. Now i just use plain Mission and ride level at pushback;)

The angle as i measure is 4deg. Have no digital gauge, just by hand.

@notsure You can't! Some custom setting is fairly similar to Mission but there is more surging. Also changing the nose-angle helps to ride level until PB but at low speeds, when crawling through some technical trail, the nose will only rise after accellerating so nose clearance remains a problem. A tiltkit is the only way to keep Mission, ride switch, clear terrain etc but it's a pretty intensive mod.

@biell You could get a tiltkit or just diy tilt the controller? Needs about 4-5mm. It creates a different set of problems though. The TFL tiltkit killed a bunch of controllers (how is it kept silent?!). I suspect cause of a capacitor getting squeezed into the bottom of the box which i found out during own experimenting. I asked/adviced Jeff. He tactically avoided answering any questions about it.

@biell When my board with WTF is level, the app shows -3.7 deg. So assuming WTF are 4.2 deg, it would mean that it would be sitting nose-down by 0.5 deg on straight rails for the app to show 0. When the board is really level, this would be -0.5 in the app.

So your board still deviates 1.27 deg extra..

The pcb is mounted under the lid with 3mm spacers. You could remove (or replace with shorter spacers) the front ones which will not mess too much with the connectors (opposite tilting also puts them at an angle which is no problem).

Edit: see img when i tilted the frontside

Only thing is the thermal pad, and if anything on the underside of pcb gets pinched against the lid.. gotta see if there's any issues there. I think this could work.
Edit: maybe not..there's lotsa stuff in the front that could be pinched against the lid without any spacer. Need to open to really see?!

@lia Had some catching up to do here. Omg im speechless!

@biell I just came back from my first ride on 20s. Think "Tuco" will be my main board, its unreal.
