@lemur Almost done, I need to get the raw metal parts painted or powder coated.
Rides like a dream too, totally predictable behavior. I'm using a Ubox 100v 100a with 22s but I only weigh 155 lbs and set full charge at 95%.

@lemur Update.
Pint suspension build with Ubox 100v.
Only one in the world, almost complete, just waiting for my Molicel cells so I can build the 20-22s battery and make a simple main battery harness.
The supension metal pieces are still in the raw, will be either painted or PC.
-Ubox 100v 100a controller

• Techrails Stiletto rails
• Px battery box
• custom printed mini fenders from Floatershack
  This build is based on my proven XR suspension models, except the components are lighter gauge as the XR suspension was overbuilt.
  The stock controller box was shortened to make room for the swingarm.

Since the XR suspension builds have proven bulletproof for up to 27s for the last couple of years, it's time to build one to fit the Pint.
It's just a start of the build but I'm confident that this will work, this design is based on the XR design, but scaled down with smaller com ponents.
I have Lia's PX battery box that has been used in another build.
Ubox 100v 100a and will be 20s.

@kusosan I switched to the Mk8 because I'm running 27s now and 27s because Onewheel GTS chargers are perfect for this application.

@syanelli Charging does not do anything to the controller as the charge negative goes to the bms.

@syanelli Here's a simple crude diagram, but basically I eliminated the positive charge wire as it is tied into the controller positive from the charge port.

I replaced the Maxkgo charge only bms with the Stokedstock bms, I don't believe the Maxkgo ever balanced my battery pack as I never charge to 100%, the SSbms can be set to balance at a lower cell voltage.
After a few charge cycles with the SSbms, I can see the cells even out and is now at 0.01v deviation and in this case I set SOC to 100% at 4.15v.
The SSbms has it's own app and will read cell voltages in real time with many programable settings.
The SSbms is the best bang for the buck in my opinion.

@thedoc2025 Do you get any error messages on the "Float control" app?
Also before you change any settings, back up your configurations.

@kusosan I never used the Thor 300 rgb light control, as there seems to be a lot of confusion and wiring issues.
Instead I used buck converters from the aux, ardruino nano for rear lights and white led strips for front lights. That system has been working well so I didn't feel the need to change it. There's a picture of my Thor300/XR set up earier in this post.
I'm no longer running a Thor and have moved over to Ennoid MK8 vesc now.

@lia Thank you!

My main board is now 27s1p (113volts) using Molicel 45b's. It's not top speed I was after, but the quick acceleration that I like and the rock study nature of the ride.
Specs:
-27s1p Molicel 45b's
-Ennoid MK8 controller
-Stokedstock semi dumb BMS which has it's own app to show cell voltages
I choose 113v because GTS chargers are easily available and especially ones that have the charge connector cut off for 30-32 volt vesc conversion. My charger was gifted to me because the charge end was cut off.
Since the MK8 has no useable aux power out for lights, I went with a flashlight with a cheap tailight mounted with a bicycle snap on flashlight holder, I ride goofy so this setup works for me.

@kusosan I used no paste or pad at first, then I tried thermal paste, but there was no difference in max temp. although I live in the the cool Pacific northwest.

@kusosan I made mine, just a simple 1/8 sheet . You can mount directly to the thin aluminum lid , but I decided to use a plate to stiffen the lid and also so I can use counter sink screws to mount the Thor.

@charve You can use the Pint battery to test your Xr. I'm not familiar with th e torquebox setup, but you can put up to 27s1p 21700 cells in a stock (with slight mods) , I'm running 24s1p because I have an 100v charger from a dead EUC.

@lia You are a perfectionist! I can't believe the attention to the smallest detail!
Totally insane!

Third model suspension build almost done.
-Ennoid mk8 vesc
-Stokedstock bms
-Stokedstock V3 footpad sensor
-24s1p Molicel 45b cells
-Ohlins TTX air shock 190 x 45mm
-Pint wheel
-Burris 11x5.5x6 Tx22 tire
-Rails are 5/8 inch longer and professioally painted
-Fm wood footpads

• 1/8 inch aluminum plates under the footpads
  -Custon wiring harness, no lights yet
  I have to source mini fenders to fit.

@blankman Dowgrading with stlink requires that you have extracted your bootloader and settings for the correct serial number, mileage.
If you use someone else's bootloader and settings then you need a special program to change the serial number, mileage.
After stlink, then you can Rewheel with encrpted file 5040, if you don't have the 5040 file then no point going any further.
What was your goal try to get into factory mode?

I just received the Ennoid MK8 with the BT module.
I rewired a stock XR/Plus power switch as the MK8 needs a momentary NC switch, the stock XR switch is wired NO, but has a NC terminal on the switch, the led lights up fine on 5v, normal XR/Plus led is fed by 12v.
This switch makes using the stock XR controller box a lot easier.
The 6.05 firmware is already loaded in out of the box.
I will be running 24s1p Molicel 45b for now and a Stokedstock bms

@loaffette They're bright but doesn't thow a beam very far, I still use a helmet mounted bicycle headlight when I ride at night.

@loaffette I use to carry a solar charger, a 36v hoverboard battery, charging adapters, in a camera bag for group rides.
The solar charger converts the 36v to any higher voltage up to 90 v all programable with memory for different boards.
I've gone to 24s, so I can't use this anymore.
