This only works when the assist mode source is set to remote/MODBUS, this is how I control assist levels with my display. Also be aware of the Features3 bitwise switch, 'throttle bypass assist level'.

I am trying to re-upload to Mega right now. For some reason it's going at 150 bytes/s! :shock: If it remains uncooperative I'll work something else out and PM you-- host it myself, or maybe telegram if you have that. PM me or post in this thread again on the off chance I forget.

The software part would be relatively straightforward (The display backlight slider is an example of a screen button bound to one of the Rpi GPIO outputs) For the hardware you can definitely look up guides. Changing the GUI to add a new button vs. reassigning one is slightly more involved. You...

Just want to chime in and say, I've been watching this project closely for years. I'm interested. And from what I can tell you've made outstanding design choices at every turn. Props! :bigthumb:

Real late here but I can confirm you are correct. The modbus commands used for the physical serial connection e.g. In my open source display, also work when connected to the controller via Bluetooth. They actually use the same serial port on the board (e.g. Since I poll the physical port...

I have a BAC8000 and a QS205. Personally I would not use less than a 4000, it really is pretty well matched for the QS205. The biggest reason I like having an 8000 over the 4000 is the phase amps-- I've got upgraded phasewires, statorade, and hubsinks on my QS205 and while 450 is a very...

Take another look at this mount that goes inside the Qulbix frame. It may not be immediately obvious but it does actually have complex curves. E.g. look at the extended mounts for the relays up top-- one side is further from the profile. In principle this is just like modeling half of a wing...

I did this for a couple of the parts I printed on my bike. I took ~80 pictures and loaded them into Agisoft Photoscan, and let it work its magic for about 16 hours to create a mesh which can be used as a guide or if its good enough quality, to subtract/boss from your model. That said if it was...

I'm late here, but have 3d printed; 1. Agnius NESE snapfit 18650 modules for a 3.25kWhr pack (22mOhm lead-to-lead resistance for 21s14p 30Q cells) 2. screw clamps to secure the battery, 3. internal mount that fits inside the front of a Q140 frame box for a Pi, 12v system, relays, a 4...

So you're gonna get a new shaft when you have to replace your sprocket? :shock:

Just pushed updated gui displaying up to 24 cells. :thumb:

In that case single/dual port doesn't really matter with respect to the display. As long as it's a JBD bms it should work with this display. Mine from ICGOGOGO has separate charge/discharge switches but only one port. At least, it does in software. I haven't tested to see if they cut out both...

That depends entirely on your BMS/controller. I'm bypassing BMS for controller discharge via 3x 100 amp MNEDC-100 breakers, and do use a 300-amp battery current limit for my 350-amp rated pack. With this config the BMS detects only charging current and 12v accessory discharge. Controller detects...

If you use LFP you'll want to update the voltage:state-of-charge mapping, named 'socmap'. Since LFP have phenomenally stable voltage in the middle-80% of their SOC, like any other coulomb-counter you may have to occassionally charge or discharge them beyond that 3.3v/cell plateau to reset it and...

Finally, my last bump and necro of this thread for an age, unless anyone has suggestions/requests. Coolest feature of latest update is the ability to hack access codes on the controller. :twisted: The other planned additions to this project like the lojack and the intelligent route-based range...
