Samsung 50S are one of the best cells out there, but far higher amps than we need or will use. Did you think about using Samsung 50E instead for cost purposes?
Yes
Yes I thought that waking the charger would be enough for it to provide a voltage, chargers are usually dumb, but this charger is smart.
Even using the charger ilwith another battery while it is charging the bike, I get an error 449B BAT HW. That error doesn't exist in the manual.
I'm really interested to see how you are getting on. I'm working on a another project with a similar aim, but I'm keeping quiet at the moment as TQ will likely release firmware's to try and block these kinds of modifications. Their charger is so proprietary, so far haven't been able to get it to...
"The original BMS is easily removable from the original battery to avoid compatibility problems."
If you are manufacturing a bigger battery, I presume you will reuse the existing BMS?
Judging the proprietary plugs on the Exe and the charger wakeup nature, TQ may have implemented some sort of RAM on the BMS which if unpowered will essentially brick the board unless you can power it from another source while you swap out the cells. Bosch do this and other electric devices like...
Are there any intentions for the consumer to be able to update their own firmware, inline with most other products?
In the mean time, will the dealer have a list of changes the firmware includes, for transparency of what is being changed in our bike?
Could be your physical button on the screen? I believe the bike and/or screen turns off after 15-30 mins, at least my mate who couldn't work out how to turn it off said so as he just left it on.
The screen itself doesn't seem that durable, the layers underneath get pressed together and effect...
Same with my 9.5 I bought at the weekend, doesn't activate 'Extended centre button functionality', whatever that will be.
I'm always careful with firmware updates, they can often lock good capabilities out (anti right to repair). Hopefully they release some patch notes
