I’ll buy them for spares if you’ve given up with themNo I didn't fried the controller as I didn't overvolt them.
The fault were the following amongst the 3 bbs02:
- intermittent acceleration when raining
- all 3 had a broken LCD display for various reasons (bike felt on the floor, a small drop on the display, etc)
- one had a small click sound when pedalling
- currently the last one has an error 30 on the cracked LCD. I don't have time to diagnose.
