I had a S3 battery which was deep discharged. I changed the cells and soldered the new ones to the BMS. Now, the cartridge is giving out Err20, 6 and 17. I already did multiple resets on the BMS via RST and GND and also Cartridge Resets. What could I try next?
I have a VanMoof s3 (Bike) with a dead battery and a lab charger. Before I try to charge it up manually, is there a way to test the individual cells? How would I do that, I am more at the beginning of my "electronic journal" but I want to try and understand it. Thanks
My s3 battery is deep discharged after it being stored for a few months. Now I want to charge it up via the discharge ports with a lab charger device. I would do it outside and watch it the whole time, but I heard some people saying it's really dangerous. I don't really have to lose anything more than a dead battery. But just to be sure, I read about checking the individual cells. How exactly would I do that? Thanks
