@ascentale @bikenite The old Bosch PowerPack 400 died two times. The first we throw down to concrete and it stopped working. I was afraid to send it to get it repaired. Instead I bought a new one. Years later the new died during the loading after very heavy rain at 1 degree Celsius. I send to a repair service. The BMS got wet, died. It was changed. Battery worked until I sold the bike last year. So yes, I had issues, but always my fault and never related to fire.
