Hello everyone, I’m having a serious issue with my Stevens e-Inception ED 8.7 GTF (Shimano EP8 motor, Darfon E4C0G battery).
While riding uphill, the bike suddenly cut power to the motor and displayed an error code (something like E020). After that, every time I turn the bike on, it automatically shuts down again within about 20 seconds.
Before this problem became constant, the battery would occasionally trip the BMS right after charging. I had to open the battery manually and reconnect one of the BMS connectors. After doing that, the bike would work for a short time, but the issue always returned.
Now the situation is worse:
the battery won’t charge at all,
the bike still powers off after 20 seconds,
and the motor won’t stay on long enough for diagnostics.
Has anyone experienced similar issues with the Darfon E4C0G battery or the Shimano EP8 system? Any suggestions on what might be causing this or how to properly fix it?
