Engage Professional Repair or Battery Replacement

Since the battery is outputting 1V due to internal hardware failure, it is likely beyond the scope of user-level resets or charging attempts. Follow these steps to address the hardware failure:

1. Contact the e-bike manufacturer or an authorized service center to report the 1V output reading and verify your warranty status.
2. If the battery is out of warranty, consult a certified e-bike battery technician to determine if the internal cells can be safely rebalanced or if the BMS circuit board requires professional replacement.
3. If the battery is deemed permanently degraded or 'bricked,' purchase a certified, manufacturer-approved replacement battery to ensure system compatibility and safety.
4. Dispose of the faulty battery at a designated lithium-ion recycling facility; do not attempt to open the casing or dispose of it in household waste.
