If your BMS is unresponsive due to a failed firmware upgrade or appears to be “bricked,” we’re here to help. Simply provide the serial number of your battery, and we’ll email you detailed recovery instructions along with the correct software to restore functionality—quickly and conveniently.

Important Note:
Due to a chip shortage during the COVID period, some battery models were produced with different BMS chipsets. As a result, multiple firmware versions exist. To ensure compatibility and avoid further issues, we require your battery’s serial number to verify the correct BMS revision. We’ll then send you the most up-to-date, confirmed firmware specific to your model.

Support Guarantee:
If you encounter any difficulties, our support team is available via email to assist you through the recovery process.
