That must explain why there are so many used and rebuilt Porsche lithium batteries and rebuild services listed on Ebay. That issue must be unique to the Porsche BMS if it locks you out if it drops below a certain level. The BMS systems in aftermarket lithium batteries don't do that. If anything, if it drops below a certain level, it will disconnect to protect the cells, but will reconnect upon recharge (most), or by pressing a reset button. You want that cell protection because if just one cell gets completely discharge, it cannot be recovered.
I only discharged this battery down to 8 volts in a test but the description states:
【Automatic BMS and Maintenance-free】 : The built-in Battery Management System (BMS) protects your battery from Over Charge and Discharge, Over Current, and Short Circuiting. The BMS disconnects the battery when abnormal conditions are detected, and it can be reactivated without the need for a higher voltage input. Lithium motorcycle battery will not overheat or catch on fire, even if punctured, making it a safe choice.
This battery comes with a two year warranty, and I'd think if it bricked itself on just one accidental discharge, they would have to deal with a lot of returns.
