Over Voltage / Charge: 

The Nano-HD will internally disconnect if the voltage ever gets above 15.3. This is way above all motorcycle and Power sports normal voltage range so if this voltage is reached, more then likely there is a charge system problem and the battery will be safe no matter what the issue is. 


Over Discharge / Low Voltage: 

The Nano-HD will internally disconnect if the voltage ever falls below 10v. This is way below all motorcycle and Power sports normal voltage range so if this voltage is reach it would indicate a problem like a parasitic draw.  The battery Will disconnect itself to keep from being completely drained to Zero volts. The BMS will remain in the off or unhooked position until voltage from a different source is applied to the battery. At that point the BMS will turn back on to allow the bike or power sports vehicle to be started.
