• Discharge Protection - Prevent battery power from dying and affect the life of lithium batteries.
• Over Current Protection - Prevent the battery from being damaged by excessive instantaneous current.
• Short Circuit Protection - Automatic protection during abnormal short circuit to prevent battery.
• Temperature Protection - The NTC temperature control probe is added to prevent the damage caused by the spontaneous combustion of the battery when the temperature is too high.
• Drop Protection - When the cable is taken off, the BMS will provide no output.
