Function:
1. Protection from Short Circuit: Automatic protection to the motherboard and battery when short circuit occurs. Input Overvoltage Protection: OVP circuit prevents voltage surges from damaging the device.
2.Protection from Output Overcurrent: Monitors output current and shuts off when current exceeds the maximum limit to protect the device.
3.Output Overvoltage Protection: Monitors output voltage and shuts off when voltage exceeds the maximum limit to protect the device.
4.Protection from Overcharge and Over-discharge technology is adopted to prevent overcharging and over-discharging thus preventing any damage of the Li-poly batteries.
5. PTC Protective Circuits for the Cell: Imported battery cells are equipped with PTC to effectively control current and provide protection when temperature and current exceed the maximum limit. current exceed the maximum limit.
