• Nominal voltage: 3.6V or 3.7V for lithium batteries (including 18650, 26650, and lithium polymer).
• Continuous discharge current (upper limit): 40A. (If the ambient temperature is high, it is recommended to reduce the load current to avoid overheating).
• Continuous charging current (upper limit): 20A.
• Suitable for: Electric screwdrivers with a starting current below 80A and power up to 135W.

The BMS (Battery Management System) protection board is designed to protect the battery from overcharging, excessive discharging, and overheating, while allowing safe charging and discharging of the battery. At the same time, it is ideal for devices that require strong performance, such as tools with motors that require high starting current.

This protection board is particularly useful in applications that require lithium batteries with high performance and safety, such as in hand tools, electric bicycles, and other portable devices.
