3S 40A Lithium Ion BMS – For 11.1V Battery

The 3S 40A Lithium Ion BMS is a high current Battery Management System for Lithium Ion Battery Pack. The BMS provides Overcharge, Over Discharge, and Short Circuit Protection. This BMS is for a 3 Series Battery Pack i.e. 11.1V Lithium Ion Battery Pack.

The full charge voltage of the Battery Pack will be 12.6V. The charging voltage should be 12.6V to 13.6 CC/CV. This BMS is not a balanced charger for the Battery Pack. The maximum discharge current of the BMS is 80A. However continuous discharging current is 40A.

This 3S 40A Lithium Ion BMS should not be used with Drill Motor, as this does not provide Balance charging of the Battery Pack, and might damage the battery as well the BMS.

Note: Do not connect Lithium Ion Battery cells with different voltage or resistance to the module, as this can damage the battery cells as well as the BMS.
