BMS 3S 40A 11.1v 12.6V Li-ion 18650  board .

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.

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.
