3 Series 40A 18650 Lithium Battery Protection Board 11.1V 12.6V with Balance for Drill Motor Lipo Cell Module

Description

The 3 Series 40A 18650 Lithium Battery Protection Board 11.1V, 12.6V with Balance for Drill Motor Lipo Cell Module has an integrated 10 low load resistance MOS tube and a recovery function-AUTO Recovery.

For electric drill/sprayer/LED lights/low power inverter, it delivers a continuous discharge of 40A, 100mA balanced current. (If the cooling environment is poor, reduce the current load utilization)

The nominal voltage of 3.6V, 3.7V lithium battery (including 18650, 26650, a polymer lithium battery) with charging voltage ranging from 16.8V to 18.1V. With a continuous charging current of (maximum limit): 20A, the board runs smoothly. The balanced version is suited for beginning currents of less than 80A and power of less than 135W. (with balance).

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.
