2Pack Enhanced 4S 40A 16.8V Li-ion Lithium Battery Protection Board PCB BMS Charger Protection Circuit Balance Charging Module for Drill Motor Motorcycle Battery (4S 40A)
- High Quality; Compact size and lightweight;High-accuracy voltage detection circuit; fine workmanship and durable; stable performance.; Multiple Protections: Over-discharge protection, overcurrent protection, overcharge protection; High charge and discharge current; LOW STANDBY CURRENT: MOS transistor can control the battery charge and discharge, low standby current consumption.; Applications:It is suitable for lithium batteries with nominal voltage of 3.7V and full voltage of 4.2V (including 18650, 26650, polymer lithium batteries, no size limit).Besides, it can use for electric drill with starting current below 80A and power below 135W .; If you want to start the drill successfully, it requires 3pcs15C-20C power batteries, or 6pcs10C-15C power batteries (Note: ordinary 18650 battery can not start the drill!! Recommended power battery models: VTC4, VTC4A, VTC5A, VTC6). About connecting cables, we suggest using more than 3 square millimeters copper wire.

Product description Introduction
Product Name: 4 string 14.8V 16.8V 40A lithium battery protection board
Charging voltage: DC 16.8V ~17V
Continuous discharge current: 40A maximum (if the heat dissipation environment is not good, please reduce the load current)
Continuous charging current: up to 20A Enhance
Version Product size: 44*55*4mm
Applicable choice: applicable to the nominal voltage of 3.7V, fully charged 4.2V lithium battery (including 18650, 26650, polymer lithium battery), can be drilled below 170W
Notice Note 1: The successful start of the drill requires three 15C-20C power battery, or six 10C-15C power battery (ordinary 18650 can not start the drill!! ).
Note 2: strictly according to map wiring 0V, 4.2V, 8.4V, 12.6V, 16.8V, do not deliberately short circuit.
Note 3: When the load of the brush motor is used, try to connect a non-polar capacitor (withstand voltage above 25V, capacity 10uF-100uF) to the motor's positive and negative terminals to prevent the reverse spike from the motor. Break the MOS tube. Note 4: 4 groups of batteries in series, please ensure that the voltage of each group of batteries, if not the same, please fill each battery separately and then use in series. The The Discharge test, the voltage drop faster battery that group is poor battery. Discharge diagram The RIGHT figure shows the module discharge diagram. The battery is 4 strings. The connected battery needs to meet the 40A discharge current. It can be realized by paralleling the battery or purchasing a battery with a large discharge current. For example, the battery 2000mAH, the discharge multiple 10C, then only need 4 series 2 and the maximum current can reach the discharge current 40A, stable discharge requires 4 strings 4 and can be, and need to pay attention to heat dissipation, the discharge battery power will drop rapidly. Charging diagram The LEFT picture shows the battery charging diagram, 4 series of batteries, the actual full charge, voltage 16.8V, charging voltage DC17V-18V, charging current depends on the battery connected, the maximum does not exceed 20A.
