BMS 4S 40A 16.8Volt 18650 Lithium Battery Charging Protection Board Module

Product Description

• Product Name: 4S 16.8V 40A lithium battery protection board
• Charging voltage: DC 16.8V~17V
• Continuous discharge current: 40A maximum
• Continuous charging current: up to 20A
• Balance Version Product size: 45*60*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 170WNote:

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!!).
2. strictly according to map wiring 0V, 4.2V, 8.4V, 12.6V, 16.8V, do not deliberately short circuit.
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.
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.
5. High Quality; Compact size and lightweight; High-accuracy voltage detection circuit; fine workmanship and durable; stable performance.
6. Multiple Protections: Over-discharge protection, overcurrent protection, overcharge protection; High charge and discharge current
7. LOW STANDBY CURRENT: MOS transistor can control the battery charge and discharge, low standby current consumption.
8. 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 .
