3S 25A:

3 Series 18650 battery

11.1V (Li-ion 18650 or li-ion battery rated voltage)

12.6V (Li-ion battery full charge voltage)

10.8V ( Lipo battery pack rated voltage)

The lithium battery protection board is not included the welding tabs.

BMS activate method : Use 12.6V Li-ion charger to charge it.

Introduction:

NOTE:

1) This board is not suit high power electronic tools, if use for screwdrier and drill,electric bike series make,fishing machine and 1W LED, please don't buy this.

2)Above 3A device,means the battry discharge rate is more than 3C.

1C rated battery, 2000mah equals 2ah*1=2A max working current.

3C rated battery means 2ahx3=6A Max working current.

Balancer is just a Auxiliary function, The balancing means when the battery charging,each series battery need with the same voltage.when ONE cell voltage get 4.2V ,the other cells not, the first cell voltage will discharge to wait the other cells rising to the same level.

Note:

battery internal resistance differences within 5 milliohm, voltage within 0.03 V voltage, capacity vary within 50 ma

Feature:

1) high-accuracy voltage detection circuit;

2) terminal of the charger using high voltage device;

3) Built-in three-stage over-current detection circuit (over-current 1, over-current 2, or load short circuit);

4) MOS transistor can control the battery charge and discharge;

5) low standby current consumption.

Scope: Nominal voltage of 3.6V, 3.7V lithium battery (including 18650,26650, polymer lithium battery)

Product Size: 42 * 60 * 3.4mm (balanced version)

Product weight: 9.8g (balanced version)

Charging voltage: 12.6V - 13.6V

Continuous discharge current (upper limit): 40A (if the cooling environment is not good, please reduce the load current use)

Continuous charge current (upper limit): 20A

Balance version: suitable for starting current below 80A, power 135W below the drill. Now this 4S 40A balance version has upgrade to new !1, increased anti-interference function,2, reduce the large current heat by 30%,3, starting power increased from 135W to 220W (4S40A)

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, 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: 3 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.

For some of the poor basis of electronic customers to explain: balanced charge is only auxiliary functions, try not to put a good battery and poor battery mixed together! 3 sets of battery capacity / resistance closer to the better! (2 good battery +1 Poor battery use effect = 3 poor battery use effect). Package include:1* 3S 40A Protection Board
