2S 12A 7.4V




2S 20A Balanced

Scope of application: suitable for lithium batteries with a rated voltage of 3.7V and a full voltage of 4.2V (including 18650, 26650, polymer lithium batteries, and the size is not limited)

Product size: 48*20*3.4mm (balanced)


Charging voltage: 8.4V - 9.0V

Continuous discharge current (upper limit): 20A (if the cooling environment is not good, reduce the use of load current)

Continuous charging current (upper limit): 10A

Balanced type: suitable for electric drills below 25A and below 50W, or starting current for resistive loads below 168W, with balanced charging function.

Note 1: The successful start of the electric drill requires two 10C-20C power batteries, or four 5C-10C power batteries (ordinary 18650 cannot start the drill!)! 0V and 8.4V cables, use more than 2mm2 copper wire (no nickel plates!)

Note 2: Connect 0V, 4.2V, 8.4V strictly according to the diagram. When connecting the battery for the first time, it needs to be charged before output.


Note 3: When the battery is charged, the ''430'' resistance heating is a normal phenomenon, indicating that the equalization circuit is working properly; if the ''430'' resistance is also heating when the battery is not charged, please check whether the wrong line is connected.

For customers with poor electronics fundamentals, a note: don't mix good and bad batteries! The capacity/internal resistance of the 2 cells should be as close as possible! (1 good battery + 1 bad battery = 2 battery usage effects).

The power ranges described apply to the following products:
Battery packs for massagers, backup power for LED lights, 12V electronics, battery packs for solar street lights, backup power for monitoring, and other products.
Note: For products with a current above 3A, the battery discharge rate should be above 3C.
Rate calculation formula: 1C rate battery, 2000 capacity is equal to 2AH*1=2A upper limit working current.
3C rate battery, 2000 capacity is equal to 2AH*3=6A upper limit working current.
In use, the battery will heat up, but the battery rate is not applicable. In this case, it must not be used for a long time, and the battery will be damaged quickly.
Note 1: Strictly connect 0V (B-), 3.7V (B1), 7.4V (B2), 11.1V (B+) according to the diagram, do not intentionally short-circuit!
Note 2: After the cable is connected, it needs to be charged before there is output.
Note 3: When 3 groups of batteries are connected in series, please ensure that the voltage of each group of batteries is the same. If they are not the same, please fully charge each group of batteries and use them in series. During the discharge test, the voltage drops. The fast battery is the poor battery.

For some customers with poor electronic foundation, please do not mix good batteries with bad batteries! = Use effect of 3 poor batteries).
