3 series 12V18650 lithium battery protection board 11.1V 12.6V band balance 25A overflow over charge and protection

Notice:

This protective board cannot be used for lithium iron phosphate batteries, hernia lamps, flashlight drilling battery packs, and cannot be used for electric fish battery packs, electric bicycle battery packs, children's vehicle batteries, 775 (4A) motors, 1W fish eye LED lights, 1W fish eye LED light,Please pay attention to the customers who are purchased by the above group!Essence

The described power range is applicable to the following products:

Massage battery pack, LED light spare power supply, 12V electronics, solar street light battery packs, monitoring spare power supply, and other products.

Note: Discharge products above 3A current, battery discharge multiplier is 3C or more.

Multiple calculation formula: 1C multiplier battery, 2000 capacity is equal to 2AH*1 = 2A working current.

3C multiplier battery, 2000 capacity is equal to 2AH*3 = 6A working current.

The battery will be fever during the use of the battery, which is not applicable to the battery rate. This situation cannot be used for a long time, and the battery will be damaged quickly.

Note 1: Strictly follow the figure 0V (B-), 3.7V (B1), 7.4V (B2), 11.1V (B+), don't deliberately short circuit!

Note 2: After connecting the line, you need to charge it before there will be output.

Note 3: When connecting 3 sets of batteries in series, please ensure that the voltage of each group is the same. If it is not the same, please fill in each set of batteries alone and then use it in series.During the discharge test, the battery that drops the fastest voltage is a poor battery.

Explain: Do not use good batteries and different batteries together! The capacity/internal resistance of the 3 sets of batteries, the better! (The effect of 2 good batteries+1 different batteries = the effect of the use of 3 different batteries).

Attributes of the lithium battery protection board:
