SPECIFICATIONS

Attention:

Lithium battery protection board can not be used for lithium iron phosphate battery, hernia lamp, hand drill battery pack, can not be used for electric fish electric pool, electric bicycle battery pack, children's car battery, more than 550 power type motor, 1W fisheye LED lamp, for the above combination purchase customers please pay attention! .

The described power range is suitable for the following products:

Massager battery pack, LED lamp backup power supply, 12V electronics, solar street lamp battery pack, monitoring backup power supply, and other products.

Note: For discharge products above 3A current, the battery discharge ratio should be above 3C.

Power calculation formula: 1C power battery, 2000 capacity is equal to 2AH*1=2A operating current.

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

In the use of the battery will heat is the battery ratio is not applicable, this situation can not be used for a long time, the battery will soon be damaged.

Note: In order to achieve better consistency and balance of the equalization effect, try to use a switching source with a voltage of 17V and a current of 0.2 times the capacity to charge (the self-outage current is less than 30mA). Because the balance current of the equalization IC is about 65mA, and most 16.8V lithium chargers on the market, the charging current detection is less than 100mA, and there is no charge in the balance, resulting in an imbalance in each group of battery voltage. On the battery voltage and the output voltage there is a voltage drop problem, the working principle of this type of protection board is negative protection, just combined some will have 0.1-0.3V voltage drop, cycle charge and discharge several times will reduce the voltage drop voltage, which is a normal phenomenon. Charger try not to use 16V power supply, 4 series of lithium battery full charge is 16.8V, 16V power supply will appear insufficient phenomenon, the protection board will not protect, it has been charged, long-term use has an impact on battery life, thank you for understanding.

Note: In order to achieve better consistency and balance of the equalization effect, try to use a switching source with a voltage of 15V and a current of 0.2 times the capacity to charge (the self-outage current is less than 30mA). Because the balance current of the equalization IC is about 65mA, and most 14.8V iron lithium chargers on the market, the charging current detection is less than 100mA, and there is no charge in the balance, resulting in the voltage imbalance of each group of batteries. On the battery voltage and the output voltage there is a voltage drop problem, the working principle of this type of protection board is negative protection, just combined some will have 0.1-0.3V voltage drop, cycle charge and discharge several times will reduce the voltage drop voltage, which is a normal phenomenon. Charger try not to use 14V power supply, 4 series of lithium iron phosphate battery full charge is 14.4-14.8V, 14V power supply will appear insufficient phenomenon, the protection board will not protect, has been charged, long-term use has an impact on battery life, thank you for understanding.

The green board is a 3.7V lithium battery protection board, and the blue board is a 3.2V lithium iron phosphate protection board, and the wiring mode is the same.

Note: The installation of electronic modules requires basic knowledge and requires a certain electronic professional foundation and hands-on ability. Please purchase carefully!

Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you!

Please allow 1-2cm measuring deviation due to manual measurement.
