14.8V 4S lithium Battery BMS Module With Protection
14.8V 4S lithium Battery Protection Board This shop sells the products contain electronic technology, if you do not understand or cannot determine whether the application of your product, please not buy in order to avoid unnecessary trouble. Thank you (beginners not to buy)
Be Careful：
The protection board can not be used for lithium iron phosphate battery, lamp, electric drill batteries, electric fish machine batteries, electric bicycle batteries, children car battery, 775 (4A) above 1W fisheye motor, LED lamp, for the combination of customer purchase please note!.
The described power range is applicable to the following products:
Low power inverter, massager battery pack, LED lamp standby power supply, electronic product, solar street lamp battery pack, monitoring standby power supply, and other products.
Note: 3A discharge current above the product, the battery discharge rate of more than 3C.
- Rate calculation formula: 1C ratio of the battery, the capacity is equal to 2000 2AH*1=2A maximum operating current.
- 3C cell, 2000 capacity equal to 2AH*3=6A maximum operating current.
- In the use of the battery will be heating is the battery rate does not apply, this situation can not be used for a long time, the battery will soon be damaged.
Note 1: In strict accordance with the wiring diagram 0V (B-), 3.7V (B1), 7.4V (B2), 11.1V (B3), 14.8V (B+), do not deliberately short circuit!
Note 2: Connect the line after the first charge, there will be output.
Note 3: When the battery is connected in series, please ensure that the voltage of each battery is the same, if not the same, please be full of each battery and then use 4 series. In the discharge test, the battery with a fast voltage drop is a differential cell.
Note 4: Do not mix the good battery and the difference between the 4 groups of battery capacity / internal resistance closer to the better (2 good battery +2 difference in the use of the effect of the difference between the effect of the battery =4).
