Product Description
HM-4S-01 6A 4S Li-ion Battery 3.7V 18650 Lithium Battery Charger Protection Board 4 Pack
The protection board can not be used for iron ion polymer batteries, lamps, electric fish machine batteries, electric bicycle batteries, for the combination of customer purchase please note!.
The described power range is applicable to the following products:
A small power inverter, battery, LED light massager standby power supply, electronic products, solar battery, standby power supply, monitoring 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 must 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.
For some poor customer electronic note: do not good and poor battery mix! 4 battery capacity / internal resistance of the closer the better! (2 battery +2 battery =4 a poor effect of poor battery effect).
The properties of the lithium battery protection board:
Model: HX-4S-A01 over voltage range: 4.25-4.35v + 0.05v
Size: 72*17*3.0mm over discharge voltage range: 2.3-3.0v + 0.05v
