Giới thiệu Bảng Mạch Bảo Vệ Pin Lithium 4s 12a 14.8v 16.8v 18650 tại Lotte Market

Note:
The protective plate can not be used for lithium iron phosphate battery, hernia lamp, hand drill battery pack, electric fish battery, electric bicycle battery pack, buggy battery, 775 (4A) above motor, 1W fish eye LED lamp, Please pay attention to the combined purchase of customers!

The product is suitable for the following products:
Power Inverter, Massager Battery Pack, LED Lamp Standby Power Supply, Electronics, Solar Street Light Battery Pack, Monitoring Standby Power Supply, and more.

Note:
3A current discharge products, battery discharge rate to 3C above.
Rate calculation formula: 1C rate of battery, 2000 capacity is equal to 2AH * 1 = 2A maximum operating current.

3C rate of battery, 2000 capacity is equal to 2AH * 3 = 6A maximum operating current.
In use, the battery will heat is not applicable to battery magnification, this situation can not be long-term use, the battery will soon be damaged.

Note:
1: Strictly according to the diagram wiring 0V (B -), 3.7V (B1), 7.4V (B2), 11.1V (B3), 14.8V (B +), do not short!
2: Need to charge after connecting the line, will have output.
3: 4 batteries in series, please ensure that each battery voltage is the same, if not the same, please fill each battery separately and then use in series. During the discharge test, the battery whose voltage dropped quickly was a bad battery.

Tip: Do not mix good batteries with bad batteries! The capacity / internal resistance of the 4 batteries is as close as possible! (2 good batteries + 2 bad batteries = 4 bad batteries).
