3 series 12V18650 lithium battery protection board 11.1V 12.6V defense over charge and protective work current 8A

Product size: 30*30*3mm

Upper limit working current: 8A Upper limit Moment current: 12A

Excessive voltage voltage fan: 4.25 ± 0.05V over place voltage fan 2. 5V ± 0.05V

Charging voltage: 12.6V-13V Static current: Small T30UA

Short -circuit protection: protected, delayed self -recovery

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 OV (B-), 3.7V (BL), 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 three sets of batteries in series, please ensure that the voltage of each group of batteries is the same.

During the discharge test, the battery that drops quickly is a different battery.

Explain: Do not use good batteries and different batteries together!The capacity/internal resistance of 3 groups, the closer to the better!

(2 good batteries+1 different battery use effect = 3 different batteries)
