HX-2S-S02A 2S 7.4V 8.4V 2A 18650 Lithium Battery Protection Board Overcharge and Overdischarge Prote

Product parameters:
Model:HX-2S-S02A
Charging Voltage: 8.4V-9V Overcharge Voltage Range: 4.25V &pm; 0.05V Overpressure Voltage Range: 2.5V &pm; 0.05V Upper Limit Operating Current: 2A Upper Limit Instantaneous Current: 2.5A Quiescent Current: <10uA Size: 27 * 6.6 *2.5mm Short Circuit Protection: protection, delay self-recovery
Applicable Scope:
The power range is suitable for the following products: massager battery pack, LED light standby power supply, 12V electronic products, solar street light battery pack, monitor backup power supply, and other products.
Note:
The protection board can not be used for lithium iron phosphate battery, hernia lamp, hand drill battery pack, electric fish machine battery pack, electric bicycle battery pack, children`s car battery, motor, 1W fish eye LED light!
Note 1: Wiring 0V (B-), 3.7V (B1), 7.4V (B2), 11.1V (B3) ,14.8V(B4),18.5V(B5),22.2V(B6),25.9V(B+) strictly according to the diagram, do not short-circuit intentionally! Note 2: After the line is connected, it needs to be charged before output. Note 3: When connecting 7 groups of batteries in series, please ensure that the voltage of each group of batteries is the same. If they are not the same, please charge each group of batteries separately and use them in series. During the discharge test, the battery with the fastest voltage drop is the poor battery. Note 4: Do not mix good batteries and bad batteries together! The closer the capacity/internal resistance of the 7 sets of batteries, the better! (4 good batteries + 3 poor battery use effect = 7 poor batteries use effect) .
Package included:
