The power range described is applicable to the following products: Low-power inverter, massager battery pack, LED lamp backup power supply, electronic products, solar street lamp battery pack, monitoring backup power supply, and other products. Note: For products with a current above 3A, the battery discharge rate must be above 3C. The magnification calculation formula: For a battery with a 1C magnification, the 2000 capacity is equal to 2AH*1=2A upper limit working current. 3C rate battery, 2000 capacity is equal to 2AH*3=6A upper limit working current. In use, the battery will heat up, which means that the battery rate is not applicable. In this case, it must not be used for a long time, and the battery will be damaged quickly. Note 1: Wiring 0V (B-), 3.7V (B1), 7.4V (B2), 11.1V (B3), 14.8V (B+) strictly according to the diagram, don't intentionally short circuit! Note 2: After the line is connected, it needs to be charged before output. Note 3: When connecting 4 sets of batteries in series, please ensure that the voltage of each set of batteries is the same. If they are not the same, please charge each set of batteries with a single DU and use them in series. . . During the discharge test, the battery with the fast voltage drop is a bad battery. For some customers with poor electronic foundation, please explain: Do not mix good batteries and bad batteries together! The closer the capacity\/internal resistance of the 4 sets of batteries, the better! (2 good batteries + 2 bad batteries = 4 poor battery usage effects). The attributes of the lithium battery protection board: Model: HX-4S-D20 Overcharge voltage range: 4.25-4.35v ±0.05v Siz.Find many great new \u0026amp; used options and get the best deals for 14.8V 16.8V 20A 4S Lithium Battery Protection Bms Pcm Board at the best online prices at Order2india Shopping!
