Main Functions:
Overcharge protection, over discharge protection, short circuit protection, over current protection.
18650 lithium battery charging protection module 3.7V
- Note 1: Do not intentionally short circuit according to the wiring of the figure!
- Note 2: After the line is connected, it needs to be charged before it will have output.
- Note 3: When connecting 3 sets of batteries in series, please ensure that the voltage of each set of batteries is the same. If they are different, please fill each set of batteries separately and use them in series. In the discharge test, the battery with a fast voltage drop is a poor battery.
- Note 4: Requires activation every time.
- Note: Do not mix good battery and poor battery! The closer the capacity/internal resistance of the 3 batteries is, the better! (The effect of 2 good batteries + 1 poor battery = 3 poor battery usage).
Description:
The main IC uses the original rich crystal imported components. With overcharge, over discharge, over current, short circuit and other protection functions, for a variety of shapes of various shapes 3.7V lithium battery. It adopts rich crystal protection IC, high quality MOSFET such as VISHAY, AOS and IR, FR-4 low temperature coefficient plate, excellent design, fine workmanship and comprehensive test. It is small in size and suitable for many occasions requiring high integration and low cost. It can meet various performance requirements and ensure the safety and reliability of the battery pack.
