Product selling points:

1. Using high-quality materials, product quality is guaranteed

2. Small size, high power, high efficiency, complete protocols, basically supports all mainstream open protocols

3. The module is suitable for 3.7V lithium batteries, including polymer, 18650, 21700 and other lithium batteries; ensure that the battery has not aged, and the batteries can be connected in parallel but not in series.

4. The module is relatively small in size and has limited heat dissipation area. It is normal to generate heat due to high power output.

5. The product has a wide range of applications and is suitable for various industrial DIY occasions.

Precautions for use:

1. The battery and motherboard wires should not be too thin, but should be as thick as possible. Fast charging boards are required to be able to pass 10A current, and non-fast charging boards are also required to be able to pass 7A current. It cannot be too long, the interface needs to be welded.

2. Batteries can only be connected in parallel (the number of parallel connections is not limited) and cannot be connected in series. Series connection will burn the motherboard.

3. For normal application, the battery must be soldered (twisting the wires will cause insufficient power supply), and the motherboard will burn if the battery is connected reversely. Be careful. Keep the lines as thick and short as possible.

4. When connecting the battery, make sure it is a 3.7V battery and not other batteries. Make sure the batteries are not connected in series, otherwise the board may be burned if the voltage connected to the battery terminal is higher than 4.5V.
