Product selling point:
1. the use of high-quality materials, product quality is guaranteed.
2. Small size, high power, high efficiency and complete protocols, which are basically supported by mainstream open protocols.
3. The module is suitable for 3.7V lithium batteries, including polymer, 18650, 21700 and other lithium batteries; Make sure that the batteries are not aged, and the batteries can be connected in parallel but not in series.
4. The module is small in volume and limited in heat dissipation area, so it is normal for high-power output to generate heat.
5. The products are widely used in various industrial DIY occasions.

Precautions for use:
1. The battery and motherboard wires should not be too thin, but as thick as possible. Fast-charging board requires 10A current and non-fast-charging board also needs 7A current. It can’t be too long, and the interface needs to be welded.
2. The batteries can only be connected in parallel (there is no limit to the number of parallel connections), but not in series, which will burn the motherboard.
3. In normal application, the battery must be welded, (twisted wires will lead to insufficient power supply), and the battery will burn if it is connected to the motherboard in reverse. Be careful. The line should be as thick and short as possible.
4. When connecting the battery, make sure to connect the 3.7V battery, not other batteries. Make sure that the batteries are not connected in series, otherwise the board may be burned if the battery terminal access voltage is higher than 4.5V.
