The battery and motherboard cables should not be too thin and should be as thick as possible. The fast charging board requires a current of 10A, and non fast charging boards also need a current of 7A. It cannot be too long, the interface needs to be welded.</p><p><br/></p><p>2. Batteries can only be connected in parallel (there is no limit to the number of parallel connections), and cannot be connected in series. If connected in series, the motherboard will be burned.</p><p><br/></p><p>3. For normal use, the battery must be soldered (twisting the wires will result in insufficient power supply), and if the battery is reversed, the motherboard will burn. Be careful. Try to make the lines thicker and shorter.</p><p><br/></p><p>4. When connecting the battery, it is necessary to ensure that it is a 3.7V battery and not other batteries. Ensure that the batteries are not connected in series, otherwise if the voltage connected to the battery terminal exceeds 4.5V, it may burn out the board.</p><p><br/><br/></p><p><strong><span style="font-size:20px">Package List:</span></strong></p><p><br/></p><p>Mini fast charging module * 1</p><p></p>
