Can I connect 5V DC power from a USB power supply to a 3.7V
Yes, you can connect 5V DC power from a USB power supply to a 3.7V BMS, but the following points should be noted:. Voltage matching: The USB power supply BMS output voltage is 5 volts, while the original battery is connected to 3.7 volts. This means that the voltages do not match. In this case, you need to make sure that the BMS and associated circuitry can
