Note:Do notinclude18650 batteries, Please Buy alone.
Notes and tutorial links
The pin header interface includes 5V voltage output, 3V voltage output and IIC output.
Note 1: When mounting the battery for the first time, you need to pay attention to whether the LED is on. If the LED is on, it means that the corresponding battery is reversed. Do not charge the battery if it is reversed.
Note 2: There may be no power output when the battery is connected for the first time. You need to press the BOOT button on the circuit board to activate the battery protection chip to have power output.
Note 3: Use the power supply configured by the product to charge. Using other power supplies may cause the product to be damaged if the output power ripple is too large and unstable.
Note 4: If the positive insulation pad of the battery is broken, it is recommended not to continue to use it, which may cause a short circuit and fire. When removing the battery, do not use a screwdriver to pry the positive pole of the battery, which may cause a short circuit, and pry the negative pole of the battery.

No alimentará un pi 5 desde el arranque. El pi 5 entra en un estado de bucle ya que el voltaje no es lo suficientemente estable. Pi 4 debería estar bien. Muy decepcionante usé células de 18650 pre probadas y una la fuente de alimentación suministrada.
