Description

  • Designed for Raspberry Pi series, compatible with Raspberry Pi 3 / 3B+ / 4B, etc.
  • I2C bus communication, monitoring the batteries voltage, current, power, and remaining capacity in real time
  • Multi battery protection circuits: over charge/discharge protection, over current protection, short circuit protection, and reverse protection, along with the equalizing charge feature, more safe and stable
  • Onboard 5V regulator, up to 5A continuous output current, more sufficient power source for Raspberry Pi

    FAQ

    Question: Why the HAT doesn’t work after re-connect the battery?
    Answer: You need to connect and press the boot button to activate the protective circuit.
    Question: What is the battery life?
    Answer: Without other devices and in standby mode, the battery can feed the Pi for about 3 hours after fully charging.
    Question: Why is the capacity value changing all the time and it is not accurate?
    Answer: The capacity is measured by the battery voltage, it is higher than the actual value if you connect the power adapter for charging. The expected voltage when fully charging is 4.2V, however, the actual voltage will be smaller than it.
    Question: Why is the current value is negative?
    Answer: Negative value means that the battery is discharging and powering the Pi.
