FAQ

Q1: Customer feedback 1: I have an issue with UPS hat 3. I tried to use battery from the old tablet and pack of cells, but none of them work well and the raspberry is turning off about 0.5 to 1 second after disconnecting the power. I'm not sure, that it's problem of batteries or hat itself. Do you have any suggestions what is wrong? Could you suggest which batteries works best?

A: I guess, I found the reason why the UPS hat is not working properly. My raspberry pi is overclocked to 2.0GHz and also has increased voltage. When I use the defaults voltage and clock values in the configuration file it works better, but still I think my batteries are too weak. I'll do more tests and let you know. Currently, I find it important to note that overclocking is bad for the condition of the UPS 3 hat.

Q:Is it allowed to supply 12VDC directly to VCC and GND wires of the USB-connector ?

A: Yes, it is ok to use 12VDC directly.

Q2: We want automatic shutdown when the external AC power supply is disconnected, is possible?

A： Yes. you can program a script to get this function. Example (The following is a pseudo code):


while (1) {
  // invoke the API to get AC PSU status: connected or disconnected
  int disconnected_flag = getACPSUStatus(); 	// please refer to the user manual to achieve getACPSUStatus function;
  int battery_voltage = getBatteryVoltage();    // please refer to the user manual to achieve getBatteryVoltagefunction;
  
  // You can make your own actions based on disconnected_flag and battery_voltage, you can only select one condition also
  if (disconnected_flag) {
    // execute linux or software shutdown command
  } 

  sleep(10);
}

Q3: How to restart the pi board when AC Power supply is connected?

A: Please enable 'AUTO POWER ON' or 'AUTO ON' function if you want restart when the AC Power supply is reapplied.

Q4: Why the Raspberry Pi can't turn on after install the UPS3?

A: Please pay attention to the UPS3 board installation directions, this is wrong.

Hi there. What did I do wrong? I bought four smart UPS HAT V3 and LiPo Batteri 3.7V 3000mAh batteries. Now two has stopped working. Before I unpack the last two, I would like to know what I do wrong! I have done the following: - Attached the battery to the UPS HAT. - Connected the Raspberry PI power supply to the UPS HAT - Left the HAT charging for a number of hours. - Attached the HAT to the Rapberry PI 3 Model B - Schwitched the AUTO UPS to ON Then PI booted up as expected and every thing worked as expected. The PI kept on running when disconnecting the HAT from the power supply. - The PI and HAT was then mounted in a rack

After a couple of days, the PI “disappeared” from the network. Connecting the PI with the HAT still mounted) to a console, showed that the PI was rebooting, but never managed to boot completely, before re-booting again. Connecting another power supply directly to the PI made the PI boot up and start running. But when disconnecting the PI, the HAT could not keep the PI alive any longer.

Any ideas what has happened to the two UPS HAT’s?
