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?

Hello I have one of your UPS v3 connecter to my Pi. I have activated the Auto UPS feature (on). However, when the Pi is powered off using the poweroff command, the Pi does not restart when power is put back on.

What could be the cause?

After installing the UPS3 and some testing, it seems that the Raspberry pi 4 will not boot up if it's powered down (poweroff) and the power is back, except if the battery is dead or removed in the mean time. Is the behavior correct? Based on the description, as soon as power is back, the Pi shoud boot up normally

I've ordered UPS 3 from aliexpress u-geek workshop store.

In the package I've received the UPS 3 and a small plastic bag with two PH 2.0 2-PIN cables and two very small radiators(these are not for raspberryPI as they are very small and it's almost the size of the microchips on the ups 3 hat)


Besides that I have one more question. Sometimes the board makes some coil whining noise, is this normal?

Battery fuel gauge chip MAX17048: Uses I2C addresses 0x6C and 0x6D, per the Maxim datasheet. However, your smartups.py code has "MAX17048_ADDR = 0x36". Which is correct, and how does this work?

these two are the same thing, It's just that the address is a little different; One is adding 0 before the address, and the other is adding 0 after the address. The program is to use 0X36, in the system, the ADDR is 0x36

I need some help for using your UPS3 with other HATs in the same system. What are all the GPIO pins the UPS3 uses? Studying your Wiki and Github info I find:

- LED brightness (control): GPIO 18 controls LEDs, and this can be changed to GPIO 12 (either provides Pi PWM0). I must also change the "DI" strap on the UPS3 board, next to the "POFF" strap to use GPIO 12, correct? - Power off control: Using the UPS3_power_off_guide, if I strap connect GPIO 6 and then drive GPIO 6 high then the UPS3 immediately turns off power to the 5V output, correct? - I2C port used: Uses Pi I2C1 interface on Pi P1 connector pins 3 and 5, correct? - Battery charger chip BQ25895: Uses I2C address 0x6A, correct? - Battery fuel gauge chip MAX17048: Uses I2C addresses 0x6C and 0x6D, per the Maxim datasheet. However, your smartups.py code has "MAX17048_ADDR = 0x36". Which is correct, and how does this work?

- Are there any other resources on the Pi P1 connector that are used, so that I can avoid conflicts in my board design?

If I supply a fixed, constant 12V to the USB-C connector will this cause any battery over charging or more wasted power/heat in the UPS3 board? Is there an advantage of 5V versus 12V power in?

Hi,It can support 12V/9V/5V input, will not overcharge the battery.

The charging current of the battery is dynamically adjusted according to the battery status.

Yet another geekworm ups hat that does not do what it should..

With the switch in UPS mode, if the pi is shut down it will not power back up again if the input power cycles. Completely useless. I have to make some sort of monostable oscillator that gives me a 2sec pulse to power back up in normal mode to get any use of this.

If you want continuous power supply, you need to turn on the 【auto 】switch.If you are using UPS mode, the auto function cannot be realized. Please understand.

Hi

Hope you can help me with this. I have an UPS3 board on a raspberry pi 4 and a 3,7v 6000mah battery attached. It works. but there is a red led for ac input power and a green for battery input power. first they both lit up and after a couple of day the red ac light began to blink. what does this means? If I pull the ac power off and attached it again it will light up steady and then after a couple of days it will start to blink.

best regards

Hi, The red light flashing is an Alert, which is usually caused by a malfunction of the charging adapter. At this time, please unplug the power and plug it in again.

hello! before shutdown, i need to perform an action on the RPi..

can the switch off button's message to Rpi be edited in order to perform this action before the acutal safe shutdown?

let's say: 1) switch off pressed 2)message sent from UPS HAT to Rpi in order to manage an additional/external operation from the Rpi (in my case is safely shutdown a device from a Rpi's Gpio) 3)Rpi safe shutdown

greetings

Given that the Voltage of this UPS Hat is specified as 3.7V could we also use LiFePo4 batteries rated at 3.6V?

Most other HATs charge up to 4.2V and that's way to much. We're just 0.1V above that ... so would it be save to use LiFePo4?

I really don't trust Lithium-Batteries at all for that use-case ...

Hello,We do not recommend use 3.6V, it needs to use 3.7V

Given that :

- We use I2C to track the charging status and detect a power failure - We set the AUTO UPS switch to ON


1 - We detect a power failure 2 - Battery is now used and everything is alright 3 - We decide to shut down the RPi 4 - During the shutdown phasis, the power is back


Q : What happens at 4?

I think that actually, the RPi will just keep on shutting down normally but never powers ON again until a new power failure + power recovery cycle occurs. Which would be quite a problem and would defeat the purpose of this UPS device.

Hi dear ,Glad to receive your message 1. The battery power is decreasing. It may be the voltage change during charging. The measuring chip is recalculating the power. The light is red to indicate that it is charging. Check the power situation after a while. If the power keeps dropping, try another power cord. 2. The automatic power-on function means that when you turn on the "auto on" switch, when the external power supply is connected, the Raspberry Pi will be powered on. The switch button controls 3.

The UPS hat stops charging the battery once the main power is reconnected. If I shutdown the raspberry Pi and restart HAT either with push button or with the auto-power switch, only then SOC% start increasing in the log(battery really starts charging). Details below:

Steps & Observation: 1. Raspberry Pi powered via HAT and battery is charging, log file shows SOC% going up. 2. Power is disconnected from HAT USB-C 3. Raspberry Pi still remains operational as expected. log file shows SOC% dropping as expected with status:discharging 4 HAT USB-C is supplied power again (doesn't matter on the auto-power switch state) 5. Raspberry Pi still remains operational. log file shows:

smartups.log: INFO Input:Connected , ChargeStatus: Charging , SOC:44%. <== SOC continue to drop

It turned out to be the power supply issue. Replacing it with recommended 18W+ power supply with PD or QC fast charging support resolved.

This Hat helped with the power problems I had with my Pi setup. I'm very pleased so far. I am unable to get the battery test to work, ill try to figure that out soon. The only thing extra is, that I would have liked to have solder pads for input power along with the current connector. Very Nice... if you could point me to how to fix the batter level indication, I would be appreciated. Also if there is a more detailed user manual than the single sheet. Love the Hat !

I will reccomend this to a few Pi using friends !
