UPS Not Providing Enough Power

General
1

Hi.
I use the Sunfounder UPS on my PI 4 to run Openhab. My system reports: Your Pi’s power supply or cable is not good enough to supply power without an under-voltage event occurring.

I plugged directly into my 120 volt power supply to correct the issue. My question is do I need new 18650 batteries to solve this. Does anyone know?

Thanks

We suggest you use the official power supply of Raspberry Pi.
