UPS Not Providing Enough Power

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?
