Raspberry PI UPS HAT (V2.0) DFR0494
adelvalle62 2023-01-05 15:35:34 514 Views1 Replies I just receive 4 pieces of the Raspberry HAT DFR0494 but with battery at 50% if we disconnect the main power there is only 10 seconds of backup power from the lithium battery 3.7VDC 2000mA-h. Any idea if we made anything wrong?
The Raspberry is a 4B version with 8GB DRAM and SD CARD 64 GB with a RS485 dual serial interface with another HAT
Thanks in avance

Hi!
Is this the case for all DFR0494? Have you tested with another Raspberry? Can this Raspberry 4B receive DC power through the GPIO interface? Does the same thing happen when other devices are removed?
