Powering with 18650 Li-ion?

Hi

Do you have any experience in powering Pisound with Li-ion batteries and boards / hats such as:

?

I would think you would have to go for a pretty powerful Bank as I am if not mistaken PI and Pisound requires 3A

The Li-ion batteries should provide enough current to power the Pisound & Pi. The 2nd board option seems better, as it’s placed under the Raspberry Pi - the first one probably wouldn’t fit below the Pisound, as the audio jacks are underneath the board and would hit the batteries.
