Battery options for 82143A printer

[Hans-Peter]

My solution has a 3000mah LiPo single cell with low voltage protection. A small charging module with a micro USB connector and a 5V step-up DC converter with a low quiescent current.

You can use 2-3 single cells in parallel, but with exactly the same capacity.

           

The first variant was also with 4 AAA cells and a small wooden beam. I still have to look for it to take a picture.
