Fun hack! Do you have a line on cheap LiFPO4 or is it just to get a longer run time between swaps?

- p1mrx 7y agoI prefer not to use disposable batteries for environmental reasons. But with NiMH, a light designed for 3V will be dim, and an LCD will have low contrast. In that sense, the effective run time is zero, so NiMH is a non-starter. I found some AAA-size LiFePO₄ cells, spacers, and a charger on AliExpress a few years ago.
