RE: Care Package 5.0: What I Plan to Do With All Those Lithium Batteries
It's bad to put them in parallel (as in a power bank ) because when it's fully depleted, the safety circuitry stops it at an average voltage for all 4 cells
I am not that much of an electric Man but it seems the energy of all the batteries is not used to fullest, so use them individually instead, the above said lamp is really the best thing you can make using this battery.
Yeah, at first I was just going to put them in a single cell power bank kit. But then I thought they would like to have light too, and went looking for 18650 based flashlights you can charge a phone with. But then I thought, "where will they get electricity for this?" and found these solar lanterns that seemed to solve all those problems.
Man its pretty amazing
