I tried several different LiPO batteries and 5V circuits, always ran into two issues: 1 was the low voltage cutoff as mentioned above, not really a issue if we could get long battery life, but 2 was the way the circuits operated caused a much higher drain then expected and the ~500mah batteries only lasted about 3 days as the 5V circuit was always on. I found Nimh N-cells much easier overall for a recharagble solution.

Hello Martin
The big deal with the current drain is the quiescent power of the used chip on the booster. Your board needs in 3 days 500mA. That are 7mA quiescent current. My best one takes 18uA, thats 390 time less.

For the next weekend, I publish my table with all the tested chips and boards.
