[QUOTE="HarryN, post: 1007761, member: 69773"] The best known Li ion cell is the 18650 size, which is nominally 18mm diameter x 65mm long. With the protection circuits, they can be physically slightly longer. Charged voltages tend to run about 3.5 - 4.2 volts, depending on the exact chemistry used. There are AA size Li Ion cells, but they are also similar voltages vs. the traditional AA cell which is closer to 1.2 - 1.7 volts. There are some D size Li Ion cells on the market, but for safety reasons, the FAA restricted the amount of Li per cell, so I don't know if these really perform as expected or not. [/QUOTE]
