Lithium-Ion Charger (2)

In the December issue we’ll describe a fancy Li-Ion charger based on a specially designed IC and boasting many bells and whistles. However, it can also be done in a much simpler way, provided you are prepared to work carefully. The latter is particularly important, because we will point out again that charging Li-ion batteries with a voltage that is too high can cause explosions! In this respect Li-ion batteries are not the least comparable with the much less critical NiCd- or NiMH-types.
