  1. Li-ion batteries are so much better than AA batteries, with few of them we can get the energy of several AA my question is, would all the mAh damage the circuitry of ordinary toys and stuff? How can I use 2 3,7 v 1000mAh batteries to replace 8 AA batteries? what circuitry is needed for diminishing the amperage and rise the voltage? ------------------------------------------------ top ringtones, mp3 ringtones download, bollywood ringtones
