Rechargeable Batteries
Hey everybody!
Trying to save some money and I am in need of some advise, leads, tips or what-have-you on AA, 9V, D and other rechargeable batteries and where to buy them. Applications vary from guitar amps and pedals that I will be building. Perhaps 3 18650s for 11.1 volts? 12v dry or gell cells... to flashlights and other small electronics. I need to do it as safely as possible, keeping in mind that some of these things like to mimic fireworks. Any help or thoughts would be most appreciated.

18650 cells are 4.2V at max charge and nominal charge is 3.7V. dont let them get below 3.2 and in most cases 3.5 is the safe cutoff.
so 3 cells series will have a max of 12.6V and recharge when the pack drops to 10.5V. This made me think i need to make a pack to drive my micro cube... mmm got a few lying around if i use 6 in a 3S2P i should get a lot of life out of it between charges.
