Hello all,
Im trying to figure out or determine what batteries to use for a project and how to charge them.
I need these batteries to supply enough voltage and amperage for:
GLCD
TOUCHSCREEN
PIC
LEDs
External SD
Now i dont know but to me that too much and will die on a 9v battery to fast. so i was thinking instead of using a 7805 i would just use like 3-4 rechargeable 1.2v - 1.5v batteries and make a desk charger for it. Now the thing is i dont know squat about batteries and how to charge them and how to calculate ho long they would last on a single full charge.
That is why i am asking you people lol (guys/gals (if any(no offense)))
Should i use small AA type? C,D type? How do i know which are best.
Please if you recommend a battery... explain why so at least i can learn this stuff lol.
Thanks again.
