Batterys in parallel and in series?
I am designing a circuit with some space restrictions. Unfortunately i can only put 3 AAA batterys in it. I need at least 1.8 volts for the circuit to be operational, so 2 AAA NiMh batterys in series is rated 2.4 volts. If i have this can i also add a single parallel battery, for added Mah. The diode i will be using has a forward voltage drop of .33v at 1 amp. These batterys will have a load of about 500 Ma. Will the (very bad) schematic i have work? Also, will the output voltage of the batterys be somewhere around 3v? One more question, will the load be shared between the batterys?
