I am planning to make a battery pack, by using rechargable batteries, that i can use to power my DC-coupler for my DSLR camera.
(Ref. Image)
On my original camera battery it says 7.4V 1.2A but i was measuring 8.03V.
So I was searching for a voltage regulator with 7.4V output, but I couldn't find one in my local electronics store. Thats why I want to use an adjustable voltage regulator with as less dropout voltage as possible, so i can use 9V batteries or a couple of AA batteries ( that adds together to 9V ). I know that i need keep the unbalance that occurs when putting batteries parallel to add the current, in mind. But thats another problem for later
So my question is: How can I get to 7.4V by using batteries and a circuit that regulates the voltagr down from 9V ? Should I use adjustable voltage regulators ? And if so, how do I need to use them / build the circuit to power it with batteries ?
