    Answer these questions...in order...

    1) What is the NOMINAL voltage of a standard AA NiMH cell (not the peak voltage, not the depleted voltage, not the voltage you read from the meter right now, but the NOMINAL voltage according to any NiMH, or NiCAD datasheet)?

    2) How many cells do you have in your pack?

    3) Multiply the number of cells in your pack by the NOMINAL voltage of each NiMH cell in that pack. What is that value?
    You are asking the wrong questions. There is space for 6 batteries which amounts to 7.2Volts as you have already figured out. Adding two batteries is not possible here without creating a new adapter. And I am talking about creating in an injection molding sense.

    If you got that opportunity you are lucky.

    So, replacing the 78xx series regulator by a LT 1083 ( 7.5 A )could be an idea ... instead of adding cells.
    Yes. As the one mentioned requires additional components to adjust the voltage a new circuitry is needed. This is what I desire to avoid.
