    Would a external battery pack and a dummy battery work?

    I was just wondering if this rechargeable 20,000mah battery bank/pack would work with the EP-5A adapter?

    No. The EN-EL14 battery is 7.4 volts, and that system is 8.4 volts.

    However, many battery packs used for radio-controlled cars (like the good ones sold at hobby stores) are 7.2 volts.
    Don't mind me... I'm out roaming around somewhere between Zone III and VII.

    Welcome aboard. Enjoy the ride.
    We look forward to seeing more posts and samples of your work.

    This unit is rated at 8.4 V and the EP-5A is 9 V. I would doubt it.

    Oh ok, I thought it was 8.4. So then this would work?

    Wait, is it 9v or is it 7.4? I thought I've seen on the internet that it's 8.4

    Ok, so what kind of battery would I need that has that much mah? I'm trying to get to close to 20,000mah.

    Nikon's website has the battery at 7.4 volts.

    I don't see much reason 7.2 won't work. But 20,000MaH? Dang, that's HUGE!!!!

    If'n I really need that much capacity, I'd consider stocking up on 3.7v 26650 LiIons with solder terminals and building my own pack. Get name brands. Current technology has the max output at around 5000 MaH. So 4 of 'em wired in series/parallel would get you there.

    My guess is you're wanting to run the camera a long time (ie, time-lapse). So current flow won't be a problem. But if you're going to run them 'hot' (high current), I'd go 8 or 10 batteries to really keep the heat down.
