    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.

    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.

    I can not say for sure but I think that battery pack could be a Lipo pack(Lipo means Lithium Polymer)and they are also used in RC Cars a lot and Lipo packs are not good news if they get dropped or over charged or over discharged and can go up in flames really fast,try and find a Nimh or Lithium ION battery pack as it will be much safer.

    I use an RC battery with my Sony s6300 on occasion.

    Would a external battery pack and a dummy battery work?
    That is a MIMH pack from what I can see what I'm talking about is a Lipo pack.
    Could a person use a Lipo pack safely with a camera yes they could but if it ever did decide to just go off and catch on fire and it was in your pocket I can promise you that person would be ina world of hurt.

    The problem with Lipo packs is like I said before you only need to dent it or over charge or over discharge it and then you have problems,that being said how ever almost in every case if a Lipo pack has been damaged the whole pack will puff up like a balloon or at one cell will and that's when it get's dangerous.

    I have seen a new Lipo pack that was used only 3 times and when it was being recharged it went up in flames,the pack was never abused and the charger that was being used was used many times before and after that pack so the charger was not the problem,also with Lipo packs if you are charging a pack that has been over discharged the charger will only put a slow charge back into it and that was not the case with the pack I was charging.

    The all being said are Lipo's safe for the most part yes they are very safe but at the same time I'm not sticking one in my pocket because I have seen to many go up in flames in RC cars as well.
