Post Is there really no simple solution??
Hi all,

I'm new here and very frustrated...

I've been searching these forums and Google looking for a simple way to power my camera (Nikon D300s).

I found the EH-5b for indoors (expensive but works), but I can't seem to find a solution for outdoors without having to hack something. I have a power grip for the D300s, but that will not suffice.

Is there no power supply out there that can safely be connected directly to my camera (or even using the EH-5b adapter) without hacking a battery or risking my camera being fried??

I'm also looking for a solution for a Nikon D3s that I rent every once in a while, if there is a genius solution hiding here somewhere...

Ideally it will be light and safe to travel with overseas, but at this point I'll settle for a 10lb solution as well...

Thanks for your time and all the valuable info shared on the forums!

some questions
1 what you understand with outside? in the mountain's in your garden??
2 your will use a external Battery, power from the car, or you have 110V (or 220V depend what Country your are ) ?
3 for what you need so much ?
i have a Battery-grip with 2 Batteries and 2 spear Batteries, this its for all day sufficient power.
i will use this https://www.sparkfun.com/products/527 ( or similar ) with a 12V external Battery . ( its a little Project to put this in the Batteriegrip, stil not finish )
its simple and are so much info in guugele :lol:

I'll do my best to answer your questions, I hope I understood you correctly.

1. By outdoors I mean far from a place where I can connect my camera to the wall with the EH-5b.

2. Not sure I understood this one. I currently have a power grip and a spare battery, but this is not enough. I will order the EH-5b but that will solve the problem only when I'm indoors. I do not have an external battery (that's what I'm looking for) or a way to connect the camera to the car. I'd prefer a solution that will not involve my car battery as I might not always have my car with me. It's 220V where I live.

3. I need the battery for time lapses. Especially at night.

I searched Google, but all I could find was methods to hack a battery and similar methods. I'm asking if there is a "plug & play" product out there. A battery that I charge and then simply use the EH-5b to connect it to my camera?

How long do you plan to be shooting and what kind of timelapse?

I was able to get about 3,000 shots from my D7k before the battery would die out. shoot manual, turn off any VR, and no AF or image review. That also included about 700 astrotimelapse frames.

you should be able to go several days with a grip and extra battery

Thanks for the reply, Jack!

Right now my biggest problem is with the night time lapses (stars, milky way, etc).

I shoot manual, turn off VR and all other in camera settings which could save battery. Still, the D300s will give me about 7 hours (with the grip) and the D3s, which is really much better for astro photography, will last only 3-4 hours.

I have a spare battery for the D3s but obviously there's no grip for it, and changing batteries causes a noticeable jump.

Daytime time lapses are less problematic and I can probably get around 3,000 shots as well, but ideally I'd like to have a solution if I go camping for a week or so and can't keep charging batteries.

Post Re: Is there really no simple solution??
you have a 8x AA batteries battery holder for this Batterygrip?
i dond think are a plug in play solutions.
i see this are 7.4V Batteries .
http://www.dimensionengineering.com/products/de-swadj
or
http://numato.com/lm317-variable-voltag ... r-breakout plus this http://www.robotshop.com/dimension-engi ... swadj.html

this you can mount in the batteryholder and mount a little 2.1mm barrel-jack connector for connect the battery like a 12V

http://www.robotshop.com/productinfo.as ... lang=en-US
or
http://www.robotshop.com/productinfo.as ... lang=en-US

Battery's are here
http://www.ebay.com/sch/i.html?_odkw=Re ... y&_sacat=0
and you can connect multiple batteries parallel ( ok all full charged, not 1 battery 1/2 and another full, because the full battery will charge the 1/2 empty (full) battery )

i hope this help.

Been lurking a while, thought I'd chime in here as I've been looking for a solution like this for a while and finally found one that works with nikon products. I'm not sure this will work for a D300s, but this is the first solution for an external battery pack that I've found.

http://www.switronix.com/products?page=shop.product_details&flypage=flypage.tpl&product_id=191&category_id=45

It says it's for the D7000, D600 and D800. Essentially any nikon that uses an en-el15 battery. Has a dummy en-el15 battery on one end, and regulates voltage to accept any p-tap battery such as an anton bauer pack, like the Dionic 90 (90Wh). A little on the expensive side, probably going to be at minimum 300 or 400 for a basic solution from what i've seen since it requires a p-tap plate adapter as well as a battery pack on top of the regulator cable.

Of note though, I haven't actually used this or had any experience with it, but I'm looking at ordering one soonish.

Hope this helps though.

Thanks Eric and Dirk.

This is the closest I've seen to what I am looking for, but won't work with either camera I use... :(

I asked B&H about this a few days ago. The guy suggested I look into connecting the EH-5b to a generator..

I use Canon, not Nikon, but I think the same thing would work.

I got some dummy batteries and a voltage regulator. I did not get this one, but I like that this one has a voltage readout built right into it.

Here is the dummy battery for my Canon cameras. You will need to find the correct one for you.
http://www.ebay.com/itm/LP-E6-Dummy-Bat ... 0975674463

I use a 12v motorcycle sized battery into the voltage regulator.


The regulator steps me down to 7.2v, which is what the Canon wants to see.

I have a little portable meter that I use to check the power before I connect it to the camera.

If you do not want to DIY, Jag35 has a system that you can buy.

Thanks diputs. Sadly, I can't find ready made dummy batteries for Nikon cameras, let alone the two specific models I need.

I also couldn't find a solution for Nikon users over at Jag35.

Looks like Canon users have a lot of advantages when it comes to time lapse photography.

Hi,

I use these http://www.teleskop-express.de/shop/pro ... --60D.html in my Canon and they works great.

simple solution kind of.......

I have been using this for years with my nikons, since 2007

quantum cd100 cable will work on d300, d700, d3, d800 with adapter

just get an adjustable dc/dc converter, set to correct voltage and add any 12v source.
I just use tamyia connectors and whatever 12v battery I have. A 4500mah will last all day, I always keep a battery in camera as well.

I sometimes run up to six cameras at once so, I am slowly moving to a dtap solution with some switronix or anton bauer batteries, but that's
quite expensive.

An even simpler method is to get the big lithium batteries for model cars and what not. They are 7.4volts just like the camera battery. I wire a plug to it that fits the plug where the fake battery that comes with the camera charger (for the 5D2 its the ACK-E6) attaches to the charger itself. You need a special charger for that kind of battery but it runs the camera all night and then some, then recharges in minutes. I tape the battery to the tripod handle along with the intervalometer.
