Battery options for running E700 camera only?

Post by CroCop » 26 Jun 2017, 15:56

I'm using a E700 camera and a vf-2c viewfinder.

The viewfinder is running off the three batterys which plug straight in.

Since I'm not running a 3.5" screen, which eats more power than the viewfinder, what is the smallest type of rechargable battery I can get away with to run the camera only, for around 8 hours of use?

I just want to make my NV setup as compact as possible basically.

Thanks very more for any info and advice.

The E700 will operate quite happily down to about 7 volts, so two lithium ion rechargable batteries wired in series would work. A couple of CR123 rechargables might stretch to 8 hours.
Do you get 8 hours out of the 3 AAA batteries in the VF-2C ?

Thanks,

To be honest I have not had much time to use the viewfinder yet, so cannot say.

I need to add a proper on/off switch to it first, and reduce the length of the E700 AV/AC cable.

Then hopefully with these smaller batteries I can build a decent little monocular type device (E700/VFinder/Battery), which can also be fitted onto the back of a scope.

Be aware that the camera lens needed for a spotter is very different from the lens needed to mount the camera behind the scope
For a spotter, a 50mm lens or longer is normally used to get a narrow enough field of view so that what you are looking at can be illuminated evenly
If the camera is fitted behind the scope then you'll need a 12mm or 16mm lens to get a decent view of the reticle.
Have fun

I use a 9 v. block battery to power my e700. Aldi 9 v. blocks are cheapest and run for about three hours at one go.
Instead of a screen or viewfinder I use Zeiss Cinemizer videoglasses. I also use a spotter with these glasses at the same time so I can instantly choose between spotter and rifle setup. The Cinemizer glasses allow me to shoot 'around the corner' if I am in a cramped position in a high seat, like shooting over the right shoulder.
The battery cases are cheap through Aliexpress and come with a switch to turn on and off. The spotter has a push button on/off.
Here are some pics.
If you are interested I can make some detailed pics of this setup.

I use the same battery holders and keep at least one spare with a new battery in my bag. This way there is no risk of damaging the cam.

Guys thanks for the link to those 9v battery boxes, perfect for what I needed, with the DC plug to, just ordered one. Especially after what you say about one touch reverse polarity blowing the camera.

Nice one.
