This is an interesting solution. Vmount to dual npf pries with power meters and dtap.

Hot swappable external power that's pretty cheap to run all daylong.

Have one and works fine, but the F970 batteries are not hot swappable as they are internally connected in series. Disconnect one and the rig loses power.

Oh that sucks, kind of defeats the purpose of mounting two batteries for me. 

Do they both discharge at the same time too?

For example, if 2 batteries gave you 4 hours, could you run it for 2 hours, change 1 battery and still have 4 hours to go?

They discharge at the same time as they are just connected in series to get the 14,4V needed (2x7,4V).
You should change them at the same time and only use equally charged (and same capacity) batteries together.

Guess the only advantage is that F970 batteries are cheaper than V-mount batteries and some people might have already lots of them.

Yeah, but even still, I think you'd be better off with one of the smaller sleds that take 1 battery. That way you can just have 3 on rotation and shoot all day long. 1 charging, 1 charged and 1 on the camera. Thanks for the info!

Hey guys,

I have been reading through this thread and I am still looking for a lightweight charging option. I stumbled across this dual battery pack from Tilta for two 18650 batteries. It says it will provide 8v through the dc output, which should be enough to power the camera if attached to a dummy lp-e6 to dc barrel battery? Or am I making any mistakes here?

Not particularly set on the Tilta pack, but in terms of price and mounting options it seems to be the best one for 18650 batteries I have seen so far, or do you have other recommendations?

Best,

Paul

this should work, just need to add the right connector and the batteries.

the batbox4k in this thread is very nice, but I did not get a response yet. So I might experiment with the 2.5 euro solution above ... Should give an extra 2h-2h30 on top of the internal battery. 3h useful battery life with a still compact solution would be great !

It's a lot smaller than v-mounts of the same capacity and has loads of dtaps for lights, monitors etc, as well as a dummy battery. It seems very versatile to me, and isn't much more than a v-mount. 

You do lose the ability quickly swap though, and of course with V-mouny you have more capacity options.

vmounts don't have to be big.

i don't really like the shape it has, must be ok on a tripod but handheld... sure it has a lots of connectors, just the shape doesn't feel right to me

I am thinking about going with this core swx battery, since I already use a smallHD focus. I would power the monitor and the camera from this battery, by going to the 12v of the camera from the battery. Do you think this would work? I read earlier in this thread of some concerns of powering a monitor and the camera the same time form the same source, but this seems to be a different type of config
