  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Holy Fong!!!

With batteries like that you can run your camera, the sound dept., the video village and jump start your car!
 
How much juice is 140 Ah? What can I compare this too?

I was thinking of getting 2 batteries but maybe I should save my pennies and just get one based on that response alone
 
that's a lot of juice, holy crap, 25 HVX 5400 mah batteries.. Even if the Red ate 5x the amount of power than the HVX, you would still get over 10 hours of juice per brick.. Maybe I only need one..
 
I think it's 140Wh, but I'll check. Maybe Stuart knows for certain.

You beat me to it Stuart!

Other V Lock Batteries?

Other V Lock Batteries?

So would my V-lock Steadicam PowerCube batteries (basically IDX Endura 10s batts with capability of higher amp outflow to drive high speed film camera when necessary) work fine? I have 4 of those nice batteries plus an IDX 4-up simultaneous charger that would be nice to use not only when flying the RedOne on Steadicam but also for directly connection to the V-Lock plate when shooting handheld and on a tripod. Will that work?

No your not.
I was just joking about the fact that when the price list was first put up it said 140Ah (ampere hours) which would have been a very large battery indeed!

Speaking of batteries, what voltage does the camera require?
 
Watt Hours - Battery time

Watt Hours - Battery time

Watt hours are the number that is most useful as it describes the real energy in the pack. You get watt hours by multiplying amp hours times the voltage. So the HVX use 7.2 volts times 5.4 Ah = = 39 watt hours. So the RED battery is only about 3.5 times the power of the HVX batteries. RED with a hard drive and LCD will probably draw 40 to 60 watts and I wouldn't be surprised if it was more as they probably have a pretty serious processor in there - possibly even something like a core duo type of chip. Anyway 70 watts would mean you get 2 hours out of a 140 watt hour pack.

The hard drives could spin down between takes. That should save a few watts. I wonder what sort of power saving features the on-board processor(s) will have. Just de-bayering for viewfinder, etc. output should use much less computational power than doing that plus simultaneously doing REDCODE compression, so conceivably the camera could also save a fair bit of power between takes by also clocking down the processors, if they support that sort of thing.
