HELP! Odyssey 7Q record 240fps got problem!

Battery question.

Is it a good idea to completely run your batteries out to 0%, then do a full re-charge? I've heard doing this basically re-sets the battery and re-lengthens the battery life. Any truth to this?

I have a couple of Z-96 LED lights that take L-Series batteries. I might have the batteries power the lights and run them to 0% overnight then recharge. Is this good for the battery?
 
Lithium batteries should in general never run to 0%, and never to 100%.

Quality batteries usually have safeguards to prevent this. In example, my electric Nissan Leaf only uses about 85% of the batteries. Some percentage is hidden by Nissan in both top and bottom, to make sure maximum battery life. My lithium battery in my electric car is best kept within 30% to 70% on a daily basis (we charge it to 80% instead of 100% because we dont need 100% charge normally). However, to preserve battery health even more - its recommended to topple off the battery at the cars visible 100% (still, below actual 100% charge, since Nissan hides the last percentages from us via safety systems) so that each of the battery cells perform similarly.

This last measure is mostly to maximize range as the car will never go further than what the lowest cell can provide. Being 40 or something compartments of cells interconnected, its nice to balance charge these at the 100% mark from time to time. If not, 80% max charge in some cells, may mean that other cells are only at 50-60% charge. This misbalance of cells increases just slightly for each time one charge only to 80%.

Not sure if this can translate to the Sony batteries, but being Lithium, my odds are on that they should not sit at 100% charge, and not in warm areas, and not be surged to 0%.

This is yet another good reason to use a proper Sony charger on a Sony battery, rather than an off-brand model. The Sony chargers & batteries talk to each other via the Infolithium circuit. This allows them to fulfill a maximum safe charge without endangering the battery condition or overall life. Lots of power without danger of the thing catching fire.

As I have always understood it, it is best to top off your lithium cells to what a proper charger will allow. It is also best to do this after as little use as you can reasonably allow. In other words, never run it all the way down and always toss it on the charger. If a lithium battery is to be stored for an extended time, fully charge it first and let it slowly discharge itself over time.

Battery memory is a very different animal these days than what it used to be. With other battery chemistries it made sense to "deep troll" a battery, draining it to the bottom and then "resetting" it with a fresh charge. Not so with lithium.

Like I said before, I have a trio of eight-year old 970 batteries plugging along just fine, although my little test the other day probably didn't do them any favors! My old Aaton NiCads and NiMH bricks never had any life close to that.
 
Hey guys

Just found this thread. I was actually speaking to Sharyn from Westside AV and she mentioned others were having the same issue. The only difference from what I've read so far, is that I don't have this coming from the 2k 240fps (haven't actually had a need to shoot in this yet), but instead from the 4k raw @ 24fps. I don't know if this should be taking less or more power.

I'm using SWIT batteries, as well as a no-name brand. At first I was thinking that it's an overheating issue... as the voltage number goes red and the bg of that icon is yellow. The unit doesn't shut off that much, but more so the camera trigger goes grey and I cannot record. The only thing that works is to disconnect the westside AV for a minute, and reconnect. This gets it going about 50% of the time. So far, I haven't had the unit shut off DURING recording, but it has when in idle.

So yeah, a number of times I've had to pull the plug on the plate, plugin a v-lock and have my AC hold it. The batteries should be fine. I can understand the no-name brand ones having an issue, but I specifically bought a new SWIT for this shoot 2 days ago and my previous ones as well and it's almost unusable.

Yeah, batteries have definetly improved!

The Toyota Prius is now 15 years old (!) and while many of the original batteries in the hybrid cars has gone defect and needed to be replaced, the majority of batteries are still performing excellent after all these years.

And thats with 15 year old battery tech, too!

4k raw 24p is using less power than 2k 240fps. Did you use v-mount battery to power it as well? how did it perform?

Convergent Design plate, although have a hard time believing that Olof's plate is at fault. It really is just a simple soldering job.

When will the convergent design plate in stock? i think i want to get it and give it a try. Getting extra battery palte for myself can use as a backup, and hope for the best it can solve the problem i having then im happy.

I believe we are currently shipping on our battery plates. Talk to your local dealer.

I ordered from B&H but still out of stock. Is there any stock sending to B&H soon? need get it to try with.

BY THE WAY, i tried 200 and 240fps with 2 NP-f970 battery with V-mount, it work perfectly and record till battery run out without problem. So far now it sound good cause for my next few days film shooting it finally can work without fail. But for random shooting still prefer less bulky set up and able to run with one sony battery.

Could you tell me how can your use 2 NP-f970 with V-mount? If you are using a special adaptor, could you post me a link? Thanks in advance.

Here is the the one i bought:
http://www.came-tv.com/camera-lighting-f2bp-vmount-battery-plate-for-canon-5d2-5d3-p-465.html
There are few other brand which is the same function with this battery plate too.
I love using it with my 7Q via d-tap and F&V k4000 led light. It can keep recording 200fps to 0% of battery still no occur any problem. The only cons is i still waiting my tilta v-mount power supply palte for mounting it on the rod. It save my more $$ to buy v-mount battery instead of just using/buy sony NP-f series battery much more cheaper.

Good to hear you find a solution, this works pretty great if you have plenty of F970 on hand.

I forget where I get this pieces of info., but using 2 batteries to double the Volt is inefficient especially 2 batteries have different condition (recharge cycle, remaining capacity, etc.).
I don't have the require electronic knowledge, the battery capacity of 2 F970 using together will result a 6300mAH @ 14.2V, am I right? How does it compares to a V-mount battery with 68wH in terms of capacity?
 
An NPF-970 battery is 47 watts of power. Conveniently enough, that's exactly half of what a standard small V-mount battery is from most manufacturers. They are usually 95w. So two NPF-970 batteries are the equivalent to a standard 95w V-mount or an Anton Bauer 95w Dionic battery. The little batteries also cost a heck of a lot less, making this adapter seem pretty terrific.

But you must be very careful about battery management. Always fully charge your batteries and always use two fully charged batteries together. When power gets low, always replace both batteries on this adapter at the same time. And don't think that you can pull an infinite amount of power off of these batteries. They have internal thermal protection fuses, and will shut down if you attempt to draw too much power at once. I would not want to go beyond about 45w in power, which means that you have enough for the camera and the Odyssey, but not much left over for other accessories. Also note that you will really be cranking hard on your batteries, so expect that they cease to hold charges very well after several months of heavy usage and if you plan to shoot lots of high speed or other heavy draw work, then also figure on buying new sets of batteries ever year. And don't stick anything smaller than the 970 or equivalent batteries on this adapter or you'll drain the lifespan over of them that much quicker. Still, a lot cheaper than buying V-mount bricks.
 
Depend on power % of battery, it will give lesser volts while the power is low. The volts will be given around 13v-16v with it. So far this is my best solution for fs700+ 7q recording while i cant use power adapter for 7q. I didn't meet any problem yet with this set up, the problem is more heavy weight, that's all. BUT i still hoping my 7Q can operate well with one battery, so far using battery plate with one NP-f970, i even will get warning in using 4k2hd while my power of my battery is low. Still waiting original 7Q plate to test it.
 
Maybe Mitch can confirm this, but it seems the batteries go a lot faster when kicking out 4K than 2K which would make sense since 4K is 4x the resolution of 2K

After a long two day shoot this past weekend, I realize that certain L-Series brands make a difference in battery life.

For the 7Q, I've used both Sony 970 and 770 bricks and they don't last long when using 4K RAW or 4K2HD. I think I was getting maybe 1 1/2 hours max out of the 770 bricks and maybe 2 1/2 hours max out of the 970 bricks.

Since Sony batteries are so expensive, I tried the Watson 970 Sony clones off B&H. This past weekend on the 7Q, I was getting over 4 hours on one Watson brick and that's pulling the battery when it got down to 7v. It could have easily went another 30 minutes or so. I was really surprised because the Watson 970s lasted way longer than the official Sony 970.

For a full 13 hour shoot (maybe 10 hours of actual set time) I was able to use under two Sony 970s to power the FS700 and I used two Watson 970s and one Sony 770 for the 7Q. I feel like I could have only use the two Watsons for the entire shoot though since the batteries were around 7v to 7.1v when I pulled them and still had more life to it.

Definitely seems like the 7Q drains batteries faster than the FS700.

Anyways, I was always under the impression that the Sony L-Series were the gold standards, but the Watsons seems to last longer which was a big surprise.
 
I don't know about the Watson batteries, but the Odyssey7Q definitely draws more power in 4K than in 2K given the same frame rates. As the frame rate increases so doe sthe data load, so therefore the power drain.

You can easily monitor this yourself if you care to. Just below the battery voltage indicator is the wattage indicator showing how much power the Odyssey7Q is drawing at that moment. Clock on up to 2K/240p and watch the numbers rise!

Gene, are you still having success using these Watson batteries? i had all the issues described here today. I already ordered 3 original Sony npf's, but i'm still looking for options...
 
i just received odyssey original battery plate yesterday and it give me same problem when battery goes low. Haiz no idea it is really the battery problem or 7q problem. Luckily covert 2 sony battery to v-mount via tilta is working perfectly.

I've been having very good luck with the Watsons. They defiantly last considerably longer than the Sony 970 bricks, or at least the two that I have.
