Battery Life and Pocket Cinema Camera

PostMon Aug 26, 2013 5:53 pm

MrCheesyCam: ... If you just left the camera on without recording, I don't know if you'll even get 20 minutes out of a single battery. (
)

BMD: <see picture>

So any suggestion for battery pack?

UPDATE: BMD says 50 min. (https://vimeo.com/72972171#t=406)

Does he say what kind of batteries he's using?

With Original Nikon 1000mAH batteries, I witnessed Hot Rod Camera's single Pocket Camera hit a solid 30 minutes of straight recording on a 60 percent charge. I imagine that would equate to at least 45 minutes of recording on a full charge, and much longer standby times.

Without sounding too "I told you so" about this, if people are buying cheap knock-off batteries then they should expect cheap-knock off battery life. This isn't anything new or profound: professional photographers buy OEM, Manufacturer hardware for this very reason.

I hadn't posted this information yet (saw this last friday) because I'm waiting to do my own tests, but I'm pretty sure it's down to how cheap you want to be with your battery solutions.

Edit here: and, in most of these reviews, I'm seeing cheap knock-off batteries pictured. So many things can be handled before there's an issue if people stop trying to cut unnecessary corners.

I'd be curious to know, because that battery also had about 50 minutes of life in it from what I could tell, from a full charge.

Was told that the charging of the battery that comes with the camera could be confusing, because it seems like it's at 100 percent very quickly but turns out it's not a full charge. You pretty much have to leave it charging for about two hours or so for a full charge?

I've already plotted a battery solution for the camera out... just waiting on one to play with on my own to make sure it works.

Yeah, that's the one you get with the camera.

I saw way more than 20 minutes of usage out of the original battery on a full charge. Was definitely in the 50-60 minute range, camera on and rolling on and off.

Ok, but "blooming" remain :lol:

Also, that's the Nikon battery I'm referring to. That one is pretty stout, affordable, and has its own charger. Is that the battery Cheesy Cam used or is that the on you bought, Raadgie?

I think Hot Rod said they were going to sell them for 25.00 and the charger might be like 35.00.

Already bought, like many stuff for BMPCC. Only Camera is missing.

Idk about which battery Cheesy Cam is referring. I meant about in box one.

Some people are finding an 1800mAh compatible battery on eBay. I have no idea how reliable they are but if they are, that would help battery life.

I see NewEgg has EL-EN20 1800mAh battery.

Real, fake, or a really good fake ?

http://www.ebay.com/itm/271199483273

Nikon ENEL20 and charger for $27 ? I'm in. That's less than Amazon for just a charger and you can't have enough of those unless you rig it out and that defeats the whole pocket cam thing.

My rule of thumb is to buy from reputable dealers. Saving a few dollars isn't worth hardware dying quickly, or something weird happening. That's just me!

I'll let someone else try it first, for an extended period of time.

Heard this horror story about a cheap battery exploding on an Alexa and burning half the camera.

This isn't new, though, because those old DVX/HVX knock-off batteries that people got would explode as well.

Imagine that happening inside of the Pocket Camera.

Kholi, I've got cheap eBay knockoffs and they last as long as the BMD ones. I've also got knockoff batteries for my 7D, and only fault I've got is after 2 years they don't hold charge like the genuine one does, but when new they were perfect.

But those chipped batteries, like the Sony NPs, if you get fakes they don't work at all!

Craig, I recall reading a post recently about 1800 mA batteries that didn't last long at all. Can't say if the short duration was the fault of the operator or the battery. Let us know.

Look at the O in the word Nikon, and there are other signs.

The counterfeiters have gotten smarter trying to pass fakes with the holograms but you can tell fake stikers from the real Nikon ones. The battery charger is fake also.

I just checked the photos on the site I got the battery from, the photos are,of a,"real" Nikon battery, based the the example from,the Nikon site. I Will check the actual,battery when it arrives. If it is a fake, back it goes, wit a full refund for shipping an item that does Not match the published description.

I,will let you know how,this pans out.

Meanwhile, I,found a "real" Nikon charger used from a US seller.

Great, Denny. Most people may not take the trouble to do that follow up.

Call me paranoid but I usually suspect very good deals as "too good to be true" and feel they may be illegal copies or, worse if the items are actually genuine, stolen goods. I know so many people feel comfortable buying from the trunk of a stranger's car in parking lots and sites like EBay but I never have. For sole operators and a legitimate company without a brick and mortar storefront, I understand webstores can be a fantastic window to a worldwide market, but the occasional rotten apple spoils the barrel.

I agree Rick.

When using eBay, always check out the seller, to see if they are legit. I am also wary of "knock offs" ESP. Coming from China, and very rarely buy from China sellers, I try to keep my $ in the US, not overseas. But once in a while, you have to buy international, ck seller past performance and feedback is one indicator. If a "company" Goggle the company name see if they are the same.

I have also had good luck buying from fellow photographers/videographers upgrading and selling their older gear.

Be wary of unofficial batteries. Mine were all fine until one exploded in a charger, not using knock-offs again.

Bought 2 of these: http://www.amazon.com/gp/product/B00CMIU6OS/ref=oh_details_o04_s00_i00?ie=UTF8&psc=1

Both last approx 20 min max, and when i try to take them out of the cam, I need to use a key to leverage it out just far enough to grab it with pliers and remove it the rest of the way. The dimensions are off ever so slightly from regular EN-EL20 batteries, so the spring release on the cam doesn't work for these.

I knew when I bought them that they were nothing more than a stop gap to provide me with some power while charging the battery that was included with the Cam. However, I don't see myself using either of the 2 I bought ever again.

Thanks for those hints, especially to verify the company exists outside of their presence on a sales website.

So... about the same as a BMPCC then?

People, me included, thought battery life was rubbish to start with, but then it ended up that it's actually the battery meters that are rubbish, the batteries themselves last the 50 mins or so.

Got the "Nikon" battery and charger, they turned out to be original Nikon, but are "B" stock, the original battery/charger packed with the Nikon J1 when it came out two years ago. Battery is holding a charge and works OK.

I plan to solder that to an ikan battery plate

Maybe we try to put this in perspective.

I shot a short film on the BMPC last week.
We shot two whole nights and I turned it of between takes.
I needed 2 batteries per night - not too shabby in my book.
On an Epic I would have needed something like 8 RedVolt Batteries for the same time.
We had the original and a cheapo noname from Ebay, didn't see any difference, how long they last.
On the last day, I run out of my second battery in the morning hours, so we just plugged in a v-mount brick for the last two shots.

it's not the battery or the camera it's the cameras built in charger that's issue. i bought an external charger, cheep, and the charge time was a lot longer but it lasted a lot longer and i mean a lot longer. the built-in charger is junk in most of these cameras and BM knows it.

I did a shootout and the included battery gives me almost exactly 60 minutes with screen brightness 100% and focus peaking on. And 5 hours with a cheap external together with a third party nl-el20.
Shooting for fun.
