This Revolutionary Camera Battery will Lighten Your Bag and Change the Way You Shoot

For many photographers, power is a major struggle. If you're shooting video or working in live-view, a battery charge never seems to last, so you're stuck carrying 3 or 4 batteries in your kit. X-tra battery is here to solve that problem and simplify your kit with one revolutionary accessory.


Think it’s hard to get excited about a battery? For most gear heads, power solutions and batteries have generally been the least sexy accessories there are, until now. The X-tra battery solves multiple photography headaches and even offers some solutions you didn't know you needed but soon won't be able to live without.

The X-tra looks streamlined and well designed. The main portion of battery fits nicely into the camera's battery slot while the bottom piece extends out the bottom to provide an additional gripping surface.

For starters, in terms of power capacity, the X-tra holds 3,700 mAh, which is two times the charge of Canon’s LP-E6. Previously the only option for a double capacity battery was to use two separate batteries within a battery grip, so lots of photographers will potentially be able to eliminate an additional piece of bulky equipment. The X-tra is a full-size camera battery, similar in size to the battery found in the Canon 1DX. The physical profile of the X-tra extends just beyond the bottom of the battery compartment on compatible camera models, providing a solid grip for larger hands and a comfortable, extra secure feel. Because the X-tra requires the camera’s battery door to be removed, you can quickly change out batteries with one hand without fumbling with a battery compartment door. When it is time to swap batteries, it’s a super fast and easy process. Just press up on the battery to release it and replace it with a fresh one.
The X-tra pops into place snugly and easily and releases with a single press. It feels secure and allows an amazing fast, one-handed battery swap during shoots.

Unless you have a foolproof personal battery charging system (dead batteries in a certain compartment, or if the battery cap is on its charged, etc.), it’s easy to get charged batteries mixed up with dead batteries in your bag. Anyone who has ever replaced a dying battery with a dead one (it happens to me every so often), knows it’s a pain in the butt and grinds your shoot to a halt. The X-tra was designed with that common issue in mind and features a charge level indicator to help avoid dead battery headaches. Unlike other batteries that you have to load in the camera to test, the X-tra will show you just how much juice you have left quickly and easily. With the press and hold of a button, you’ll be able to see just how much charge the X-tra still has with up to four illuminated indicators, saving you time and irritation.


For the times when you need to have your camera in constant operation beyond the life of a single battery, no matter how big its capacity, you can plug the X-tra into another source of external power via USB-C connection. Planning on shooting a 12-hour time-lapse? The X-tra has you covered with direct charging, no battery swaps necessary. Whether you plug into a wall outlet, a car charger, or another larger battery, you have the flexibility to keep shooting for long periods of time.

That pass-through charging will come in handy for photographers shooting video, time-lapse, and any other applications that require long term, continuous camera use.

The X-tra utilizes the same technology as Tesla in its batteries, so the batteries are durable and stable in any environmental condition. X-tra also features ultra-low internal resistance to secure voltage stability and excellent performance for extended continuous shooting. Thanks to an integrated microchip, the X-tra keeps track of when the battery is fully charged and will prevent overcharging, extending the life of the battery.
Power your peripheral devices with ease. Just plug any accessories you want into the USB-C port on the X-tra and you'll be able to eliminate additional power sources from your kit.

Another cool feature is the option to plug peripheral gear and accessories into the X-tra battery even while it’s in use by your camera. Using a cold-shoe LED light that requires an external power source? Plug it into the X-tra via the USB-C port and you’ll be able to power both your camera and light simultaneously. This will be a great space saver for photographers and videographers alike. Whether you’re using a powered gimbal, a microphone, or other peripheral gear, you’ll be able to provide power seamlessly as you work.
The X-tra, seen here in the fast charging case, becomes an easy power bank for phones and other accessories, so you can carry at least one less charger in your bag.

The X-tra comes with a special fast-charging case which serves two purposes. First, it allows you to charge your X-tra battery surprisingly quickly via USB-C. Second, the X-tra battery can be used as a power bank for any device when mounted in the charging case, so you can even recharge your phone on the fly.


The X-tra is currently compatible with the following cameras by Canon, Sony, and Blackmagic with planned Nikon availability coming soon:


Canon: eos R, eos R5, eos R6, 5D IV, 5D III, 5D II, 5Ds R, 5Ds, 6D, 6D II, 7D, 7D II, 90D, 80D, 70D, 60D
Sony: α7 III, α7R III, α7R IV, α7S III, α6600

Nikon: z6, z6 II, z7, z7II, Z50, D500, D600, D610, D750, D780, D7000, D7100, D7200, D7500, D800, D800E, D810, D810A, D850, P520, P530, V1
Blackmagic Pocket Cinema Camera 4K/6KB

In designing the X-tra it seems like they thought of everything you could possibly want or need. Get ready to pack lighter, shoot longer, and enjoy a variety of conveniences thanks to a well designed, unparalleled piece of gear. 

What do you think of the X-tra? Can you see yourself upgrading your kit to include a couple of these batteries?

Please note there have been reports of issues involving this Kickstarter project, in particular reports of unreceived payments. Please carefully consider the risks of crowdfunding before you invest.

I'd want to test the ergonomics of this before deciding.

Alas this article is a bit light on the details - feels like a cut and paste of a press release.

How many recycles? (And perforce curve over age / use).
How fast is the recharge time?
How long do they hold charge?
Affected by cold?
What about transport by air - regulations?
Charging technology unique to this battery or would other batteries of similar type use same chargers?
How secure is the latching mechanism?
How durable against shock, dropping?
What about weather selling wit the door off and this battery inserted?
Costs?
Cost of charger?
Website for manufacturer?
Warranty of batteries?
Warranty implications for camera?
Same tech coming for regular size batteries? (For those who actually like having a grip)

Answer me these and I'll see if I'm interested.

Ah... just noticed... This is a sponsored post. Lack info and big-hype make more sense now... :)

It's F-Stoppers, so ....

Looks like this is an underfunded Kickstarter campaign: https://www.kickstarter.com/projects/x-tra/the-camera-battery-re-invente...

Thomas H's picture

Their kick-starter web page states that the Z50 is not supported (no EN-EL25 compatibility.) That differs from the list of supported cameras in this article.

Travis Saunders's picture

If you are refering to the A6600, that camera takes the Z100. I think the article is correct.

Michael Harris's picture

Reads almost word for word from the kickstarter campaign.

Usman Dawood's picture

The campaign quoted the article... a lot haha.

Tammie Lam's picture

An extra LP-E6NH is 80 grams. How heavy is this miracle battery? I bet it's like 120-140g, so saving like 20-40 grams and losing weather sealing in a $4k camera? No thank you ;)

Tom McCarey's picture

As mentioned above, this article is very light on pertinent details.

Michael Comeau's picture

Did you even use the batteries?

Jan Holler's picture

Hi Jordana, thanks for the article. Regarding "charged batteries mixed with dead batteries" I have a simple solution: Use small rubber bands that you wrap around each charged battery to distinguish the full ones from the dead ones. It is fool proof and works great.

Never Mind's picture

Nice tip, thanks.

N A's picture

Canon includes a yellow plastic cover with LP-E6(N). There is a little battery shaped cutout on the bottom of the cover which shows a bit of the battery label. Clip the cover on so the blue shows = charged battery. Flip it around to show the grey part of the label = dead battery.

Easy peasy lemon squeezy.

Trey Mortensen's picture

I always just did yellow cap on for charged and the two separated for empty. That also incentivized me to get the empty battery out of my bag to charge again.

Patrick Garrett's picture

Lithium batteries have a lot of power.. It is important to keep the terminals covered, so storing them without the yellow clip on is dangerous. My son threw an unprotected battery in his pocket with his car keys that shorted and almost burned his leg before he got the battery out.

Loren Pechtel's picture

Danger!! Even a "dead" lithium battery has power and they have very low internal resistance. Also, every camera battery I have ever seen has the contacts close together. Let a piece of metal touch those contacts and you risk a fire. Never transport a lithium battery without some sort of container--either it's cap or inside a device. The airline rule against uncontained lithium batteries exists for a very good reason!

Captain Jack R's picture

Great idea! I use little Red and Green cloth eyeglasses bags to keep my batteries in while they sit in my backpack. I hate having things making noise when I walk around. But I didn't have a solution for the batteries sitting on the gear tower. Thanks :)

Spike Hodge's picture

I have a similar system involving two pockets.

Matt Rennells's picture

From looking at the kickstarter, this appears to be a custom battery sized case to hold a couple of Panasonic vape batteries to power your camera with.

Spike Hodge's picture

"vape" makes it sound ugly but, yes you are correct, they are essentially the same lithium 18650 cells used in things like the Tesla Power Wall and NiteCore flash lights. And your Ross/Anchor power bank. Their use is a plus point not a negative.

Captain Jack R's picture

Yeah, they might be the Panasonic 18650s or some other generic brand of the 18650s. I doubt their quality as I use them in my flashlights and while they are powerful, they at random times go dead as a doornail. Very unreliable and I can't ever use something like that on a paid shoot. Now if they were using official Panasonics then I might be more interested.

Rick Rizza's picture

Umm, my R6 works just fine with power bank 10Ah where the price is amazingly cheaper than this shit and goes directly to the R6 USB C port without protruding things with bull shit feature as an extended grip. What's the point of this shit? Another useless kick starter gimmick for money?

Edit: I love it when I make a right call. Why is this scam articles still here??

Ben Goldenberg's picture

My canon m6 markii will not charge from a power bank, so some of us might have a use for this. The ones canon screwed that is.

Rick Rizza's picture

You will need a PD power bank (usb c to usb c). It only recharge when it's off but will slow drain your battery when it's on. Buy brands like Anker will give you a good charge. Or some other Chinese PD powerbank which works for me.

Tony Clark's picture

A single battery with charger will be $150, a little pricey for me even if they have twice the power of the OEM battery. I personally would not want the battery to extend past the grip but wish them luck. The kickstarter of $10K seems a bit strange, small change for starting a new endeavor like this.

Rick Rizza's picture

In the end they still use usb c cable in which eos R has a connector for it and power banks was available since ages ago.

Andrew Eaton's picture

Just a slight gripe, when quoting battery capacity, quote it in Watt Hours not Amp Hours... You cannot compare one battery Ah against another without stating the nominal voltage. Take 2 batteries that are 3000mAh one is 3.7v and the other is 7.4v.. one is 11.1Wh and the other is 22.2Wh and twice the capacity...

Spike Hodge's picture

Actually a serious and important gripe

Les Sucettes's picture

You can simply attach an external battery with USBC on a Fujifilm XT3...

Done ✅

Rick Rizza's picture

Also Confirmed with my eos R6 and cheap shit Chinese power bank with cheap shit usb c cable

Adriano Brigante's picture

Beware of any "revolutionary" product that needs a crowdfunding campaign to get launched. That screams scam to me. If the product is really that good, real investors will be more than happy to fund it.

Ben Goldenberg's picture

Peak design is an example of you being wrong. There are others.

Jan Holler's picture

I am disappointed by Peak Design. Bought a lot of stuff of them I now hardly ever use except for the straps. But even they began to loose their black rubber and spoiled some of my shirts. So I scratched it off.

Spike Hodge's picture

I love the Peak Design kit - just wish it was a bit cheaper.

Captain Jack R's picture

I too am disappointed by Peak Design. I have their clip on my backpack and it's so hard to slide my camera in and out. It's a real pain in the ass to work with. But they are the only ones that have such a device that isn't a cheap knockoff that breaks. I've been thinking about making a review video to demonstrate how bad their product is but I'm in search of a better solution to lead viewers too.

Loren Pechtel's picture

I've never had any problem sliding the camera into the clip on my backpack so long as I had the clip mounted in the right spot--mounted a little too high and the angle was always wrong.

I have quit using it but for a totally unrelated reason--I got more in shape and now I weigh a bit less--there's less padding over the bones there and where it rides the body is nothing like flat. Hours on the trail and where the bone is would become uncomfortable. I haven't figured out a work-around and now carry my camera in a Mystery Ranch chest bag instead--works, but I would prefer the clip if it didn't end up hurting. I still use the clip on my camera bag which doesn't get carried anything like the distances my hiking pack goes. I also generally have my Peak Design tripod in my pack--it's the only decent tripod I've seen that will go in a daypack.

(And, yes, I am aware they sell a "pad" for their clip--it is **not** a pad. It spreads the pressure but it has no padding and thus provides no benefit when placed over an uneven body part. Belt carry--good, shoulder strap carry, forget it.)

Andrew Morse's picture

I don't know, this puts up a lot of red flags in my mind. They don't seem to have a website or a history of other products they've successfully delivered to market, and if their gap in financing is only $10,000, it seems odd to go to a kickstarter for help. I mean, $10K is not a lot of money in the world of creating new products, so if the decision to go forward or not rests on finding $10K, then it doesn't seem like the company is willing to take a lot of risk in building the product. $10K doesn't seem like enough to engineer such a product to work with numerous brands, nor enough to test the product to be sure it works under all conditions without posing a fire hazard, or compromising weather sealing. What about the costs of registering electronics in the US or even in different countries? It's a cool idea, but I'd definitely be inclined to wait and see if it ever comes to market, and if it does, to let others test it before I put it in my camera.

Fritz Asuro's picture

I think Blindspot's new cables are more promising https://www.blindspotgear.com/power-pipe
Though given you have to buy dummy batteries and a power bank with PD to use the cables, but it's just more usable in my opinion.

dale clark's picture

So the current battery provider cannot replicate this? Nothing here........

Chris Rogers's picture

The camera system they REALLY need to make these for is the Fuji X system. Battery life on those cameras is total garbage. I can burn through 6-7 batteries on my Fuji Xt-1 or my XT-2 before I even empty one battery on my Nikon D800E. That's with all the power management I can muster. My Nikon D700 can shoot all day on 1.5 charges while being on. Yes I am well aware mirrorless uses more power for the EVF, Back screen, and various other functions which makes me wonder why companies have not made extended batteries like this as first party. Instead they make you pay $50+ for a single battery that MIGHT last you a couple of hours.

Aaaaand it's a kickstarter. no thanks.

Johan Doornenbal's picture

There is no way I would use one of these, even if they offered me money to use one.

Alex Ford's picture

As soon as one comes out for the D750, I'll buy one. Also, I would add that i'd love one for the Nikon Df, as well!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

andy wee's picture

I play and built my own batteries. I built my own enel15b , batts for my phaseone, batts for my friend's h6d and my 1.7kw powerbank. So i know my batteries. This battery doesnt make sense

1) enel15b and others of similar size usually use ncr18500 cells rated at 2000mah. Hence 7.4*2000mah

2) this is rating at 3700mah?? The biggest cell is 3600mah and thats not cheap.

3) cylinder cells are able to withstand ultra low temps better than polymer. Eg. 18650/21700 can do -20c no problem. The polymer bottoms out at -10c, meaning cant even power on.

4) there is no way he can fit a 21700 in there.

5) the usb port is gonna be a weather sealing problem. And dust too. Unless its those magnetic stuff.

6) charging via 5v/2a or 9v/2a? Or just 5v/1a? Cause charging creates heat. That small compartment aint gonna cut it unless its slow charge.

My enel15b are pushed by me from empty to full charge in 1h. And boy they are warm.
I like the concept of his batts. But alot of the workings of it just doesnt make sense.

Spike Hodge's picture

I'm surprised at the anti kickstarter vibes. I think it's a pretty cool system to get "small peoples" ideas off the ground. The good ones make it (e.g. Peak Design) the bad ones (maybe this project - up to you) don't.
You can't really get ripped off unless you accidentally invest in something you think is crap. It's all your choice.

Ruud van der Nat's picture

So an extension to your camera without any buttons (sounds like some Nikon battery grip ) I'll just double the capacity with a grip and have extra controls in portrait position. The external charging is handy though, but a lot of modern cameras offer that anyway.

Jared Ribic's picture

Make this for my EOS R5 vertical grips and I'll give it a try.

Alton Marsh's picture

I need to use an L bracket so that would have to be removed every time I changed batteries. Will my Canon R5 still report battery health with it?

Jason Siebels's picture

I find it very telling that they've chosen to compare the power on this to the LP-E6, a battery pack that's over 10 years old, instead of the newer LP-E6NH.
