K&F Concept V Mount Battery 99Wh 6700mAh with PD100W USB-C Fast Charging, Mini V Lock Battery with D-TAP/USB-A/Dual USB-C/DC/TFT Display/Emergency Light for Camera, Camcorder, Monitor, Video Light

I needed a solution for continuous and reliable power for my outdoor live streaming rig. After relying on power banks and camera batteries for some time, I needed a stable alternative so that I didn’t have to keep a continuous watch on numerous batteries and briefly take the camera offline to change them over. The battery is a good weight so helps to add some weight and balance to the tripod once evenly distributed. I coupled this with a V mount clamp (purchased separately) which fits onto 15mm rails. The battery arrived with around 80% charge and wanting to put it to the test I didn’t charge it before its first use. After 3 streams and around 9-10 hours of use powering a Sony A7 iii via a dummy battery (purchased separately), the battery is down to 39%. It’s been out in overnight temperatures for a good 6 hours at around 1C to 2C and so far operated flawlessly. The included cable is the perfect length for my rig and perfect to uninterrupted fast charging. I chose this battery as it was slightly less expensive than other brands at the time of purchase but seemed to offer more in terms of available USB C & A ports which needed. The screen is small, not the sharpest but high resolution it’s really not needed. It’s a colour screen and only for checking available power, anything greater would just add to the battery drain so perfectly adequate for what and how long it’s used for. So far, I don’t have any issues and would recommend if your looking for a similar solution.

Really nice battery for my Z6III cinematography set up.

I bought this after seeing a friend have something similar - they had the popular Smallrig version, but I like the colour of this one (honestly, if something comes in funky colours, I'll buy it - whether I need it or not!)I used this the other day filming 4k video on a Sony FX30 for a solid 4hrs and it only went down by 20%, so it's worth it's weight in gold for long days of filming!It clicks nicely into a v-mount system, and has a perfect amount of sockets for my setup.It'd be nice to have 2 d-tap plugs, but it's not something I currently need.

Nothing much to add, it works and delivers as per the description. Feels really good built quality, so expect to have it in my arsenal few years.The only downside, not related to this specific product is it's tricky to find descent D-tap to USB-c adapter, also the 12v jack size should be provided so that one can buy the right adapter (most won't even work )

Super fast charging via USB-C 100w PD! Been using with a built up mirrorless body and a Ninja V recorder. Couldn’t be happier (as happy as you can be with a battery! ) can’t speak as to it’s longevity yet and I really don’t like the gloss finish on the back.

I use V-mounts for my job every day so wanted to make sure when buying new ones I had the best. I tested 5 of the most popular v-mounts and thought i’d share my opinion to save you the hassle of going through the same. A lot of it is just that, my opinion, so a different battery might suit you better.My choice: K&F Concept 99Wh PD65W versionRUN TIMES:First of all I tested run times on a high drain camera and monitor. They all lasted within 5% of each other. So it’s safe to say this is not a consideration when testing. I did wonder if the larger ones would last longer but they were almost exactly the same draw. Perhaps cells might last longer over time but hard to quantify this in testing.SIZES:They are not all the same size. If size is important then they are ordered from largest to smallest in my image attached. They may only vary by 10% but to me that feels significant when carrying multiple batteries and wanting to reduce bulk - especially when you aren’t really gaining anything for the extra size.WEIGHTS:K&F 100W : 650GNEEWER: 605GFX LION: 542GK&F 60W: 549GIDX: 553GPRICE:Clearly important - I always like a deal however these were mostly Black Friday deals so not sure on actual prices so make your own decision when purchasing.So to quickly run through the likes and dislikes of each (left to right in the image):K&F Concept V Mount Battery 99Wh 6700mAh with PD100W USB-C Fast ChargingLikes:- Well made, feels robust- D-Tap port easy to get out- 100W in/out as long as you have compatible charger- Light on the backDislikes:- Gloss screen - Easily scratched. Don’t understand this new solid black gloss look- Screen takes 2 seconds to ‘load’ when not powered. Shows logo first before anything else. Doesn’t sound a long time but others are instant- ON button is on the side, not the front like ALL others, so when on a multi-charger it’s not always accessible to check power status or even find the button as it’s also flush to the body- Top flap for USB’s is impossible to get off. Takes at least 5 attempts to get your finger under and peel out. Biggest dislike for me!- Only 1 D-tap…so why the bigger body and higher price? The 100W USB-C- Largest AND heaviestNEEWER Mini V Mount Battery 6800mAh 99Wh Likes:- Nice all black finish- Gloss screen looks nice (but WILL still get scratched) - better than K&F 100W though- All ports super easy to access. Flaps not stiff- Screen feels quite basicDislikes:- Only 1 D-tap- DC Output not useful for me and takes up space- USB-C port on the side which may get annoying, Prefer top option or one each side- 60W max USB-C- Heavy compared to belowSONGING FXLION Wireless Nano TwoLikes:- Only one with lights and screen. You get instant charge lights on button press with screen milliseconds afterwards. Very fast- Rubber port covers fit well but see dislike- Two top located d-taps- Wireless charging for your phone - don’t see this often- A good size - more blocky than the next two but a good compromise- Nice design imoDislikes:- Screen never stays on (biggest dislike)- Rubber ports are very hard to get back flat, if you are stacking these next to each other they will catch and rip the port covers or at least bend them. Bent rubber is impossible to get back flat- USB port take a while to get back in- 60W max USB-C- USB in Volts not WattsK&F Concept V Mount Battery 99Wh (6700mAh) Mini V-Mount Battery with PD 65W (MY PICK)Likes:- Great size. Feels the smallest- I love the plastic design with the triangle texture. Never keen on those gloss black plastic of nothing- Screen stays on when in use- Screen is tilted up not flat which i prefer when on a camera or monitor- No DC ports (which i never use so happy to save the space)- Has a minute counter which is pretty unique. Shows either minutes until drained at current power or minutes till charged. Pretty accurate too so impressed with this for the price.- Screen shows everything on one page - Minutes remaining, Battery icon bar, Percentage charge, USB Voltages and Battery Voltage- Cheapest of them all - got the best deal. Under £100 ex VAT.- Feels well made, grips on both sides- Ports are REALLY easy to get off and put back on. Harder plastic and makes a big difference.- D-Tap on both sides which is a bonus considering the priceCons:- 60W USB-C in/out but rarely do I need 100W- USB-C shows Volts not Watts- Heard that K&F can be a ‘cheaper’ Chinese brand however so far so good…aren’t they all made in China anyway?IDX IMICRO-98P Mini V-Mount BatteryLikes:- Smallest battery of them all but only by a tiny amount - maybe 2mm compared to K&F- Feels solid and good weight- Port flaps are plastic not rubber so will go back on better- Torch on back- IDX are reputable in the industry and I still own IDX batteries from 10 years ago. Paying for the name and testing I would assume.- 2 D-tap portsDislikes:- No USBs- D-Taps only on top- Port flaps quite hard to get off - need nails- No screen - only 5 lights for battery life- Pretty basic battery- More expensive than the others by far

Perfect customer service, and product highly recommended
