[Lithium-Ion] Awesome, awesome batteries. I bought these 2 years ago anticipating run & gun scenarios where I would need to throw on more power on the fly without powering down, and sure enough those instances came up. The linking mechanism is a phenomenal design, allowing for quick power as stated above, but also for set-and-forget charging, allowing you to stack up to 8 in a single column. When my cells eventually wear out, you can bet the barn I'm going with PAG again.

[V-Mount] I've been using PAG batteries almost since they came out. They are the best batteries I've used in my 40 years and more as a Marine Wildlife cinematographer, and I've use many over the years. They give me a minimum of one hour plus top side use and as much or more in my Nuaticam underwater housing. The stacking ability is a real plus. They are also a lot less hassle in traveling as they are airline approved. The compact package they come in is a real plus, because they are lighter, smaller and easy to travel with.

[5 V, 3 A] I got two of them. I love all the different connections and the small screen that gives you the info. I use them to power my C500 MK2 as well as my Shinobi monitor.

[100 W] Where to start? This battery is both durable in it's construction as well as usability in that it can be stacked to add amperage to a battery powered source that requires more than a typical 94wh load, this is genius. The fact that it trickles discharge from the exterior batteries inward means you can hot swap peel away the end battery off your camera/light/whatever-you're-powering while leaving a charged battery on board and add a fully charged pag to the back. This means never having to power down as long as you have 3-4 of these babies charged up. Speaking of charging, they stack and trickle charge as well! 4 Pags per AB charging plate. This saves you space, money and time as well as weight with less chargers needed in your flight case. The exterior power gauge is helpful showing you a rough percentage of remaining battery in numeric form rather than some of the other cyptic icon systems (speaking to everyone, looking at Anton Bauer). I can't speak to the life time of the battery, but it's been plugging away giving ample charge and discharge cycles for the better part of a year with no noticeable memory loss. Do yourself a favor and stop buying cheap batteries and get some PAGs. It'll be hard to go back to non-stackable battery systems after you have a chance to work with these PAGs...

[65 W] I currently own five of the PAG PL150 Series 150Wh and six of the PAG HC-PL94T.  Im so glad I invested the extra money for these batteries.  Theyre just so incredibly versatile.  Love the fact they stack so I dont need to wake up in the middle of the night to swap out batteries as they charge.  Also, when they stack they become much more capable batteries if you need more Wh or A for lights, etc.  Expensive, yes, but I believe worth it in the long run.

[65 W] I love these batteries. The linking technology is amazing. First day I used them I needed to do a shot where the light was on for a long time. Linking two of these together kept my light on and I didn't have to do another take once one battery died. The fact that these work with my Anton Bauer chargers is also really helpful. I didn't want to buy another charger. Each battery is also really well made and designed. You can feel safe you're not going to drop it due to the material on the outside. After using these batteries you will not want to use any other battery again.

[14.4 VDC] Hats off to PAG .... Brilliant small batteries ..... Linking .... the most brilliant implementation i've ever seen

[Lithium-Ion] I bought 4 Paglink HC-PL94T batteries. One of them stoped working and I returned to PAG company. They replaced 4 new batteries for me. I really appreciate it. Highly recommended!

[Lithium-Ion] I love this battery!! You can piggy back multiple of them and you can take this on an airplane. I recommend you get a couple and try them out!
