DSTE® 2X Replacement Li-ion NP-F970 NP-F950 Battery Compatible Sony DCM-M1 MVC-CD1000 HDR-FX1 DCR-VX2100E DSR-PD190P NEX-FS700RH HXR-NX3 Camera as NP-F930 NP-F950 NP-F960

I've been using these to power Atomos video recorders, and they work great. These are by a mile the longest-lasting NP-F970 style batteries I've had, though they are a bit bulky. No problems using them with my third-party chargers and stuff; they fit in and work just fine!UPDATE: After two years, the original batteries are still going strong. I just bought another pair. The only "problem" I've had is sometimes my battery charger (made by Watson, a two-bay charger) charges one of these batteries to 100% and then the display changes to 0%. If I remove the battery and plug it back in, the charger confirms 100% again (and the actual recorder I use also confirms 100% on the charge). Not sure if that's the charger or the battery, but in any case, they hold up well in the field and work great.

The media could not be loaded. For almost a year now I have used a portable video light by Powerextra. I works well, but I realize how fast the double AA batteries run out during long recording sessions. These batteries were the perfect solution to this problem and so far they help me get through long livestreams were I have to use my video light for almost an hour and they have performed really well so far.The batteries arrived fast and I was able to installed them almost right away to see how well they work. To my surprise the video light was even more intense with brightness using these batteries.They came with at charge of 75% and I charged them for about an hour to get them to 100. I have posted a video here to demonstrate how to install them to a video light. Let me know if this is useful to you or if you use these for other things besides video recording?I will add an update here in a few months to let you know how they are working out.

I've been testing these on a wireless camera monitor and light panel. The life is pretty decent, nothing to write home about. But for the price it was a good investment. Depending on the situation if using them with the monitor or lights all day 2 won't be enough. I get about 3-4 hours out of each. I've only had them for about 2 months so I don't have a comment on the longevity of the batteries. To early to tell if they'll hold a charge long term. I'd say if you're an avid film maker get 4 or 6 batteries if you need to rely on them.

Decent batteryWorks fine with atomos ninja V

Does great on my Atomos Ninja V External Recorder. One full charge gets me 2-3 hours of power. The only downside is the charge speed. They take 7-8 hours to charge on a multi-charger, so you need to have enough sets to create a rotation if they’re in your kit daily.

These things are lifesavers! If I could buy 100 and keep them on set all the time I would, they last so long! They definitely don't charge quickly though, so don't get the idea in your head that you're gonna charge them over lunch or you're gonna charge them in the morning for a nighttime shoot. You WILL need to charge them overnight and then some, especially if they have no charge remaining.Seriously, you can't overestimate the charge time. It's 100% worth it, but you will NOT charge these and shoot with them same-day.

I’ve had other NPF batteries that claim to be close to 8000mah but they barely last longer than a 2000mah battery. Not these. These batteries are the real deal. You can tell when you pick them up. They have a good deal of mass which means that plastic housing is almost filled with battery. I’ve had other batteries of the same size and they are only filled a third of the way with battery and their mass reflects their lack of capacity. These are best bang for buck and I would have actually paid more for them.

I have been using this for 2 weeks and the batteries lasts a very long time and while I'm not sure if it's truly 7900mah @7.2v it certainly does feel like it lasts that long since I've only need to charged it once for 4 of more video shoots which were for music videos and restaurant commercials. I think these are fantastic for LED panels especially those who do interview shoots and weddings. I do think it's on the bigger side but hey more power!
