NEEWER4-Pack 7.4V 6600mAh NP-F970 Replacement Batteries with 4-Channel Battery Charger & Power Adapter, Compatible with NP-F550/750/770/970 FM500H QM71D QM91D, Field Monitor, Video Light

Wonderful product.! It took a Kastar charger hours to charge my np-f980's from 1/4 to 1/2 discharge (4 hours or more).This neewer has the job done inside of an hour!! Very nice product, it's very consistent, fast and doesn't cook my battery's. Note: I only use NP-F980's

Update: received a message from the Newer team! They were kind enough to give me a partial refund to buy a replacement battery. Customer service was great and I'll continue to purchase Neewer products!Unfortunately after a single use, one of the batteries does not work and is a dud. Outside of any support window too which is unfortunate. Other batteries are fine, but buyer beware.

I got these to use with the NEEWER Bi Color 660 LED Video Light, and they worked great! I liked how they were easy to insert and remove and keep track of charging progress with the LCDs. And, they are charged at the same time! They quit charging when full, and were not hot. They lasted a couple of hours on my first shoot, and was pretty happy.They aren't as bright as they could be, but you have options on brightness, and on having just white or yellow, or both. I checked other options, and didn't want to go too gebneric, and the NEEWERs were just right.

Works great and makes it easy to use my lights for my tabletop photography without having to worry about wires. The batteries last for hours upon hours before needing a recharge. I have taken 1000's of photos before needing to recharge the batteries. It makes it very convenient with the batteries over using the power packs and wires that come with the lights. These was definitely a good investment. When the batteries do need charging they charge very quickly and it is easy to mount and unmount from the charger.

I bought these to go with the NEEWER MS150B 130W Bi Color LED lights I purchased. My only gripe is that I wish Neewer included these with the lights. After all they do provide you the V-Mount to hold them for the lights! They are pricey but so far have worked out great. Much easier than dragging around extension chords everywhere and worrying about tripping over them. With my lights on full power these batteries last about 2.5 hours. I've used a couple of them as key lights at 75-80% power and they were still going after 3 hours. I would give a 5 star but price point isn't great, they don't include them with the lights and there is no case to carry them around in. They are fairly decent sized batteries and carrying around several of them can be cumbersome. Would love it if they sent them with a hard case storage. Work great, easy to swap out, super easy and a time saver with the lights and not having to drag chords around. I would recommend.

Neewer 4 channel NP-F970 took 5 hours to fully charge all my batteries. A much better choice over the PowerExtra 4 channel NP-F970 took8+ hours. I need speed charge during production.Clear WINNER

I love this 4 battery charger. Great when you need fresh batteries often. These larger sized batteries last significantly longer as well.

The media could not be loaded. I’ve always had the smaller ones but these are heavy duty, will last long, they fit in nicely with the charger and it came so well packaged that I keep them in the original box when not in use. They’re pretty heavy but still very portable for shoots without worrying about tripping on cables so definitely worth the price for how useful they’ve become.
