Neewer Rechargeable Li-ion Battery Replacement for Sony NP-F550/570 Compatible with Field Monitor, Neewer CN-160 CN-126 CN-216 LED Light and Others

Excellent batteries because they fit in my studio lights and Blackmagic Video Assist.

These batteries are very versatile if you do any photography or videography. I'm happy with the charge that they hold, and the price was excellent.

My use is a Futaba R/C Transmitter that happens to use these batteries more commonly used in camcorders (also pretty old now that I think about it). The past battery was another no-name brand and it was getting pretty tired after a day's model flying. Today I made 3 flights with this new one and the monitor still showed 100% charge which is a big improvement over the previous one.

Good Product at a reasonable price.

I have had my monitor and the battery it came with for over 4 years. It still works as good as the day I bought it. I recently had an all-day shoot booked and knew one battery would not last the entire shoot. I needed to have a second one and picked this up. I put it on charge the night before and went to my shoot the next day. As expected, my original battery which lasts about 3 hours ran out of juice and I grabbed the new one, put it on my monitor and kept on shooting. It paid for itself on that first shoot.

I admit that Neewer is kind of that shadowy Chinese brand that you're not sure about in terms of quality. But I've bought a bunch of these, and even after six charge cycles, they're consistently delivering on the capacity that the label says they have. Full charges on my various devices (LCD monitors, LED lights) are giving about the life I expect relative to other batteries that I have.

Another neewer product that has been nothing short of a great experience. The batteries work and hold a charge as well as any other so far.

I'm a YouTuber and I use these batteries for my camera monitor and they work great! I've had them for a few months now and they work just as well as the original battery that came with my monitor. I would definitely recommend this product to others!
