NP-F750 Battery 2 Pack 5600 mAh Li-ion Replacement with Battery Charger for Sony NP-F550 NP-F570 NP-F750 NP-F770 NP-F930 NP-F950 NP-FM55H NP-FM500H NP-QM71 NP-QM91 NP-QM71D Camera

I bought these batteries to power LED lights made by Ivisii. One of the best features of LED lights is that they can run on batteries, so you can use them anywhere. The lights take the NP-F750 battery type, which can be pricey. When I found that Ivisii also sells a two pack of these batteries plus a charger for about $39, I had to try it. I put them into one of my LED panel lights and set the output at 75 percent. The light ran continuously for a full two hours, which is the same length of time my much more expensive batteries lasted. The charger also works perfectly. It is very light and small, but does a great job. It has two light indicators that turn from red to green when a battery is fully charged. The charger is so light, you can bring a couple of then with you. It uses USB power to charge, so just remember the charge time takes a while. All in all, these are great batteries with at reliable charger at a wonderfully affordable price.

A while ago I purchased an IVISII CY-IR60 Ring Light after a friend who is a professional photographer recommended it, and I can’t begin to express just how much I love shooting with that light. One of the features of the CY-IR60 light is the ability of powering it via two battery slots on the back which led me to my purchase of these batteries. As with the IVISII Ring Light this Lithium Ion battery set is absolutely top of the line. The set comes complete with the charger, two NP-F750 Lithium Ion batteries with a whopping 5600mAh power capacity in each, a micro USB charging cable and the manual. These batteries are such a great addition to the ring light! Due to the ring light utilizing LED lights the power consumption is low and these batteries being 5600mAh provide plenty of power to run them for extended shooting sessions without any problem. Being able to not worry about requiring a power plug for my light has allowed me much greater versatility in shooting locations while still being able to perfectly control the light on my subject. The charger is as excellent as the batteries. I have been able to charge the batteries via my car’s USB without any issue in between shoots just to make sure I always had plenty of power. When you slide the battery into the slot the LED light corresponding to that slot glows red until the charging cycle is complete, when it will change to green. The initial charging session took approximately 4 hours due to the enormous capacity of these batteries. Regardless of what you power with these batteries they are guaranteed to impress you with their capacity and performance. I love everything about these powerhouse IVISII batteries and the rest of this set - I can not recommend them enough.

I bought these to power my ring light and they're fantastic! These batteries lasted for just over 3 hours together on a single charge when powering my ring light. I love the portable USB powered design of the charger and that it can charge two batteries at once. There are two LEDs to indicate which battery is charged and ready. A micro USB cord was included but no power brick- which is fine because I have plenty of wall warts for my phone and have even used my computer's USB hub to charge them.

I'm so glad that they came out with a larger more powerful version of this battery. The ones I've been using are half this size, and of course last half of the time that these last. So I would have to change batteries during my recording every one to one and a half hours. This got to be a pain because I would have to remember to change the batteries every hour because I have had a battery died on me while I'm recording which is horrible. These new batteries are giving me 3 hours of continuous running. Also included is a dual charger which makes a lot easier and charging them on a single charger one at a time. So far these have been working great and I couldn't be happier with them. So if you're reading my review, then I recommend that you pull the trigger and buy these cuz they are definitely worth the money.

Great batteries. Fit perfectly, charge nicely. I like the independent LEDs letting me know the status. Only reason this is 4 stars is there isn't a charging brick. Other than missing the charging brick, perfect.

It took about 12 hours to charge, for the Ted charging station to turn green So don’t be alarmed. All good though it works, that’s the main thing. Using in my gvm studio lights

I used these on a transmitter from a camera to a switcher for a Jumbotron production at my local school. Usually about a 4-5 hour production. These batteries easily lasted the whole time, I never even got a low battery warning. I’d have to switch camera batteries mid production, but these lasted forever! Love them, would buy again.

I purchased these expecting them to be a quality product but was surprised at how quickly they go dead. I have only used them 5 or 6 times in a year and for starters they take literally all day to charge with the included dual-charger and then they go dead in minutes, but more concerning is that they do not hold a charge for more than a day or two. Very strange! Seems like all I do is charge these. Luckily the small LED lights I use also have a AA battery compartment...AA batts. last MUCH longer and actually hold their charge for nearly a month. I stopped using these batteries a few months ago but thought I'd give them another try and same thing. 8 hours to charge, used them for 5 minutes to photography one item for eBay and tried to use them again 2 days later but they were totally dead! NO CHARGE LEFT AT ALL! Save yourself the aggravation and get genuine SONY batteries!!! Shame on this company for selling such third-rate batteries!!!
