Powerextra 4 Pack Batteries and 4-Channel Charger for Sony NP-F970, NP-F960, NP-F950, NP-F930, NP-F770, NP-F750, NP-F570, NP-F550

This is a great set up. The display instantly shows battery level and charges everything equally and quickly!

Perfect product for my Video Transmitter needs during the conference last week. I was able to keep the batteries charged and ready.

The media could not be loaded. I picked these up for doing some shoots and interviews in places where power can be an issue. The charger does take awhile but I got about 3 consecutive hours out of the lights at full brightness with full batteries (I didnt try it with the wifi color control of the lights). Bang for the buck they are great and they fit perfectly in the GVM lights and the motorized camera slide. I will order a second one of these for my other 2 lights

Very affordable set. The batteries work great and the charger is very nice. Love the charging status display.

This had to be the best investments I made for my lighting kit. Charge speed is great and I love that it makes traveling with my lighting kit so much easier.

It's possible I have received defective batteries. They last only 10 minutes in my field monitor. I have used other brands with the same specs that last up to 2 hours. The company responded very quickly and sent replacement. I haven't tried them as yet but for the moment I am pleased with their service and support!

I needed extra batteries to power camera's, lights and a field monitor. I purchased quite a few thinking the equipment would chew up power pretty fast. I was wrong. These batteries are perfect for field work. They last a very long time, hold their charge and are fairly quick to charge. Because of these batteries I have no worries about how long I am out shooting of a day as these babies will last and last, Definitely a recommended buy,

Aprox. 4 horas en llevar las 4 baterías al 100%, al principio puede ser difícil insertar las baterías ya que no se siente como un producto muy sólido y los pines de carga se siente como que se van a quebrar o torcer, pero después del primer uso ya quedan alineados.Asegurate de tener una superficie plana pues las baterías no quedan trabadas y se pueden desconectar fácilmente, en especial por el peso de las misma.El cable incluido podría ser más largo pero es un cable común de 2 pines que puedes reemplazar fácilmente o usar uno que tengas.En general las baterías son excelentes, he logrado 8 horas de iluminación en los paneles LED al 15% de potencia.
