SONY Cameras : PXW-FS7

BP-U65 used in event shoot ...

I recently used one BP-U65 battery on a 4 hour event shoot just to see how it would perform. It performed very well … no hitches … no glitches … it just worked. I still had 2 hours listed on the battery monitor read-out on the Sony EX3 camera used in this shoot. So at this point I can say it has been battle tested!

BP-U65 Battery (OEM) with D-TAP/USB 2 for Sony PMW HD + PXW FS7 XD Cameras


I don't know if you are like me but when you own several cameras you surely buy a lot of different batteries. So, I was mulling over the new Sony PXW FS7 camera as my next upgrade which has a S35 CMOS sensor with 4K/2K and XAVC recording options … the perfect camera for a one-man-band camera operator.
I also have the Nano-Flash to record 422 HD from my Sony EX3 camera which has been a very stable camera for event and documentary work. I will be in need of a battery with D-TAP that can run both units on the EX3 and run similar on-camera recorder/monitor options for the FS7.

I went on the hunt in the Fall of 2014 to find a reliable and trustworthy battery manufacturer who makes on-camera monitor charge read-out batteries for Sony cameras that included a D-TAP connection. I found one in China and as most of you know, China makes most of the batteries for major brands on the market today. I have a lot of experience with off-brand batteries and have bought other batteries over the years from Chinese battery makers which did not last very long. In fact, Jared Land had batches of such types of batteries for the DVX 100 years back before he joined RED and I bought a number. They didn't last … typical problem unless you do some heavy lifting and get into who's battery 'slurry mix' really drives professional cameras for a good number of years. Chinese battery cells are frankly not very good … mind you that is changing but who wants to buy lemons to find a few good oranges.
I had to make a change … in my research on battery chemical 'slurry mix' you get to the heart of the matter. The chemical mixes and refinements are the key and every battery maker has their patented formula mixes, drying processes, hardening, cutting, rolling and encasing processes that give you their brand of battery. I had the manufacturer for my batteries get Samsung cells to go into the battery case because Samsung makes very good battery cells … as good as Sony!
Through the on-camera monitor the clocked time I tested on the EX3 was a stable 358 minutes and with the NanoFlash 340 minutes. The Sony FS7 clocked in at a stable 328 minutes … it draws 19 watts after all.
Well … to make a long story short I've finally received my batteries. If you need a battery that can run a camera and other devises on D-TAP or USB 2 you might want to pick up one of these BP-U65 batteries at
Amazon.jp while they last. Good for the following Sony cameras:
PXW-FS7, PMW-280, PMW-260, PMW-160, PMW-100, PMW-200 , PMW-F3, PMW-EX1, PMW-EX3,PMW-EX3R,PMW-F3K
