Swit S-8U63 Batteries with Sony PXW-FS5 and PMW-300

I recently decided to get two non-Sony BP-U style batteries as some of the six Sony BP-U60 ones I currently have are now almost 9 years old! I also have a couple of the BP-U30s that came with both cams. Whilst my oldest batteries still hold a reasonably good charge they are, unsurprisingly, not as long lasting as they once were. I can still get about 2 hours out of some of the older ones on my FS5, less on the PMW-300 though. The newest batteries I have give about 3 hours or more on the FS5 (which is terrific).

I was reluctant to buy non-Sony batteries as it's always good to see a remaining level icon in the camera's display. Also, every now and again one reads of a new Sony camera firmware update that breaks the "handshake" with non-Sony batteries. However, finding Swit S-8U63 BPU batteries at just £112 ex VAT (each - from Digibroadcast), plus the fact that they have both D-tap and USB outlets was just too good to pass on - so last month I bought two.

I'm happy to report they currently work well on my Sony PXW-FS5 and PMW-300 cameras. They are very slightly larger (deeper) than the Sony BP-U60's, the extra depth is where the outlet sockets are. They are also ever so slightly larger capacity than the Sony's.

When I update the firmware of the FS5 this summer - to get the recently announced free HDR capability (new Picture Profile number 10 setting), plus I might also buy the 120fps continuous 1080p HFR unlock key (depending on it's price) it'll be interesting to see if these new Swits will continue to display battery level information etc. But so far, so good!
