Hey guys I been trying to find a place where I can buy cheap "working" batteries for the Sony FS100... particularly the NP-F970 batteries.

Since B&H photo is expensive as hell, I went to ebay and I saw a bunch of cheap generic and OEM(from china) batteries, but after reading several threads I found that there are a lot of fake battery manufacturers out there, soooo....

Has anyone bought batteries that actually work? if so, could you guys post the a link or maybe the name of the manufacturer?

Thanks

This one : http://cgi.ebay.de/ws/eBayISAPI.dll?ViewItem&item=150607205529&ssPageName=STRK:MEWNX:IT

and that: http://cgi.ebay.de/ws/eBayISAPI.dll?ViewItem&item=290488748431&ssPageName=STRK:MEWNX:IT

both work great for me - one usually takes me trough a whole day of shooting.

But Im going the v-mount battery route now - one v-mount powers the whole rig - monitor, camera, light, recorder, transmitter, cigarette lighter.

Here is an adapter for the camera. You bolt the adapter on any v-mount and put the dummy battery in the camera. Done.
It also has an additional 12v tap.

I mean... As always with batteries, you have like three choices:

1) Buy original brand new batteries from the camera manufacturer - in this case, the Sony NP-F970

2) Buy a better & more expensive professional 3rd party battery - e.g. something from Anton Bauer + Sony F-series adapter

3) Buy cheap chinese knock-offs from eBay. They are maybe not as good as real Sony F-series batteries, but they cost 1/3 of the price or even less, and multiple chinese knock-offs will surely give you more power & a longer life time than just 1 original Sony (for the same price).

$19.59, free shipping, for one 6,800 mAh NP-F970 knock-off.

Compare to $129 + tax for a brand new Sony NP-F970, 6,600 mAh, from B&H. With tax it's $140.60

140.61/19.59 ≈ 7.2


You get a bit more than 7 knock-off batteries for the same price as 1 Sony. Even if the Sony last longer (say the typical 1000 charging cycles) than a knock-off (say 500 charging cycles, just to exaggerate, it's probably more), when you add upp 7 knock-offs together...for the same price... I think the knock-offs will always win.

If we stick to the example above you would get a total of 3000-4000 charging cycles and a total of almost 50,000 mAh for the 7.2 knock-offs, versus 1,000 cycles and 6,800 mAh from the single Sony. Same price.

How knock-off are those knock-offs anyway? I mean, Sony doesn't make their own batteries - they also have them made somewhere in China - probably in the same factory.
Maybe Sony takes care of the specs - maybe Sony only have their sticker applied, who knows?

The two cheap batteries I have work exactly the same way my Sony battery does - also same specs and is recognized by the FS100.
One even has a power tap - something Sony doesn't provide at any price.

Yepp. They are probably made in the same factory, or something ironic like that. There is probably no big difference. Just making a point of how much bang-for-the-buck you get with knock-off batteries.

you do get the benefit of accurate battery level readings from Genuine Sony batteries
real Sony batteries are made in Japan

after seeing some youtube videos of fake/cheap Sony batteries being disected and shown inside out, I was a bit disgusted at the quality of those knockoffs under that plastic shell

It's like always. If the budget is tight you can get a lot of bang-for-the-buck with knock-offs. Basically the same shit more or less, but you get 7 for the price of 1. Minor trade-offs like battery level readings, less battery cycles etc.

But if you have the money go pro all the way. Get Anton Bauers or something.

Mandrean,

Have you tried these batteries before?

I've been using chinese knock-off batteries for years in all kinds of cameras and equipment, yes. Especially Sony F-series (NP-F970/NP-F770/NP-F550) and Canon DSLR-batteries (BP-511A/LP-E8). My impression is that they last for about the same amount of minutes but "die" quicker (i.e. shorter lifetime/last fewer charging cycles), though that statement is non-scientifical. Just pure feeling. Maybe placebo.

However, since they are cheaper, in the long run I feel it's more worth to get them when you're on a tight budget than original ones. Like in my theoretical experiment above.

Hey Frank it seems like those batteries are not sold in the U.S. :S

I notice they last like this in the beginning, but they do drop off very quickly. After about 3 months it seemed they lasted half as long on many knockoffs.

After about 3 months it seemed they lasted half as long on many knockoffs.I have not noticed that extreme difference in battery time. But even if it exists, for a lot of people knock-offs would still be more worth the money since you get the 7:1 ratio compared to original batteries. You just have to change them more often, but for the same money spent you get more hours in total.

For me, I like to buy big long batteries so I can run a whole day off of 2 of them. The 970s do that and I bought the dual charger from Sony. I hate having to charge 4 or 5 batteries the night before a big shoot because I have to remember to switch them. With this setup, I don't. Although I am thinking of doing a dtap solution.

The only knock-off batteries I've ever had success with are the Maximal Power brand on Amazon.com. I have used their Canon LP-E6 batteries and now a Sony NP-F970 (?) style and have had no issues. They run actually a tad longer than the official batteries and report their battery level correctly.

FWIW the same brand's LP-E5 (T2i style) batteries sucked. They cut off early. But the Sony NP-F and Canon LP-E6 style have been great! And 1/2 to 1/4 the price.

Okay, this here is one of the coolest things I ever saw.
It instantly solves all my battery needs.

A V-mount plate with build in step down converters:
2 x 12V outlet, 7,2 volt outlet, 5V outlet,
build in HDMI splitter, 5Volt USB, 4 spiral wires, and a build in charger.

Comes with 4 spiral cables.

Everything on a 15mm railmount, for- lo and behold: 163 Euros (about $230)

I made an extra thread for it.
