Bmpcc batteries in uk

Where are people getting there spare batteries from for the bmpcc? I bought around 8 from different eBay sellers over the past few months and they are all junk.. Last about 20 mins then just turn off at around 30%.

What are classed as the official battery for the pocket?, is it just a genuine nikon en-el20?

Problem is these are £35 for one!!..

There are some expro ones on amazon for £8.. Anyone have experience with these?

I bought the Blackmagic branded batteries from B&H.
Got them in like 3 days, not the 7 to 14 they have listed.

I'm using these and they seem fine:

Have 4 of them and the run about the same time as the one that shipped with the cam.

How about an external battery? It has 9A of power. It may give 7-8 hours of recording, based on BM battery's capacity calculation.

Just placed an order with jigsaw24 for a couple of Black Magic original spare BMPCC batteries (£15each), seems very reasonable cost for peace of mind.

Thanks for that!.. Tweeted both thenm and CVP about these this morning! I had no reply from jigsaw and CVP said they didn't exist until I sent them the b&h link!
