I bought 2 of these:
http://www.ebay.com/itm/150wh-V-lock...ht_2342wt_1352
-150wts (minimum I would recommend - our cameras are POWER-hungry!) = about 1hr 45min record time ea ( WITH a PIX recorder D-tapped to it too, so even better with just the SSD)
-LiIon = light weight
-cheapest I have found ANYWHERE
-Free shipping (from china!)
-Free chargers (nothing fancy - but they work fine - oh, and: FREE!)
-Paypal with ebay protection - no BS about Bank $ transfers like some "other" overseas Battery suppliers
-great before and after contact and support. Any Qs answered same day.
-displays Voltage in camera LED/EVF
-look/feel/appear to be identical quality to any other brick I have held
will be buying more...
Anton Bauers as above mentioned are a great battery, but, man, they are DAMNed expensive, and nothing I have read here in RedUser suggests they are any better. V-bricks rock.
Back:
I bought the x set-up. best turn-key system/price IMHO. Great service. Quality products.
