Kastar BP-A100 Battery 1-Pack Replacement for Canon BP-A Series BP-A30 BP-A60 BP-A65 BP-A68 BP-A90 US 0870C002 Battery, CG-A10 CG-A20 Charger, Canon XF605 4K UHD, XF705 4K UHD Cinema Camcorder

Got this to use with me C70 and so far I’m impressed. Powers the cam and a monitor via dtap just fine on an initial test. I’m also impressed that it comes with 2 dtap ports, though I’d be wary of going nuts with trying to power a lot of things at once, as every battery has its limits. The battery time remaining indicator works on the camera with the battery, which is a good sign, however it was definitely counting down faster than the original time indicated while the monitor was on (not surprising). Initial power up estimated 246 minutes of life. Of course the proof will be in a full day shoot field test and if the battery indicator remains accurate without suddenly shutting off as some of these 3rd party batteries are wont to do. I’ll try to update after I’ve been able to put it through a full day. Then of course it’s the longevity question. But for half the price of OEM and nearly 1/3 of the price of a Core SWX nano with dtap/usb, it’s hard to resist. Fingers crossed it holds up at least decently.

I'm so happy I picked this battery up and I dont even have a camera that uses it. The reason for my interest in this battery is that it has a very high capacity, 2 D-tap ports and a USB and is less than $100. I will be primarily using this to power my LED COB lights. In my testing, I ran a spotlight for about an hour and the battery didnt even drop down one indicator light. I expect this will power a 65w LED for a few hours, or most of the day, if I turn it off between takes. What's especially remarkable is that a large high end NY camera store is selling a similar, but generic version of this battery for 2 1/2x the price of this one. Im a Kastar fan, and have had good luck with all my purchases so far, and I expect this will be another great product. Pro tip, buy a vmount from Amazon and epoxy it to the side to make a handy universal battery which will latch onto your lights.
