Kastar 2-Pack BP-A100 Replacement Battery

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.

Over all I would say this was a great battery for Canon BP-A cameras, however it cracked upon insertion on a studio shoot. Camera was static. I wasn't happy about the battery and very worried that it could have damaged the camera too. We immediately took it out and thankfully the camera was fine. This battery has had far less use than the canon and Watson brands, but it's quality did not last. I only use it when I have dtap accessories on camera which is about 25% of the time. I did reach out to Kastar several times and received no response from them about this. It's too bad, because this system does fill a void, but maybe it's not worth it if it could also damage your camera.

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.
