C100: Genuine C100 Bat. BP-955 for 29$ ???

I have a few Wasabi batteries for my C100s which work well for the price. No run-time meter on the battery.

This below looks like the same thing you linked to, except it sells from Amazon under the known brand name of Neewer, so seems more reliable than a no-name from Ebay.

This may quickly turn into another thread where people say things like, "Why save a little money and risk your camera blowing up?" and then will fail to provide references for confirmed cases of cameras ever actually being damaged due to off-brand batteries.

I have two of the big Canons and two of the no names. Both work fine if you can live without the time remaining. Since the big batteries last close to a whole shoot day on the C100, I feel these batteries are a good value.
 
How the lack of the time remaining chip works, no warnings at all ? the camera just shuts off during the record ? with no capacity meter warning at all ? full - low ?
 
You just get the four battery segments. If you are on the last segment, yes, it will just shut down but you have to do some math too to know your hours of capacity.
 
I managed to run down a no brand battery on my C100 recently. Just before it died the tally lights started flashing constantly. Is this an indication that the battery is about to die or something else?
 
I have some Neewer BP-955 equivalents and they work ok in the C100 and C300, not as long as Canon batteries, but for the money it's ok. They even work semi ok in the C500 in 4K at 23.98. However, when I shoot C500 60fps 4K and 120fps Half RAW 4K they die very quickly, so I need to stick to Canon original batteries at those frame rates. I bought them as a just in case buffer when far away from power.

It means your camera is about to EXPLODE!!!
Nah, but in general you do have to be careful about a sudden loss of power since the files being written need to be closed, so if the power suddenly cuts off you might lose the clip that you were recording. I'm not 100% that's the case with C100, but it's fairly common across most devices that record video files. Some of them will save just enough juice to close the file, but it's a risky maneuver.
Best practice is to not let the battery get that low.

I've had batteries die while recording before, I think using both Canon brand and off-brand batteries, but maybe just with the off-brand ones. When you turn the camera back on, the C100 asks if you want to repair or recover the data. I select "Yes," it then takes a minute to close the file (which can be a pain to wait a minute while in the middle of a shoot, but probably better than having selected "No" which I've never tried doing), and after it's done, the file is good to go and I've never had any issues.

Good to know. Thankfully I've never had to push it that far!

So the flashing tally lights mean the power is about to drop or not?

Slow flashing (once per second) means you are running out of SD card space, fast flashing (four times per second) means you have run out of SD card space, the battery is about to go flat, or the camera has had a whoopsie (an error warning). You'll also get warnings for all of that on the LCD screen too.

thats interesting that you had good luck with the Wasabi. my experience was the opposite. they started out good (i bought 2 large batts) for the first 2-3 charges then went downhill at the speed of light in an almost laughable way. whats interesting I'm must own about 40 Wasabi batteries for my EVF's (5D style batt) and they have been very very good and have just recently upgraded to a dozen new ones since the older ones are 3-4 years old. I'm actually a Wasabi fanboy lol! maybe i had a bad batch of C100 batts?? hard to say and i don't doubt that your experience has been favorable. this goes to show though that there is a big inconsistant aspect to these batteries that was enough for me to avoid and just pay the money for the intended battery. plus to risk data being written without failure makes good business sense.

in the EVF's and LCD's i go with the cheep ones since i need so many and have had exceptional luck. i decided to just pay the price and not have to worry about it. i bought 3 Canon largest batts and have enough for an all day shoot with no worries.
