The Canon BP-955 Intelligent Battery Pack (5200mAh Lithium-ion) communicates remaining running time and wears data back to the XF-series Professional Camcorders, so the user is well-informed at all times. On the outside of the battery, four LED lamps allow battery life to be viewed.

Switched over from a 7D to a C100 the other week and had to buy an extra battery. Thought the price was high at first, but when I realized how well the battery actually performed I felt it was definitely worth the price. 3+ hours of use per battery. Sometimes longer. Great purchase overall.
Bought an extra BP-955 (same as ships with Canon C100) because the larger batteries were out of stock and I knew I'd need at least double time for a quickly approaching conference shoot. The charge time wasn't horribly slow but it did seem to take a bit longer than some other manufacturers to reach full. That said, I have been VERY impressed by the longevity of these bad boys. Even in near constant shooting I'm routinely getting well over 200 minutes with the C100. The push button indicator is also very handy when pulling the battery out of a case or to save previous drops by leaving the camera off between shoots.
