Sachtler will be showing their FSB Cell battery at IBC this year, a tripod or shoe-mounted battery pack designed to power small compact HD cameras for up to eight hours on a single charge.

“SB CELL is a powerful 7.2 Volt lithium ion rechargeable battery that fits directly below the camcorder. When used with Sachtler’s new FSB 2 or FSB 6 fluid heads, a stabilizer system or hand-held, it adds a carefully positioned 1.4 lb. (0.65kg) mass facilitating smooth pans and tilts that may otherwise be challenging with lightweight camcorders.

To facilitate optimum balance, the FSB CELL offers a sliding range that expands to 225mm. The FSB CELL is compatible with popular lightweight camcorders from Sony, Canon and Panasonic via optional adapter cables. The system comes complete with the global FSB CELL charger (90 – 250 VAC 50/60 Hz input).”

The FSB Cell is available at B&H for $210, a adapter cord for your specific camcorder will run you just under $80. It reminds me a lot of the Anton Bauer ElipZ battery pack system, also available at B&H for around $330 (with camera adapter).
