Offering Four Canon LP-E6 battery slots, and 1/4″-20 mounting threads on the sides, this Power System allows you to provide extended power to a wide range of cameras and accessories in various mounting setups. It features two 2.5mm DC output jacks that let you connect out to two 7.2V devices at the same time using appropriate cables. A variety of regulated and unregulated cables are available for compatibility with different devices. Two 1/4″-20 threads, one on each of two sides, allow you to use rod clamps and shoe mounts for mounting. Two batteries are required to be attached on one side at all times, so you can swap out one side at a time. An LED indicator remains lit as long as sufficient power is available. Made in the USA.
