Extra Battery. Add this Bolt PP-5800BP Cyclone 5800mAh Battery Pack to the Bolt Dual-Outlet Power Pack for up to 2,700 additional flashes.

Powerful N’ Portable. This is a compact battery only weighing 14.2 ounces, and takes up very little space when storing or transporting. You’ll find a power indicator on the side to give an idea of how much fuel you have left.

How Does It Charge? Since this is an interchangeable battery with the Power Pack, it’s connected to the power pack itself, which can then be charged even when in use.
