The NANO-F2 battery pack is a 45Wh battery in a compact form factor. It is compatible with most cameras, monitor, lights and other devices which utilize the L-series battery standard. Featuring a robust 4-cell design, the NANO-F is ½ slimmer than most comparable 45wh L-series battery pack and can handle up to a 7A load, powering even the most demanding equipment. A 4-stage LED gauge allows you to know how much charge capacity is left in the pack by pressing the button. It can be charged on most L-series style chargers.
