Who It's For

Photographers who own Olympus OM-D E-M1 Mark II, OM-D E-M1 Mark III, OM-D E-M1X, or accessories like BCH-1 and HLD-9 and want a budget-friendly spare power solution will find this kit useful. The fully decoded batteries that report charge level make them especially appealing to travel and event shooters who rely on accurate remaining time on camera LCDs.
