Olympus BLN-1 Li-Ion battery (1220mAh) for OM-D cameras (accessories)
Pricewise a shock, but I need 3 batteries when I go on tour, one in the camera, in the grip of the OM-D and one for recharging :-) So I come to events (my daughter's wedding) after 1400 shots not in Compressibilities and always have enough power.
