Canon BM-E2 Battery Magazine
The BM-E2 Battery Magazine is dedicated to the Canon PB-E2 Power Drive Booster, which is used in conjunction with the EOS-1V, 1V HS, 1N, 1N HS, 1, 1 HS, and 3 SLR cameras. It is a spare or replacement item for the one originally included with the motor drive, and holds eight AA alkaline, Ni-Cd, or lithium batteries for use.
