BATTERY PACK CHARGER

A battery pack charger comprises a housing. The housing includes a first side and a second side, opposed to the first side. The first side includes a first interface configured to receive a battery pack along a first axis. The second side includes a second interface configured to mount to a storage container. The second interface includes a coupling plate for coupling the housing to the storage container. The coupling plate is configured to be attachable to the second side of the housing in a first orientation. In a second orientation, the coupling plate second orientation is rotated 180° about a second axis generally perpendicular to the first axis from the coupling plate first orientation
