Abstract: 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.

Abstract: The present disclosure is directed to a battery pack charger. The battery pack charger may include a housing for holding power conversion components and charging monitoring components. The battery pack charger may be configured to mate with and charge a battery pack. The battery pack may include a housing for holding a plurality of battery cells. The battery pack charger housing may have a width dimension and a length dimension. The battery pack housing may have a width dimension and a length dimension. The battery pack charger housing width dimension and length dimension are generally parallel to the battery pack housing width dimension and length dimension, respectively, when the battery pack charger is mated to the battery pack.
