a first battery pack interface for attaching a first battery pack;
a second battery pack interface for attaching a second battery pack;
a first load switch coupled between the first battery pack interface and a load;
a second load switch coupled between the second battery pack interface and the load; and
a controller coupled to receive a first status of the first battery pack interface and a second status of the second battery pack interface, wherein the first status and the second status include a representation of a remaining capacity of respective first and second battery packs, compare the first status and the second status by calculating a difference in the remaining capacities, and control the first and second load switches based on the difference in the remaining capacities to balance remaining capacities of the first and second battery packs.
