A battery pack system is disclosed. The battery pack system includes a
battery pack having batteries arranged in a plurality of parallel groups
that are connected in series. Each parallel group includes a plurality of
the batteries connected in parallel. The electronics are configured to
drop the current at which the battery pack is operating from a first
current level to a second current level one or more times. The second
current level is lower than the first current level. The electronics can
drop the current from the first current level to the second current level
during the charge and/or discharge of the battery pack. In some
instances, the electronics intermittently drop the current from the first
current level to the second current level during the charge and/or
discharge of the battery pack.
