Systems and methods for charging battery packs via a charger module

A system, comprising:

• a communications module comprising a first interface and a second interface, wherein the first interface is on an opposite surface of the communications module from the second interface;
• a first battery pack configured to receive a first power tool operating information from a first power tool, wherein the first battery pack is configured to removably couple with the communications module via the second interface, and wherein the first battery pack transfers a portion of the first power tool operating information and/or a portion of a first battery pack operating information to the communications module via the second interface;
• a second battery pack configured to receive a second power tool operating information from a second power tool, wherein the second battery pack is configured to removably couple with the communications module via the second interface, and wherein the second battery pack transfers a portion of the second power tool operating information and/or a portion of a second battery pack operating information to the communications module via the second interface;
• and
• a charger module configured to removably couple with the communications module via the first interface, wherein the charger module recharges the first and second battery packs through the first and second interfaces of the communications module.
