The M18 and M12 vehicle charger allows users to charge battery packs on the go from the 12V or 24V DC outlet of any vehicle. The charger communicates with battery pack to manage individual cell voltage， temperature， and charge status. Featuring REDINK Intelligence， it communicates directly with the battery to monitor cell voltage， temperature， and charge status to optimize the performance and extend the life of the pack. As an added level of communication， the charger has protective electronics that automatically shut down the charge to prevent excessive discharge of the vehicle battery. Charge time is 30 to 60 minutes.
