1. A battery charger, comprising:

  • a control circuitry configured to couple to a user interface and further configured to electrically connect to (i) a power supply, (ii) an internal power storage device, and (iii) a battery, wherein the control circuit is configured to;

    receive operating mode instructions from the user interface that correspond to a desired operating mode of (i) a base charging mode or (ii) a fast charging mode;

    receive battery-specific input from the user interface; and

    operate the battery charger in the desired operating mode to charge the battery in the desired operating mode;

    wherein, in the base charging mode, the control circuitry is configured to use power from an external power source to concurrently charge (i) the battery at a base C-rate and (ii) the internal power storage device at the base C-rate; and

    wherein, in the fast charging mode, the control circuitry is configured to use current from the internal power storage device to charge the battery at a high C-rate, where the high C-rate is higher than the base C-rate.
