Battery charging apparatus

A battery charging apparatus comprising:

• a case having a bottom surface and a vertical wall attached to the bottom surface in a substantially perpendicular configuration to define a volume of space above the bottom surface for housing a plurality of batteries with one or more connections facing upwards and one or more connections facing downwards;
• a case cover coupled to the case to secure the plurality of batteries within the case;
• a first plurality of conductive elements above the bottom surface of the case and below the plurality of batteries and in contact with said connections facing downwards on the plurality of batteries;
• a second plurality of conductive elements beneath the case cover and above the plurality of batteries and in contact with said connections facing upwards on the plurality of batteries, wherein the first plurality of conductive elements and the second plurality of conductive elements connect the plurality of batteries electrically in series by circuitry resulting in a positive battery terminal and a negative battery terminal;
• a positive contact electrically connected to the positive battery terminal;
• a negative contact electrically connected to the negative battery terminal;
• a connector for electrically coupling with an interface to a target battery, said connector having a positive lead removably coupled to said positive contact and a negative lead removably coupled to said negative contact;
• and
• a charge control circuit coupled between said positive lead and said positive contact, said charge control circuit including a switch with a first and second position, wherein said first position allows current for charging the target battery to flow in a first direction from the plurality of batteries to the target battery, and wherein said second position allows current for recharging the plurality of batteries to flow in a second direction from the target battery through an inductor regulated by a voltage regulator to the plurality of batteries.
