Abstract:
1. 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 removably coupled to the case to securely enclose the plurality of batteries within the case; a circuit panel 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 circuit board beneath the case cover and above the plurality of batteries and in contact with said connections facing upwards on the plurality of batteries, said circuit board comprising a positive contact and a negative contact, wherein the circuit board and circuit panel connects the plurality of batteries electrically in series by circuitry resulting in a positive battery terminal and a negative battery terminal, wherein the positive battery terminal is connected to said positive contact and the negative battery terminal is connected to said negative contact, wherein said positive contact is further coupled to a first diode in series with at least one resistor enclosed in a thermally conductive and electrically insulating material, wherein said first diode allows current to flow from said plurality of batteries to said positive contact, said circuit board further comprising a second diode coupled between said positive battery terminal and said positive contact, wherein said second diode allows current to flow from said positive contact to the plurality of batteries; and a connector for electrically coupling with an interface to a target battery, said connector having a positive lead connected to said positive contact and a negative lead connected to said negative contact.
