1. A rechargeable battery jump starting device having a back-charge diode system, the device comprising:
a first battery;
a second battery;
an electrical control switch electrically connected to the first battery and the second battery, the electrical control switch configured to switch between a parallel connection and a series connection for the first and second battery; and
a back-charge diode module connected to the first battery and the second battery, the back-charge diode module configured to protect against a back-charge to the first battery and/or the second battery after a vehicle battery has been jump started,
wherein the back-charge diode module comprises a first channel of diodes accommodating current flow through the first battery and a second channel of diodes accommodating current flow through the second battery, and
wherein the back-charge diode module includes an upper frame member, a lower frame member, and a center frame member located between the upper frame member and the lower frame member, and wherein the first channel of diodes are connected between the upper frame member and the center frame member and the second channel of diodes are connected between the lower frame member and the center frame member.
