1. A battery booster for jumpstarting a vehicle having an external battery, the battery booster comprising:
a set of electrical conductors configured to couple with the external battery or with an engine that is electrically coupled with the external battery via a set of battery clamps,
wherein the set of electrical conductors comprises a positive electrical conductor and a negative electrical conductor;
a power supply configured to supply a starting current to jump start the vehicle via the set of electrical conductors,
wherein the power supply comprises a plurality of lithium battery cells arranged to form a lithium battery having a positive terminal and a negative terminal;
a boost switch positioned in-line between the power supply and the set of battery clamps on one of the set of electrical conductors; and
