Battery booster

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 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;
• and
• an internal heater configured to heat the power supply or a portion thereof;
• 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
• at least one processor configured to output a control signal to close the boost switch as a function of one or more parameters of the power supply, the external battery, or the vehicle.
