Abstract:
1. An apparatus for heating fluids, the apparatus comprising: a number of lithium-ion cells positioned within a housing; a first connector positioned on a first end of the housing and operably connected to the number of lithium-ion cells, the first connector configured to receive electrical power from an external power source; a second connector positioned on a second end of the housing and operably connected to the number of lithium-ion cells; a heating element having a tube for transferring fluid, the heating element configured to connect to the second connector, receive electrical power stored in the number of lithium-ion cells, and heat the fluid by converting the electrical power into thermal energy; and a controller positioned within the housing and operably connected to the number of lithium-ion cells and the second connector, the controller configured to monitor a rate at which the electrical power is received by the heating element and limit an amount of the electrical power received by the heating element when the rate reaches a predetermined level, and wherein the controller is configured to electrically disconnect the second connector from the number of lithium-ion cells when the first connector is connected to the external power source.
