1. A method of upgrading a work machine having a lead-acid battery coupled to a drive circuit and at least one motor, comprising the steps of:
a. removing the lead-acid battery from the work machine;
b. connecting a lithium-ion battery pack having a lithium-ion battery and an environmental management circuit to the work machine in circuit with the drive circuit and the at least one motor, wherein the environmental management circuit is operable to block energy directed to the lithium-ion battery pack when a temperature of the lithium-ion battery pack is below a predetermined threshold; and direct the energy to a load distributed through the lithium-ion battery pack to warm the lithium-ion battery pack.
