Calculation of heat generated by a battery pack
Heat is generated from other than effective power. Effective power is used to drive the load. Thus, "4.2V * 3A * 30/60h" is a straight calculation of (though need some more considerations) power we are drawing from the battery, but not the power to generate heat. Heat is generated from "inefficiency", offset to an ideal power source.
