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.

How to Calculate Current From Power. You can also calculate electric current in amps if you know the power drawn from the circuit using the Watt''s Law power formula.The power formula states that the current in amps is equal to the power in watts divided by the voltage.. I (A) = P (W) / V (V). The current I in amps is equal to the power P in watts divided by the voltage V.

Neglecting this heat can cause the total heat generation to be grossly underestimated, possibly leading to catastrophic results. If the five cells in the battery were connected in parallel, the current would be divided equally among the five cells, resulting in less current per cell, a lower polarization level, and less heating.
