I have a battery pack consisting of 2100 mAH, AA 1.2 V NiMH batteries connected in series (7.2 V in total). I have calculated that my system would draw a total of 1.1 A in the worst-case max current draw scenario, with most of the current drawn by motors being driven intermittently. I have a voltage regulator circuit using the LM2940-5.0 chip, with bulk and decoupling capacitors connected in all power and motor driver circuits of the system. Knowing this information alone, do you think the battery can provide a stable voltage and current for the components to continue operation and for the microcontroller to stay within operating voltage for 20 to 30 minutes?
