Issues with TB6612FNG with arduino on battery power
Also, do you have the required capacitor on the output of the voltage regulator? Depending on the linear regulator, you need somewhere from 10uf to 470uf. The regulator may be...

Issues with TB6612FNG with arduino on battery power
Power is supplied by two Lithium Ion Cells - 2500mAh at 7.4v.   Difference with full speed and variable speed is no PWM. Can you verify that you have stable PWM with battery...

Thank you Kartman. I have tied both DIAGA/ENA and DIAGB/ENB and connected it to an AVR pin. As per their truth table, I need to check each of those inputs, but I do not have a way...
