The invention relates to a voltage balancing circuit and a controller thereof. A voltage balancing circuit includes a direct current to direct current (DC-DC) voltage converter interconnecting a first battery having a first voltage and a second battery having a second voltage, where the DC-DC converter transfers electrical energy from the first battery to the second battery when the first voltage is greater than the second voltage, and where the DC-DC voltage converter transfers electrical energy from the second battery to the first battery when the first voltage is greater than the second voltage. And transfer electrical energy from the second battery to the first battery when the first voltage is less than the second voltage, and wherein transfer of electrical energy from the first battery to the second battery or transfer of electrical energy from the second battery to the first battery balances an electrical energy difference between the first battery and the second battery.
