Batteries | From laptop battery |

We used these batteries from an old Laptop to store the electricity which is generated from the motor.
These 2 batteries are connected in a series connection to get the higher and the required voltage(the voltage= 2×3.7 = 7.4 Volt) which is suitable for the output of the motor which is 7.5 Volt
