Hello every one umm... I am very new at all of this and I need your help. I have a project that im working on and it involves a 120V 4.5amp DC concrete drill motor and my bike. I am using this motor because it has enough torque and I just got kinda bored lol anyway, I am having a bit of trouble finding a good power source, I had some ideas like using a car battery and an inverter but I have no clue if it is a good idea or not... Any better suggestions? Or anyway to help at all?
