Hi, I am currently going to college at a technical school in Missouri, learning how to be an electrician, and for one of my classes I am required to make a project of some sort that incorporates electricity and that would be a practical solution to the every day world. I started brainstorming and thought of an idea to make a portable jump starter for your car, if your cars battery was dead or low, you could hook another battery to it and jump start your car. I know they sell something like this at auto stores, but I want to make one for myself. I have seen YouTube videos of people jump starting their car with a lipo hobby battery, and thought I could do the same. I have a lipo remote control car battery that I would like to use for this which is rated at 11.1 volts and 7600mah at 75C. Would this battery be enough to jump a car battery? I was also thinking of a way to safely do this, and the ability to use it more than once. I understand that if you were to get the car started with the battery I have, the cars alternator could charge it and could cause some safety concerns, I also thought of a way to prevent this would be to add a diode to the battery I would be using to jump the car. Another one of my questions would be what ratings on the diode would I need to successfully do this without blowing myself up. I understand that a cars alternator can charge a car battery up to 14volts or more. Is this too crazy of an idea, or would it even work? Is there anything I am missing here?
Any help is appreciated!
