I am developing a 12 VDC version of an AC powered product that we currently sell. This system will be driven with a 12 volt automotive type battery. Connecting the battery backwards will fry a lot of components. I am considering a diode on the ground cable to prevent reverse current flow. However, this type of battery is capable of sourcing a lot of current. Therefore diode failure and heat are two considerations that I have. I am interested in how you might handle reverse current protection in a circuit such as this.
Thanks
