I have created a ham radio/computer gobox for emergency use when bad weather hits.
I can go into areas with out power and communications and provide ham radio and packet service for people in need. The go box I have has 2 radios 2m/70cm and a low power cw rig. It also has a low power computer and four 5v 1A powered usb ports. I have two 12ah batteries in the go box mainly for backup and temp use. in my car I have a extra 12v deep cycle battery in parallel with the car battery.I have this battery switched so I don't strand myself by running the car battery down.
How can i charge the two 12ah batteries from the cars 12v system and from 120v house/generator power not at the same time of coarse? I need to do it as cheap and safe as possible and in side of my gobox so it all is self contained. I am looking for a circuit that I can build to do this.
Thanks for your help
