This is my starter box. It's an old Rubbermaid tool box that had 2 small parts boxes that were in the lid. My power panel fit nicely in one spot and the starter in the other space. Inside are 2 12-volt gel cells so that I can run either 12 or 24 volts. This I take with me to the pits.
Back at the work area is an old flight box that I use for fueling and charging batteries.
For parts I use a 3-drawer tool box with and opening top.
