XT-60 Battery Plug Cover

I use these on the end of a discharged battery so I know which ones to charge when I get home. Red seemed to be the appropriate colour for that considering I don't want to accidentally plug in a discharged battery. A friend preferred green to put on a fully charged battery and that accomplishes the same goal.
No rafts... no support and printed the what it shows makes it have extremely tight fit so they don't fall off.
