Covers for Xiro Xplorer battery terminal

This is a set of covers for the batteries of the Xiro XPlorer drone. Just put it on, so the terminals are protected from dust, and you can easily see which of your batteries was used and which is still fully charged. (Yes, I know about the fancy green indicator, but I wanted to add something useful to the covers...)
Available in english ('full' and 'used' ... sorry, not enough space for 'empty') and german ('voll' and 'leer')
