For battery connectors I use copper ore brass plate you can buy from electrical shop and springs I`m waiting for a local supplier to
send me the price on manufacturing the springs & cable 1mm can handle 8Amp 1.5mm - 12Amp
So after I have seen @capetocuba Red Sky Cruiser and what you guys are doing I "sommer" jumped and
did a box and will fit the rest of the goodies tomorrow night and finish it off
