Battery installation on the BMW R1100RT

Hello together.. Has one of you already shifted a battery from you? And that is that I drive a BMW R1100Rt.. The problem I have is that I have no power connection in the garage and so that it can also not connect over winter. So I have to remove the side cover every time.. and that’s for…. So I thought to myself why put – I don’t just build it in the side case.. Has one of you already made this and can give me tips??? The cable are at the end provided with an eyelet (to screw it to the battery..) I had before the new cable then what goes to the battery with an eyelet on each side.. The one eyelet then stops for the battery and the other eyelet with the already existing with the help of a screw to connect with mother.. As a battery connected to cable.. Cable end also with an eyelet and then red with red … Eye on eye and then connect with a screw….. Isolated finished Would that work? or how thick would be attached to the battery?
