Best Batteries for a Cafe Racer + Charger

It ain’t easy to find the perfect battery for your motorcycle.
I tried at least on my current motorcycle (during one year) 3 different batteries. And still with nothing else connected to my bike, only for starting and running. I had big issues finding the perfect fit.
Not only that I needed a specific size -> battery box underneath my swing. I also needed enough power for my old school motorcycle.
