Been a while since I've popped into this thread, loving the progress and the videos Bram!
I've been using an SSB battery for a while, they really are amazingly light and small. Mine weighs just over 1kg and starts my car every time. I just disconnect the negative terminal when I park up so it doesn't have a constant parasitic draw, which I was told they don't like. For that, among some other reasons they're not well suited to daily drivers. Who needs that kind of weight saving in a daily driver anyway though..
