As you have said most normal sized batteries will not weigh 20 kg and the problems that it seems fitting a tiny race battery can cause for the sake of quite a small weight saving would not be worth it in my opinion.
I wonder if there were 2 cars the same, both with the same power and 1 has a lighter weight battery in reality what difference it would make to performance figures?
