Charging winch when doing pitstops!

[◄Chuck►]

The battery idea was never meant to be realistic or whatever, it was purely meant to prevent over-usage of that feature. And since the term and logic was already in place (from the speedtrap battery) is seemed logical to use it here as well.
As for the actual question, I am undecided but I tend to leave it as it is, as it indeed limits its usage and therefore allows other people (lets say with full batteries) to step in.
The end, however, often comes as a surprise, I think that could be worked on.
