Thanks Baker
That was informative and convincing. I have searched a lot for this info and it was right in front of me but could not do the math
Anyway my conclusion is that TWOS needs some refinement , and the Stock game is way off (as ubisoft usually is) as I measured some 110km range with a 12-17 hours recharge with a fully upgraded motorman with my tweaks you get 160 km (which is the hystorical range of 90nm) and can recharge in 8-10 hours.
I did not expect ubisoft to modell battery life/cycle perfectly as it is a very broad issue from mostly temperature to the tiredness (life cycle) of the battery a lot of variables should have been calculated, but being so off really pisses me off.
