@AlloyCat, thinking back I probably found my problem, I was in creeative, which means all the batteries were just on 100%. Thank you for the quick answer and for all your sick builds :)

@Max
Thank you for the feedback!
The default Batteries are set to be in Auto mode, meaning they will not charge until they deplete their powers.
You can turn them into recharge mode via control panel, all batteries are under the same group.
I didn't use any energy affecting script.

Is there any power management script in the vehicle? Because neither the reactors nor the engines seem to charge the batteries.

Thank you all for the kind words :)

Tir Na Nog? If the cockpit doesn't have a beer dispenser, I will be surely disappointed.

Very pretty.... amazing design.
Gonna test it in-game.

great work dude!
