This mod will add an Electrical Transformer that will convert energy stored on the equipment grid of vehicles into a form of energy that can move these machines.

Simple Huh ?

Just research the technology, create the transformer along with a few batteries and add a way to recharge then ( some Fusion Reactors, Solar Panels etc ) and that's it, no need to put fuel in their slots anymore.

Ah, you also has an option for making this stuff available Early-Game.

This mod works better with Vehicle Grid by Optera, you should use it :)

Thanks a lot to PFQNiet ( On Factorio Forums ) for helping with 99% of the code :)
