Hey there, I only just saw that this mod existed a few days ago, but I was wondering what it would take to add compatibility between our mods. I took the 'batteries as fuel' approach like most of these mods do, but I added an 'internal power reserve' feature that allows for eschewing the batteries entirely. It seems like there's potential here for behaviour like the old, /old/ electric train mod from the 0.15/0.16 days that was powered by electric network coverage on the tracks but could also run on internal power between electrified sections of the network.
