You could put 30 extra cells in a trike, but why would you bother.

My example is in this section for a reason. Any sensible design probably doesn't need any extra cells at all. There are far better things to use you space and weight allocation for.

We average a combat encounter every 50 miles in the trucking campaign. Rarely will one of our vehicles go more than 100 miles before it needs significant repairs that take far longer and cost far more than a recharge. A recharge also allows a sensible break from driving.

Fuel tank capacity is a big deal for large gas plants as the MPG is punishing and the gallon capacity to Spaces ratio of fuel tanks is pitiful. Since bigger electric plants come with more PUs built in it isn't really an issue. I can't find any comment about electric mileage or extra cells in ADQ so I presume it is another of those aspects that just doesn't figure in the vast majority of other players games.

Fun to explore, but whatever ruling you use isn't going to break the game (or apparently invalidate any published design).
