    E-Jerry Can modular batteries

    We’ve already established that weight isn’t really an issue so let’s just give it two battery racks. It runs off one battery at a time so the other one can be disconnected and changed. When the one in use runs low, throw the breaker over and either change the dead battery or keep running on the aux until that one dies too if you’re in an emergency situation.

    Larger vehicles with higher power requirements can scale up the number of battery racks they have and still use the universal Grunt Power Brick just in larger quantities, and you can create a battery hauler with a generator and like 40 battery slots to carry around your fresh ones and recharge your empties. That generator might be the one thing in your squadron that still runs on gasoline, supplemented with solar.

      There’s no such thing as needing to disconnect while charging, unless you literally leave the battery behind somewhere. If you have two batteries on board, then you can use them in parallel.

        Yes but this way you can hot swap in a fully charged battery from your carrier unit without needing to power down the vehicle. You could use both batteries in parallel, but the proposed solution minimizes charging time on any given machine by sourcing it all out to the carrier and allowing constant uptime of the target vehicle by never leaving it with two dead batteries.
