Sound cools. I'm also interested in Serum's battery design. I think if there was some sort of system on the truck with a few plugs, and then a housing to which the battery gets secured and plugged into. Then the housing itself can be attached to the module on the truck, and secured via a body pin.
This way, you can have say, 2 or 3 housings per truck (and then just switch out batteries within the housing, if you need to). This way you only need a few housings, and not one housing per battery.
I look forward to seeing it in person.
