The UPS and the Airplane luggage guys though will only 30 kilos (65lbs), though because of insurance/workplace comp. They wont let them lug more. at 200 kilos (440lba) you are talking splitting the pack up into 6 or 7 parts (and still be laboriously removed) or having a somewhat major operation on your car (ie, you need an Engine Hoist for the thing in one part) to change the battery. Then a forklift or something to put them on a "rack". Seems logistically like a nightmare.

That being said, the actual cells themselves are only a couple of pounds each. Would be interesting if this could be engineered to just take out something like the 100 micro-cells (at 4 lbs each), and toss em in a shopping cart. Maybe have a robot then sort and charge them in a special room full of charging racks. (like automated library book retrieval). But they would need to be built up in a certain way, and put in a housing, etc to go back in the car OK.
