Its actually load of small batteries rather than one mashoosive one isn't it?
How heavy would a removable one that does, say 75 miles, be?
They average about 250 miles so 75 miles is about 3 1/3 of the full amount. 3 1/3 of 540kg is about 160kg. They literally cover the floor and are stacked on top of each other in parts. They have over 7000 cells wrapped in 16 modules. Each module weighs nearly 34kg. You would need to take out, carry and exchange 5 or 6 of them to get your extra 75 miles. Can see loads of elderly with their caravans in tow managing that.
