The 800 charges in itself is not a problem, because you are using inexpensive materials and the battery would be easily replaceable.
It still comes down to how far you can go on a charge. Electric cars will not become viable if you cannot go 300 miles between charges.
If you could go 300+ miles, with reasonable performance (to beat out the semis) and can recharge in the time it takes to go to the rest room, then this may be a practical application...problem is, King Bozo Oxydol has shut down all of the coal generating capacity....
