The battery life is probably not an issue in practice; the author estimates 5 hours per charge - assuming a very conservative 2000-cycle life for the pack, that's 10,000 hours of work, which is quite respectable. Yes, a private owner might keep a tractor for decades, but probably not using it for hours every single day and definitely not without some pretty significant repairs; the cost of a new 200ah battery pack is nothing compared to a diesel engine rebuild. I... Tend to suspect other parts on these things will be unacceptably worn long before the battery craps out.
