For the average Joe who is going to go out on a 5 day trip MAYBE twice a year at best, the difference between 1000 cycles and 5000 cycles is a moot point, unless you plan on passing it down to your grand kids.
But I understand how attractive the Lithium route is and what you built is top shelf stuff in a great package and perfect for going out on multiple trips with little to no maintenance.
