Re: Long range lithium conversion

Glad to hear that, Tim, as I'll admit to being just a bit concerned about some of your massive investment in cells being lost, after my recent discovery. I think you had the advantage of having evidence that the cells were tested, so presumably charged, before they were shipped. I've no evidence that this was the case for mine.
At just over a year old, all you'll have lost is a small bit of age-related capacity. No one seems to be able to pin this down for LiFePO4, but I'd guess at a loss rate of around 5% per year would be about right. Certainly, my experience with the electric bike pack seems to show that any capacity loss with age is quite modest for this chemistry, much less than for other lithium cell types it seems.
