Well, in the 6 months I've been driving my Sparrow (-2 1/2 months of crash/broken/sick time) I've put 3000 miles on it. The 13 Optima YT's were new when I started. This is about 120 charge cycles where I pulled about 5KW from the pack each time (about 32AH, both numbers from the EMeter). I've had Reg MKII's installed almost the entire time. I've found that the YT's are still holding up IF they are warm! This becomes really important during my commute to work, where the last 1/4 mile is significantly uphill. The car sat all day Thursday and cooled off, and on Friday morning during that last bit of uphill, my undervoltage indicators on the MKII's lit up like a Christmas tree. I've only occasionally, on bad traffic days, had a random 1 of them light up previously. The batteries were still cool when I arrived at work, they did warm up during the charge cycle. (and I had to run the Zivan NG3 twice to get all the regs to activate - not good.)
I doubt they will last another 3000 miles (14 weeks of commuting) though. Who knows, maybe I'll be surprised! I REALLY need to find a better battery pack though. I should probably start nagging Evercell and Dragon-Sky to see who can ship me a pack first. -- John G.
