Hey Rick,
Though I'm getting a killer deal on the bike, it's production #178 from 2012. The bike sat in a display window for most of it's life, and has a total of 200 miles on it. I think it's still basically "new" and they are selling it to me with full warranty (starting from the day I pick it up next month). I suppose the biggest concern would be the battery - is there a shelf life on the stock battery pack that I need to be concerned about? Is there any servicing or battery conditioning that needs to be done to a bike like this that's been sitting idle for a couple of years?

Dave, your battery may have degraded a little, but with your CA set at 65Ah, get on the throttle wide open hot off the charger and tell us what your volts drop to. If its not dropping below 71 Volts WOT hot off the charger, your battery has probably got some serious charge/discharge cycle life left in it. Lifepo4 chemistry has a theoretical battery life of 2000 cycles no more than 20% SOC and up to 7 years. But that data is for Lifepo4 rated at 3C and less. Stealth is tight lipped about our packs C rate but I am betting that its between 5 and 10 C, Stealth rates our packs for up to 800 charge cycles so following that rule of thumb, I would estimate our packs are good for 3-4 year shelf life provided we don't discharge to LVC Cut off and never charge before storage, that will ruin any battery including SLA. My pack is about two years old, I have Bomber 143, with around 300 cycles on it, and it has degraded some but it still working very well especially with the 5405. I would say I have another 1.5 years of life in it before I either need to drop my CA to about 40ah so its not hitting LVC hot off the charger, or just replace the pack. With Bomber 178, your bike had to be built some time in August 2012, so your battery is newer than mine, I am betting its good to go.

It's been a few days since I asked the dealer to confirm if Stealth honors the warranty for batteries that are over a year old (on unsold dealer demo bikes). I also sent an email to Michael at Stealth about it. I agree with you that probably isn't anything to worry about. That said, I"d feel better getting written confirmation from the dealer and/or Stealth about their policy on this.
What's the going price on a replacement LiFEPO4 battery pack these days?
