They have been used for about 8 months, so there is still 4 months of warranty. They are still on the truck but will be pulled off as soon as they sell! A couple of the connectors are a little bent due to shortening and can be purchased separte for 90 bucks for all 8. These retail for $499 @ LFP. So I will take 300 shipped obo. If you have any question just pm me with them.
