Recently found languishing and ignored in our inventory. Would make a great RX pack with modern systems that can handle this voltage or through a regulator for everything else. Would also be a great driver for night lights or other interesting features/projects. Was $50, We've got one inventory bin of them left for low cost pickings. Sold As Is. All packs have been checked for proper voltage prior to shipping. Due to age, no guarantee on capacity. Discontinued, non-warranty, while supplies last. SKU Number: KOK2S2040LD4CTIG
