Bob is right. I've actually met the people who assembled the battery packs and sold them to Woods Hole and was shown photographs of the setup. They aren't the consumer labeled products, but they took a bunch of normal batteries, spot welded them together in large strings and packaged them into a single unit. They get used once and then tossed. ***************************************************************** Embed Inc, embedded system specialists in Littleton Massachusetts (978) 742-9014, http://www.embedinc.com -- http://www.piclist.com hint: The PICList is archived three different ways.
