They were AW LifePO4s, probably the best battery there is out there to use in a stacked condition. I simply removed them the tube and all was fine.
WRT the DES905 Nomad I was surprised you ordered one of those instead of a screwdriver. Not sure why no one has them in stock. They are known to be problematic and the QC leaves allot to be desired, so perhaps folks just quit carrying them.
I love, love my AW14500, but my absolute favorite 14500 are IMR 14500 (you can get them here, great, reliable supplier) and the great part is they are just a little bit shorter than the AW14500s, but lasts just as long , if not longer.
