VaporPhreak,
Thanks for the heads up about the 5v Wow being removed from the site, I will check with my uncle about that matter.
As for the
batteries, The 5v Wow can take any CR123A size battery. That includes the Tenergy Batteries, The LifePo4s and of course the 16340 as you yourself have stated. All of which we carry on the site
Hope it helps,
~ J
