Thanks, Foy and Jeff:
This 26650 battery discussion is turning into quite a mystery. I've sent an email to Hank at IOS asking him to clarify what cell he is selling on his site. If he is in fact selling two different chemistries, that needs to be noted and they should be broken out separately and I find it a little disturbing that you got two apparently different kinds, Foy. The King Kong battery I received from CNQ was labeled ICR26650E.
Further discussions on the 26650 cells are taking place here: https://budgetlightforum.com/t/-/7473
