Thank you for analyzing the driver!
I have been impressed with the performance, stability and efficiency of my E05II, and would love to buy such AA-boost/14500-buck drivers for my projects.
Might you have any plans to produce another batch of your excellent drivers or to partner with someone to make them available at larger quantities?
A note of caution for those considering the titanium version: it can’t be locked out mechanically by loosening the head; a product of not being anodized, I suppose. And unlike the OP, I found it quite prone to accidental activation. So, it sits on my nightstand rather than riding in my pocket. Unfortunate for a light that I rather like.
