unregulated FandyFire HD2011 and unprotected laptop 18650...hrrmmmm....

Well I read up here:

And I ordered the 5 mode light because I want an SOS (daytime bicycling) and wanted the option of a medium in case high truly does pull 3.8-4.7a. (I read medium was 1.5-1.8a UniqueFire UF-2100 5 mode vs. FandyFire/Ultrafire HD2011 5 mode)

As always, we’ll see what I end up with when it arrives. I still want to know if people run unprotected cells @ 3.8-4.7a and how that has worked out for them for small amounts of time.
