The only way to get an LT 1.5 mini right now is to cut down the tube of an 18650 LT to fit an 18350 battery. LOL.
Not to worry, though. Just wait a month or so. LT 1.5 minis will surely show up---by that time, however, L-Rider may have come out with a mini with the new Version 3.0 internals that provide a 4-amp limit. (To call this a competitive marketplace is an understatement.)
