Another update. Got a pair of Samsung 50E 21700 5000 mah batteries yesterday and ran some voltage test. It’ll go to Turbo at 3.55 volts but only last a second at this point. Drops out of high at 3.25 volts. Drops out of medium-high at 3.14 volts. Drops out of medium-low at 3.08 volts.

It’s becoming a favorite light of mine and if it proves very durable it’ll be a new duty light partnering the Pflexpro 2 mode 3.8 amp light.
