Manafont site say it can take 16340 batteries
Over half an hour — I did a run-down test. I then did it a second time, keeping closer tabs (including brief stops to measure voltage and current). 37 minutes on a TF Flame from 4.19V until protection kicked in (3.02V open circuit after reset). Current at 3.75V was 1.59A, current at 3.60V was 1.30A.
Interesting, thank you.
I just updated mine with a XPL HI. A noticeable improvement I would say. I like these XPL's in place of some of the old XPG's , brings new life to old lights.
