Nichia 219B in Klarus Mi1C Ti - Issues

That’s the cell, made for the S1R II. Olight 10C 16340 3amp Discharge Graph (Now Vapcell is the best 16340 I have tested)
You should be able to increase the feedback resistor to about double and bring the current down to half the 2.8 amps. Change the value from R050 to a R100 and see how that does.
If you lower the current the other batteries should work then.
