I got here now a idea from Easy B, who wants to build a S2+ with rotary tailcap
So I came up with the idea that it may be possible that the Imalent tailcap of my dead driver fits the S2+
and it fits
even better the S2+ tail cap fits the Imalent light as well
Now as I got the news I get a full replacement light as Imalent cant provide the tailcap, which contains the driver, as spare part
I need to get me a S2+ tail cap
I opened up the press fit contact board of my Imalent DM21TW
as i expected there is a diode for the charging from the tailcap driver
and bleeder resistor on that contact board
So with a S2+ tail cap I could get this light back to life getting a Bistro TA driver
from this thread
I may help you with your rotary S2 triple
I got here a defective Imalent light
The tailcap fits the S2+ body, just the tube needs to be shortened 2mm so the tail cap gets over the oring
When the replacement light arrives here I can send you that tail cap
