I believe the short answer is 'No'.
From what I've read / seen, it does not, although I don't yet fully understand the limitation myself.
The light features in-light charging, and the 'port' (opening) in the body is inside / behind an O-ring sealed threaded collar, which is cool. It appears however that there is no USB-C connector mounted in the body, but rather the USB-C charging cable plugs through the port / opening in the body directly into the cell itself, rather than a connector integral to the light housing / body. The cell may also be charged outside the light w/ a USB-C cable.
This light uses the SL-B34 cell, which is apparently only compatible with this new light at present time. The statement about its uniqueness is: "
- Self-keying battery ensures proper alignment of the charging port
SL also states to only use that cell in this new light, as it's not cross-compatible with any other light. Looking at the available photos I've seen I can't really tell what provides that indexing / alignment of the cell with the charge opening in the body.
I believe the current 'standard' SL 18650 is the SL-B26, which is fine in all my SL 18650 lights. This is not that cell.
A similar charging approach is implemented with the ProTac 2.0, which uses a similar SL-B50 cell, which also provides keying for alignment with the charging port in its body similar to this new light, but in photos of that cell, I can see how the keying is provided.
It appears that in-light charging through an opening in the light body, inside an O-ring sealed threaded collar, but with cable plugging directly into the cell inside, with keying providing the positioning / alignment between the cell and that opening, using a bespoke cell, is a new design solution / strategy being employed by Streamlight, and that does not bode well for new lights using 'standard' 18650 cells, as has been the past strategy (excluding Strion, which has always used a bespoke cell).
I think that's the 'long answer', based on what little I currently know;-)
Cheers!
