Rufusbduck, how is that possible? the A6 driver is 2.8-4.35v input, but the 2S cells are 8.4v.
.
Fin17, did you ever get a new driver for this?
I’ve also been researching for a light I’m building with 2S cells for an XHP50.2…
- For a FET/DD driver he can use this one, (FET Driver w/zener mod):
FET Driver - 17mm
- For a linear, constant current driver he could use this, (QLITE 6V+ Zener Mod):

However, I was informed the QLITE is more suited for smaller cells such as 2*18350, for the larger cells I was recommended this driver:
- MTN-MAXlp HP Buck driver: 17mm MTN-MAXlp HP 1A-5.5A Low-Profile Buck Driver - 5V-18V
.
Another option, and one I’ve been looking into is the LD-B4HV from led4power:
It has some really great advanced features, one I like is the ability to user program it for either direct drive or constant current for the high mode.
Plus you can also adjust the output current a few amps up or down.
Installation is a bit more complex as it takes a special mcpcb because the mosfet component is externally mounted there.
It also can utilize a temperature sensor that can be mounted on the mcpcb as well.

Anyone have any other suggestions?

I came here when researching for the CF FX-17A driver from KD, because it’s 17mm and I was curious about it.
Fin17, besides the nasty driver’s whistle you’re hearing in the middle mode, is there anything else you didn’t like about the FX-17A?
