Well, only a nut would buy a $600 MSRP light and choose to potentially void the warranty by modding it. I guess I'm a nut.
Planned mods for the X6:
1) replace the little proprietary connector with a weatherproof standard connector. Probably this one:

Replacing it on both ends will make it easier and quicker to connect (the proprietary connector isn't terribly convenient). These standard waterproof connectors are also more easily replaced should they break or get damaged in some way.
2) mod #1 also leads to mods #2 & #3. Mod#2 is to take this cable

and replace the CLA female end with a female Deutsch connector from above, thus allowing me to power the light directly from a vehicle cigarette lighter socket.
3) the addition of this

will allow me to run the light straight off a vehicle battery.
4) since the Olight ac-dc adapter takes a 120-240v input and provides a 12v 6A output for the light, all the above should work fine shouldn't it? In addition, I'll either replace the plug on the Olight ac-dc adapter with another Deutsch connector, or perhaps, get a cheaper adapter that takes ac and outputs 12v and at least 6A.
Mods 1-4 will make connecting and disconnecting the light far easier, plus easily allow me to run the light from a vehicle cigarette lighter, 12v battery or ac outlet.
Further mods (might have to send this to vinhnguyen54 for these):
5) XM-L2 T6's on copper SinkPads, plus any additional potential heatsink or heat dissipation mods.
6) replace the 2600mAh cells in the proprietary battery pack with Panasonic NCR18650B 3400mAh cells (~30% increase).
Maybe
7) since the cells are 3s2p, it's potentially possible to build a custom backpack carried battery pack with something like 12 or even 24 18650's or any multiple of 3 (to be charged with a hobby charger) that could provide anything from 260% or greater runtime.
