Has anyone reverse engineered a schematic of the Mini ML-X? Since purchasing the Mark II, I was thinking of modifying the Mini and possibly a Quark I own to make it accept a 3.7V rechargeable battery. I'd need to see what the limiting factors in the design are and thought I might not be the only one thinking about this possibility.

I'm tired of buying CR123 primary batteries and foursevens new charger and high discharge battery is a nice solution.

AFAIK, the circuit supports 3.7v. 4sevens never encouraged the use of RCR because there is not enough mass in the light the properly cool down the led. If you use short bursts of less than 30 seconds (on high), there should be no problem. Low and mid can run run fine on an RCR. I almost only use RCR in my 2 minis.
