Possible and could be the cause, but I think there are too many unknowns to make any real conclusions here.
EDIT:
I really would like to get to the bottom of this because I have been thinking about driving an MT-G2 with a Dry and 3S cells. It seems it has to be excess voltage or thermal failure. Current seems unlikely. Please check out my logic and correct and/or build on a realistic theory.
| # of Cells | 3 |
| Likely voltage ater sag (guess) | 4.05 |
| Total Voltage | 12.15 |
| Tail Current | 7 |
| Watts Produced | 85.05 |
| Driver Efficiency (guess) | 0.8 |
| Watts to emitter | 68.04 |
| Emitter Vf at 16 amps | 8 |
| Amps to emitter | 10.63125 |
Obviously, last 2 lines don't match. That is the point. Comfychair showed here that it seems to buck pretty good. That seems to increase the likelihood of this being a thermal failure. Has anyone else tried to push an MT-G2 hard with the new Dry driver?
