To late, already got the notification email.
Mistaking 32650 for 26650 can happen, not an issue to delete.
But just for your information, there are 26650 with a real Capacity of about 5000 to 5500mAh out there. And while those are not IMR Cells, the 5A this Light consumes are not a problem for "normal" LiIo 26650.
(just taking a guess.. 3.8kLm should be about 2.5A per LED for one Cell, resulting in 10A total. Two in Series would be about 5A.)
5000mAh-5500mAh range 26650 is definitely possible. Above 6000mAh hasn't happened today, maybe in future.
As for output, 3800 lumen is possible but it is quite optimistic. If 5A is needed to go into the LEDs, the current draw from battery can be as much as 30% higher due to parasitics lose. 30% isn't exaggeration at all at 5A kind of load for 1 series of battery. But I guess, even with 30% lost, 2 hours of runtime with 7000mAh 32250 (if exists) is still possible in theory. I can't way what the lumen output of this light is until I can make some measurement, but pushing 5A across is a lot of current in a handheld application like this. It is impractical if possible at all.
