I got my hands on a Thrunite R5 Multimode XPG dropin. It is the only commercially available P60 dropin I could find in my country.
Chucked it into a Solarforce host so as to run rechargeables with it. It comes on on high, but has a very short "flicker", in that it comes on, goes ever so slightly dimmer for a split second, and seems to go back to full brightness again.
It only does this on "high", the other two modes don't do the same.
Trying to wrap my head around it, it looked to me like the driver is trying to figure out what to do with the 18650's voltage (don't laugh, I'm a techtard!). To check, I put a freshly charged 16650 in there, with the same result.
I then used two CR123 primaries, and the issue disappeared.
Any ideas from the more enlightened guys as to what could cause the flicker?
