They are lovely .
Posted on 2th, recieved in the mbox at 4th( 1 day delay from the last order, i have to rise a PP dispute for that )
Btw, i will test the driver in a relatively cold conditions this weekend- 2 days of jackal hunting, mountain here are under -10/15 degrees( C ) atm
105c based drivers gave me headaches last winter, Olight m22 driver too
I think that significant increase of li-ion batteries ESR on low temp. is cause of your problems,but you didn't mention what kind of problems you had,so I assumed low current?
105c just stopped( was in c12 fl) and after i heated the tube it started working again, but stopped right after 3-4 mins
Olight M22 changed modes on a random base
As far as i can remember the batteries i used last year – Panasonic 3400B( or it was 2900 pf?)
I already installed one of your driver in C12 and i am testing it right now, but the outside temp is only -3 atm, not cold enough( working exellent atm)
I don't see any reason why drivers shouldn't work ok at those temps.,but ALL li-ions really suck below 0C,mainly because electrolyte ionic conductivity drops drastically; here's some data for NCRA:

Yeah, its like that for Li Ion batteries
At temps under 10-15 degrees electronic components start behaving wierd, especialy sensor type ones, as an engineer in construction company i see it like every winter
Anyway, i didnt had any problems last night, the temp fell under -13
5amp driven U2-1A running at -13 degrees …start is at least at 1600lm
Just did the PayPal transfer for 3 pieces.

Have these been posted out yet?
If so any idea what postage time is like at this time of year?
Typical shipping time for EU is 3-5 working days,so you'll probably get your package very soon.
