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
DOnt send? Come on! Ask Banggood! They always said we have in stock , sure…and after you pay they start…actualy we have only 26 pcs….on second thoughs we have only 21 pcs….oh wait, we have 17 …jk ofc, but thats the very truth
A tiny copper piece on the mosfet helps alot though
