I swear into this diy FET DD driver as the best for certain setup(1x18650, 1x emitter setup) maybe not perfect for this new Osram emitters (but it could be reworked if we restrict current over the fet to around 4.5A) but for old XPG2 in mentioned setup is really, really the best, unbeatable…
The problem I have is that AK-47 C1 driver (firmware with high,med,low no memory effect) disappeared from the market… So for me that means “GAME OVER”.
I would take 17mm regulated drivers (4.5A on high) but I need high, med, low mode without memory effect so it always starts on high… I don’t want to mess with re-flashing and reprogramming or any kind of fiddling(short press, long press, 5 flashes etc.) to get into that…
So we all have wishes and preferences… My vote, but only for mine mentioned type of setup goes to above mentioned type of FET DD driver.
