and do you know is this time set by/in MCU, would it decrease if I add (or replace that 334/330Kohm) resistor on top of that capacitor (for faster discharge)?
It’s a good little driver. Even though it is DD it does not seem to draw too much, 3A is perfect and 1A on low. The thing I like so much is this simplicity. High or low, no nonsense.
I received mine yesterday, about 2 weeks after I ordered it.
Tested mine in combination with one XM-L.
Freshly charged batteries (AW 2600, protected and NCR18650B 3400) it pulls up towards 3,3A on the tail. When voltage is a bit lower it will soon be closer to 2,7A.
Mine is not regulated, that is for sure. I would expect higher current if it was direct drive though.
On low, mine pulls 0,7-0,5 depending on the battery voltage.
I have not tested it with cells that are quite low.
Mine have next memory mode. Not a fan of that, but not that annoying when only having 2 modes.
Its a little delay when changing modes where the light is all the way off.
Its a slight “whine” on low (like a nanjg 105C on low, only different whine).
I have not checked out efficiency.
Mine came with spring and wires.
For the price, I cant complain. I did not have high expectations either. But it seems like there are variations out there on this driver.
Compared to the one marcl got its easy to see that its not the same. Low is lower on mine, and I have next mode memory.
Based on my first impressions, its a decent 2-mode driver for the price.
