I’m looking for single mode driver (1-mode - just bright) for XM-L2 LED… Current should be some 2A or more from Single Li-Ion 18650 (~3V - 4.2).
I like Low input voltage warning in Nanjg 105c multi mode drivers, and I want something like that, but only with 1-mode…
This could be a good driver: 4* AMC7135 LED Flashlight Driver + few extra AMC7135 chips… but it does not have Low input voltage warning…
The flashlight will be for my relatives in the countryside, and the problem is that they have several unprotected 18650 bateries…
Another idea that came to my mind - maybe I can put in the P60 drop-in (under the driver) Protective Circuit Board from Li-Ion battery? Is it possible something like this?
As it’s only one mode, the driver you linked to lack micro controler (MCU).
What you can do is getting a Nangj 105c driver from DrJones, as his lucidrv have a lock mode and battery monitor, you can :
- select the brightness that suit you (as 8*7135 at 100% can be too hot to use)
- lock that mode so it stay on it like a 1 mode driver
- still have a dimming (as a warning) if voltage drop below 3V.
It’s a bit too much to have 1 mode AND voltage monitor but it would work.
Or getting all the equipment to reprogram 105c driver and program 1 mode and blink when voltage is too low.
Ok, it seems that DrJones driver really might be right for my situation…
And how about my idea about PCB board directly in flashlight (between driver and LED)? or it is possible at all?
