help finding driver

Flashlight Modding and DIY Parts
1

I was wondering if anyone has ever seen this driver sold anywhere. In my opinion it’s a really good one for mods and a potential alternative to nanjg style drivers. It’s a 17mm five mode (H-M-L-strobe-SOS) driver with memory that sets in if you turn it off for more than 2 seconds. I got around 2.8 amps on high at the tail cap.

sorry all i’ve got are these lousy photo of it. All I have is an iphone camera. There’s nothing on the battery side other than the spring and no names or marks that I can see.

I got this driver from an xm-l c8 that I bought 2 years ago. I think the c8 was from tmart if i’m not mistaken.

any help is greatly appreciated!

I don’t think you’ll find any like that one now as they get upgraded all the time, but there’s
this one AMC7135*8 5-Mode Circuit Board (Nanjg 105C) 2.8A
Or there’s this one, AMC7135*8 5-Mode Circuit Board (Nanjg 105C) 3.04A
Or there’s this one Qlite Rev.A 7135*8 Multiple Modes Circuit Board 3.04A
And i’m certain there’s others i don’t know about so stick around for other blf people with more and possibly better alternatives.

A lot of those C8 drivers are just really low PWM with Direct Drive high. The Nanjg drivers have a lot of advantages as they have the lower PWM (very nice) and a regulated high (so longer runtime with less heat on some cells). I have a C8 with the DD high and the tailcap current depends on the cells I use. Good cells will provide 4+ amps but that's harder on the cells, and overheats the emitter with diminishing output as heat increases.

I have a ultrafire c8 with this driver as well, often the spring and the switch reduce the real life current to a nice driven light…
If both things get upgraded 4A are possible so I like this driver too. Good and cheap. But I have not seen it for sale yet anywhere.

Mine was next mode memory…
I used a very small resistor on top of the cap to make it a one mode driver with the ability for modes with a very very short tap.

There are similiar style drivers with a controller and small transistor(some have this additional EEPROM)available but not the real deal. That why I have plans on building one.

Cool thanks for the input guys. Yea mine has really nice memory (off mode memory) which I prefer to the nanjg style (on mode memory).

Anyway no bother if it can’t be found. Thanks for all the help

If anyone is interested, i’ve found that kaidomain sells this exact driver.

5 mode - H,M,L,S,SOS, last mode memory, about 2.7 amps on high. Not too shabby in my opinion. :slight_smile:

Wonder if there is a resistor bridge to kick up the power from 2A to higher

need better pics though

To me I don’t want this kind of driver, because of bad modes, bad PWM (presume it is), and relatively low current on high mode. I want direct drive on high mode instead. J)

Haha yea do you mean the new custom nanjg fet drivers? Those are definitely superior. Still this is an option for those who can’t program their own drivers.

The nanjg driver with FET mode is surely great, but I have no time and skill to do that. The East-092 driver or some other unknown cheapo direct drive driver can work well for me already. I always expect these budget lights have crappy mode group and PWM frequency with their stock driver so I hope that at least their high mode is direct drive. :slight_smile:
