Need 1 mode driver 3.5 to 4 amps.

LED Flashlights – General Info

Found this but it’s only 2.8 amps, anyone make a one mode driver putting out 3.5 to 4 amps? Driver size as in diameter size is unimportant.

Input needs to be one lithium ion, 4.2 volts.

You can stack the 7135 to increase power, better have a VERY good single 18650 Li Ion, 5 amps continuous will stress the heck out of anything but good batteries

Don't see any 3.5-5

These run at 3000

Thanks but not 5 amps, 3.5 to 4 amps. Know about stacking drivers but I suck at soldering.

Find someone who doesn’t suck at soldering :smiley:

Use stock driver as contact board and make it into direct drive. Use crappy thin wires and bad spring to limit the current going to the LED.

Here's what I would do: Take a normal 105C driver, add 3 7135s (should get you to around 3.6-3.7A). To make it a single mode you have a couple of options: 1. Remove the MCU and just short VCC to PB1 (this is what has been done in the IOS single mode driver you linked to.) 2. Program the MCU for a single mode, this way you can keep low voltage monitoring if needed/wanted.

Go with RMM :wink:

If you don’t need the low voltage monitoring and space not an issue you can also just slave the output of 2 single mode drivers. A 1A and a 2.8A but adding 2-3 chips to 2.8-3A driver is smaller.
