Single 18650 XHP50 Driver! Self designed driver, check it out!

After a little more reading, I am going to have to force PWM. This sucks a little bit, as my board will now need an additional ground trace. Ugh.

Any reason why this great driver shouldn’t work with a MT-G2?

You really should work with some of our driver guru’s like RMM ( Richard from mountainelectronics), led4power or wight. (Or the other(’s) which I might have forgotten at the moment)

BTW, great work!!

It will work just fine! any 6V LED will work with this, I’d have to change a resistor for forward current limiting though, but not a big deal!

Any update on this? :bigsmile:

Cant wait to see some more info/tests.

Latest update:

Sent another revision to fab, should get it next week. It uses bigger components (only one 0201), and forced PWM instead of PFM, which should (in theory) get us all the way up to the 3A. The light is in my car and I’ve got a night beam shot but it’s nothing special, you all have seen plenty of them.

Will post updated as I can!

Thanks for the update. Im looking forward to reading of future developments.

Very impressive! :slight_smile:

If the efficiency is halfway decent this should result in a substantial gain in run time over using 2 X 18350 cells in 1 X 18650 lights.

I’m going to add a dummy load on a reclaimed 18650 LG cell, If I can I’m going to “pull” this driver up to the 3A and see what run time is.

very nice. can you make this to fit AA lights ?
like the k5

NICE!!! Great news! Where’s the sales thread? :smiley: I’m in for one at least.

Pretty sure it is just short of impossible. Just the controller is about the size of an AA battery. Add the coil to that and it wouldn’t be a drop in package. I could make it in a double board, but I feel like a 17mm drop in would be a better choice.

Great Job!

That’s exactly what I need for my moddings!!!

Liking how this is looking.. Excellent work on it!

I’m in for ten at least :wink:

Haha! What would be a fair price?

Parts alone are over 12….

If You produce 200 the price sinks! 8)

Well for sure, but then what if I only sell 10 to you, and the random 1-2, it is one of those “nice idea, not a lot of market for it” ideas. I will check what the first price break is, i’ll test for thermal, and maybe get these bad boys for sale end of feb.
