I expected only Bistro HD initially, having a Narsil option is nice.
Not sure if this is the right place to ask…but I want the boost driver in my UT02. And I want the light to stay rechargeable.
What are the options?
Is it possible to use the stock charging module or should I order some other and try to fit it in?
Great drivers Lexel :+1:
Need more info about Boost drivers…
Can this driver boost current from 1S and 2S (both) or is it 1S or 2S only? This is interesting for flashlights that have 1S and 2S battery tubes (like Jaxman X1 and Convoy L6).
Is it side switch, tail switch (or both) capable?
What is the height of boost driver?
thanks
I think those boost drivers deserve their own thread. Great job! :+1:
im with you.
want the rechargeable option with ramping mode 
this depends how the charging board is implemented and if there is space left with the 7mm high inductor
I think to remember a separate board for USB, but if it still fits with new driver has to be tested
I got a UT02 here to mod this way then I can tell you if it works or not
still got no time to finish the boost drivers testing and optimising parts
What about TN42 when modded to CFT-90?What are the specs?
I wait when some guy get the first BLF-GT mod with the CFT-90,be sure that the mod is troublefree, see some beamshots etc, so as to follow,but in the meantime I ask about the TN42 as well. 
I have TN42, MF01, HaikeLite and GT PCBs in production in China shipped with DHL
for the first prototype I have parts laying here reflow and then I know if all is OK
25-40A buck drivers with a chip specially designed for Luminous LEDs
Any updates on my big CFT90 driver?
What’s the highest output you can get on the 17mm boost drivers at 12V?
3A from my calculations
30mm driver got more functionality added and a little bugfix
nice work. Very curious about the new boost drivers.
Skilhunt H03 added
this board is already stocked
24-30mm
new design with added LED resistor to support new 2s 2x2 LED Boards and a little bugfix
this board will be stocked soon
Bad news for the 1 cell boost drivers someone bought all 300 available chips from Mouser and new stock will be delivered in June
no other distributor has avalable stock right now
Hmmm I wonder who that could of been……
Which chips?
Grrrrrrrrr!
The MP3429 is in stock, Lexel, and will work just fine (my driver uses that).
How's your driver coming along?
MP3429 works for XHP35, but for 6V XHP70.2 I want 7A Output
Well it's working fine on my desk 
(albeit driving XHP50s at 6.5A instead).
