Bypass not advisable.

have any of you tried bypassing all the springs successfully?

Which model? I believe it’s fine to bypass all the springs on the 70.2 version. (Edit, if it’s the new factory driver this might burn the big FET) You don’t want to bypass any of the springs on the xhp35-HI version.

i ordered a 70.2 MT09R and im planning to bypass all the springs with 20AWG

Is this flashlight really 25000 lumens?

No, Haikelite exaggerated a little.

BlueSwordM · 2019-04-07T03:28:40.000Z

Yeah.

You’d need spring bypasses and top LED bins only to achieve 24 000 lumens with a calibrated tube.

The MT03 TA is a more accurate representation of what it can do with spring bypasses.

Andybibbville · 2019-04-07T03:38:39.000Z

Thank you all for the info.

For those who use the original MT09R driver (not the TA or Lexel driver), it is highly recommended to exchange the SIR800 MOSFET by a better one that can be driven up to 100A (e.g. Infineon) if you plan to bypass your springs.

You don’t mean the “original” driver (that one was rubish), your talking about the current, stock driver designed by TA. That’s the one that has the weak FET.

There’s 4 drivers for the 70.2 version and it can be hard to keep track.

Exactly, that’s what I meant to say. Thank you Jason! :+1:

MT09R or Astrolux FT03?

So now I can also confirm it MCU and FET on the HL drivers for this light are faked from some chineese manufactory

MCU has not even unusual markings it has even a spelling error missing an S in the type
“ATMEL20U”
“TINY85”
“7 digit batch number”
while the original Atmel has
“ATMEL 4 digit batch”
“TINY 85”
“20SU”
“triangle”
and 3 rows batch data on the back side where the fake has nothing

I have measured the FET used on the red MT09R driver
its labeled like the original Vishay cant tell any difference
Original @10A and 4.7V Gate
https://eu.mouser.com/datasheet/2/427/sir800dp-93246.pdf
SIR800 —> 2.6mOhm —> 26mV —> 0.26W
the SIR800 has pretty stable resistance down to 2.5V Gate voltage so its a good FET for 1S lights as well

Fake
@4.7V Gate like the MCU delivers to the FET
I got 38.3mV 10A —>3.8mOhm resistance

@3V Gate
I got 165mV 10A —> 16.5mOhm

@2.5V which the original should have around 2.8mOhm as its gate voltage gets very deep till 2V pretty stable
I get only 2A with reasonable input volatge and the stunning drop on the FET of 1.1V
so here the FET has 0.55Ohm

Conclusion

the FET HL use is definately some sort of fake which wont work on any 1S driver well
with 4.7V on gate it has a usable resistance but still this FET is like the MCU fake

So i just completed bypassing all my carrier springs with 20AWG, using x4 VTC5A flat tops, did a 35s run on max output and my stock FET is still working! 20AWG in driver spring and all carrier springs

scr79423 · 2019-05-01T18:56:32.000Z

i recently got a set of the Murata version of the VTC5As, strangely i measured 2,000 lumens gain over my regular VTC5As in my MT09R all springs bypassed, I’m not sure if my regular VTC5As are fake or genuine but aged cells?

MT09R bypassed = 18433lm Murata VTC5A flat tops

MT09R bypassed = 16390lm VTC5A flat tops

Sigh… Haikelite has good product lines, but the brand is cheap to its management as they don’t mind using fake components and caused so much trouble to customers. Mine MT03 TA had faint leaking light during off and after spending month negotiations with CS to get a new driver from Haikelite and I paid for shipping, the new driver was having same issue. Desoldered and measured both fake SIR800 to be having around 50Mohm of resistance with 0Vgs, they are not completely open.

I replaced the FET with real SIRA60 and it works fine. Also replaced the FET of another driver with BSC009 and put it into old MT03 II, it works fine too. Now these two MT03 are always in momentary mode with 5clicks, have had blasting them side by side for 1+ hour in accumulation, almost burn my hands as they are really hot.

Good thing was Haikelite forced me to learn how to use hotair gun. After watching some YouTube video, i managed to solve it to good ending.

Measure the internal resistance of those cells, the values should indicate which cells are aging more.

I recently bought the MT09R from HaikeLite‘s new store on AliExpress. It still uses the SIR800 MOSFET. In factory condition it can do about 50-60% of its advertised 25,000 lumens. Please read here for further details...

Meanwhile, my HaikeLite MT09R XHP70.2 P2-3C arrived. Its outer appearance is flawless and well done. [image] [image] A good friend of mine dismantled and optimized it. HL already uses double springs. However, these springs are not well soldered. The inner springs seem to get loose fairly easy as these are not soldered to the PCB. [image] [image] Advertised maximum output: 25,000 lumens Results from a test (in factory condition) with different batteries: Samsung 30Q: 12,500 lume…

Genuine or fake SIR800? The exterior looks the same, but they are different internally. This is the point everyone has been making.

Is there any way to tell them apart except for testing it in detail as Lexel did? However, it did not burn with all springs bypassed.

I don’t think so.
