Haikelite mt03 mods? Update!

what would happen if I added even more resistors, or maybe bigger ones? How about no resistors?

Yea the stock MT03 is temperature regulated so it will step down when the LEDs get to hot.

Some times no resistors gets more power but some driver do not like it.
You can half the value again but its a bit risky to know how much power the driver can handle.

yeah but still nice to have it on display don’t you think?

Yeah wasn’t sure the mod was gonna work at first, but it apperently did! Maybe stay safe like this, maybe better driver in the future, we’ll see! I think I’m done posting for tonight, getting late here 2am!

Yea it would be but it would be a pain to install. Plus then you lose mass for heat absorption. You could place it around the tripod hole.

Few people have done this mod on other lights there are some threads on here.

I woke up a few hours ago its 11am here now.

That placement was my original plan, maybe an extra hole for a temp sensor aswell!

btw my Hg2’s only pulled 4 amps on the thorfire blf drive, weird huh?

maybe make an output jack, one for temp and one for voltage and just plug the display in when checking, remove it after.

Stock it has a timed temp check or just a general timed stepdown. After 2.5 minutes it (might) check the temp and steps down. If one were to reengage turbo after the stepdown it will not stepdown again until the time has passed. Assuming nothing is damaged by modifying the output it will likely overheat well before the timed check.

There is no constant temperature monitoring like in an X7.

Yea it does check the LED temp if its over 60 degrees it wont allow the light to step up apparently. Its not constant monitoring.

I am not sure about the 4s driver.

The reading your getting of amps is held back by your stock Multimeter leads. You need thick gauge shorter wires to plug into the Multimeter.

I didn’t check led temp or stepping up after 60 degrees, but it will definitely go well over 60 degrees on the exterior if you re-engage turbo after the stepdown or presumably if you modify the output, depending on how much it was modified it may overheat even before the initial timer.

Good morningnyou still on here?

Shpuld be fine it’s a Mastech my74

that is why I want a temp display of some sort

Tried to remove the resistors completely on my other Mt03, didn’t turn on then. Will probably do the added resistors on that one too.

Did you leave solder to bridge the connection?

No, bit accidentally broke one of the fet pins! So the second mt03 needs a new driver maybe?

Hmmm lol
Does it turn on?
Can you take a picture?
