Haikelite mt03 mods? Update!

Just took a look on the driver .

It seems that it has different sense resistors (to control current) for every LED .

^

I haven't opened my wifes 4S MT03 yet, but one of the reviewers posted pics of the 2S2P driver and it had 3 separate buck drivers (one for each LED). So, yes, there should be 3 different banks. I would expect them to all have the same resistors values in each one.

Yea my driver pic is on the first pages of this threads it appears to have 2 R100 sense resistors per led? I could be wrong I’ll have to open it again and have a look.

Exactly .

It has 2 x R100 in parallel for every led . So total resistance is 50 mΩ . Adding another one will drop resistance to 33.33 mΩ .

I will have to try it today or tomorrow .

I thought adding resistors, made the resitance higher thus lower current? I forgot how it goes.
Resistors work like restriction,more ohms, less current, less ohms more current? right? So how can adding resistors lower the resistance? Unless you put a smaller resistor on top of the other?

The smaller ones or the big grey 100 boxes?

oh so maybe remove one and leave one?

haha, got ya

I will try it this evening!

Not the “grey 100 boxes” .

The small R100 resistors . You need to lower the resistance not increase it . Removing one resistor will increase resistance ( two 100mΩ resistors in parallel , total resistance 50mΩ )

yeah, I see them, I have some spare r100, laying around, from a scrapped skyray ok? But explain how can 2x r100 be 50? One would think 200? Please explain why it works like this?

Got the driver open, now it’s showtime, lets solder!

A simple search on google will help .

got 6 r100’s, or could I start by adding one only per led?

Ok, soldered on the r100 resistors, works great, not sure if it’s any brighter though have to test outside!

You added 1 resistor in each set of R100s ?

added 2 per set

definately brighter, even lowest mode is pretty bright! Not sure if it’s enough for me yet though!

You could have soldered the R100 resistor in between the other two so they are all bridged.

The 2 R100 are already bridged , in other words connected in parallel .
