MF01 Mini / MT07- Mod/Upgrade - Copper Heatsink Cover Plate

Also, I am even willing to pre-pay in order to secure the item in advance, if necessary.

Looking forward to your response.

Want one

Donā€™t need to worry, youā€™re on the list (post #2) for the batch, you will surely get one.

Pre pay is not easy to handle for me, I will provide info to everybody on the list via PM as soon as the payments can be done and afterwards the shipping will be started.
But unfortunately it will take some time, it depends on the supplier / manufacturer.

I hope the first half of the batch can be shipped before christmas.

Interested. Two pieces please.

Interested for 1.

2 for me, please! :slight_smile:

1 piece for me please. Thanks

For information, updated status in post #1 and list post #2.

When are the isolation stickers mandatory?
Are these also needed if button top batteries are used?

interestedā€¦
Shipping cost for Greece ???

Strictly speaking they should not be. There is a raised stud that touches the positive pole and the battery shouldnt touch the copper plate BUT! it could. In some cases if you drop the the flashlight the stud will press the button top down and insert itself into the battery. In that case you could short the battery positive pole right next to the negative. I wanted to send you a link to a thread where they discussed how those button tops could compress during flashlight falling but couldnt find it. You dont have to use the stickers but I would. You can also consider epoxying one side, or liquid electricians tape and stuff like that.

Thank you. :+1:

Interested for 1. if possible.

Tracking shows that my test sample is at our local post office. I am at work night shift now. Tomorrow I think I will get it and start testing it :wink:

Interested in 1 please.

Thanks for the update, looking forward to your results and review of the MF01 mini.

The first Batch of 100 pcs. is fully reserved by the interested, see the list in post #2. If somebody of them will jump off, there could be some parts available from. Iā€™m not able to stock up the batch, the price agreement with the supplier/manufacturer was done for 100 pcs,heā€™s got already the material and the production is started now.

I will put you and other interested in a second list for a possible second batch, but at the moment there are no plannings for this. The realisation depends on the count of interested, I doubt we will get another 100pcs list full. In case the batch will be smaller, the price will be higher. But we can try it.

First test happened.
Short result: it works

More detailed:
The edge thickness is a bit high. It leaves a gap between head and tube but around 0.5mm and O-ring perfectly 8nside head so not much deal. I will polish the edge which contacts the driver but without that I see a big improvement. First I made a reset on anduril to try as it is out of the box. Stock ramp max was 2200 lumens. With plastic it dropped instant to around 8-900 and creeped back up and then downā€¦ With copper thing it has around 20% drop from 2200 lumens then went up to 2000-2100 and stayed there for 3 and half minutes. After that it slowly reduced output to 750 lumens at 7 minutes. The hottest temp under this test was 43Ā°C on head. I will recalibrate temperature and set 50Ā°C limit for stepdown and see what I got. Now 4 pieces of liitokala 26650-s are in charger to start all test runs with full battery. I made a video of installing and I will add runtime graphs to it and upload that this weekend or early next week.

Thanks for your first impressions.

Please tell us which version of the MF01 Mini / MT07 you tested. Due to your output levels, I guess the 5000K or the 6500K.

Well, this is kind of a ā€œItā€™s not a bug, its a featureā€ thing :wink:
A small gap between head and tube is necessary to ensure a proper contact of the battery tube to the heatsink plate. In stock case, there is a gap between the plastic cap and the battery tube while itā€™s completely screwed in.
.

Do you used Thermal compound for this first test?

Mine is MF01 mini 5000K.
Yes I used thermal grease. Canā€™t tell the exact type. We use at work for industrial electronics heat sinking. It is working well in my dedomed Imalent MS18 so it will do the job. I show full assembly with applying thermal grease in video.
