Lumintop EDC pico dissasembly (pic heavy)

Hi there,

I recently got myself a lumintop edc pico. Extremely small light while still having a build in battery and charging port. So one day I was wondering, how did they do it. And so after some struggling I got mine open relatively cleanly to show you all whats inside.

First I started by removing the white plastic gasket that keeps the charging board and battery in place. This was quite the challenge as it was press fit in place. I had to use pliers to pull really hard on the brass knob to force it out.

then I had to leverage out the charging board using the micro usb input. This was the hardest part of the dissasembly.

Once the board was removed, the 10180 battery jumped out. apparently they placed a spring under it. The battery isn’t soldered to the charging board and is somewhat “replaceable”.


I measured the battery voltage and it was sitting at 2.7V! So clearly in need for a charge. Which in a way was a good thing as I could now check the capacity on one of my own chargers.

The capacity is right up to spec as I measured it to be 76mAh

Now it was time to inspect the charging board.


At first glance I thought the voltage was simply regulated with some passive components, which I didn’t really like. Upon very very …VERY close inspection though, I found a little microcontroller. A 57b6 chip which is a lithium charge controller. So “good enough”.

Now on to the head of the light. Dissasembly was pretty straightforward. As in most flashlights, a lockring keeps the driver and led in place, which in this case are on the same board. The output of the led is controlled by a few resistors, nothing to write home about.


So all in all I enjoyed taking it apart. I feel a little safer charging it for sure and still find it unbelievable how they could fit all this in a flashlight smaller than a triple A.

(PS: I read online that this light has horrible Parasitic drain, which from my testing isn’t the case)

Cheers.

Appreciate the detailed disassembly and photos. I’m not sure if I can do such kind of disassembly (I have a somewhat poor eyesight, especially with tiny parts…)

I got an EDC Pico which after charging, the battery self-drains in a few days. I’ve reported to Lumintop (got them from Lumintop AliExpress store) but they haven’t given me a proper response yet…

Thank you, it wasn’t easy even with good eyesight :wink:

Mine still held enough charge after a week of sitting in my bag… I did notice however, that when it wasn’t turned off far enough it can bump itself back to low in a bag.

But yea, maybe you could still open a dispute? Then they’ll be sure to answer/contact you.

Mine self drained in a few days also. After 32 days, it died. I bought it through Amazon, who told me the return period ended at 30 days. I sent 2 emails to Lumintop with no response so far. I guess worst case I’m only out $17. It’s too bad, because it’s a fun little light. People are surprised at the output on low, then you continue twisting…

That’s 2 of us having this self-drain issue on the EDC Pico… That probably means there would be more out there, just not reporting them…

Hello, sorry to hear your Pico did not work after period of use.
Please contact our after-sales from Amazon directly, and we will take care of your issue.
Thank you for the inconvenience.

Hello, sorry to hear the light is not working. Please charge the light and try again. If the problem still, please contact our Aliexpress after-sales from Aliexpress directly, we will get back to you within 24 hours.
Thank you for the supports of Lumintop.

Bought one of these when they first came out in May 2019. I use it on occasion, maybe every couple of months, never found it drained.

RobinVC, thank you for this detailed teardown post. I just received a pink one as a gift to my wife. I think the delivered battery is dead, at least charging never went green and the light developed some heat. Warranty coverage would cost me more than the whole light and I have spare 10180-s so possibly I will follow you. May be I drill a little hole in the white gasket and pry it out instead of pulling it with the electrode.
