802025 li-ion battery? Curious, I was the other day browsing stuff in AliExpress and that sort of flat format unshielded batteries piqued my interest. Some examples:

2pcs/lot 5000mAh Li-polymer Rechargeable Batteries 3.7V 6060100 Lithium Polymer Battery For Digital Products
Supply lithium battery lithium polymer Rechargeable battery 602535 600 mah 3.7 V For MP3 MP4 MP5 GPS PSP MID Bluetooth Headset
1/2/4 Pcs 3.7v 600mAh Rechargeable Li-polymer Battery 602244 Li-po Ion Batteries For PSP DVD MID PDA Gps Recorder Selfie Sticks
1000mah lithium-ion polymer battery 3.7 V 102050 For MP3 MP4 MP5 GPS KTV household battery amplifier audio computer microphone
Polymer lithium ion battery 3.7V, 402030,502030,602626,702035 can be customized wholesale CE FCC ROHS MSDS quality certification

Interesting stuff, could be used to overhaul old appliances or DIY new stuff but I wonder how good that @#$% actually is.

Cheers ^:)

Yeah, you can buy all kinds of sizes.
Interesting for building tiny lights that are NOT cylindrical.
Buy a bunch of those micro USB charging boards and you’re half way there.
(well, maybe not half way… )

So i’ve been playing a bit with this tiny TINI, and this LED is very nice.
Orangey warm and plenty of real red.

But the UI and the buttons of the TINI suck a little…
2 second press for ‘ON’…
The momentary ‘turbo’ also has a considerable delay…
I put some foam under the buttons so they’re not pressed as easy as stock, but i think i over did it…

Light leaks through the seams too, also through the mode button, which gives a cheap impression…
The chrome will wear off the plastic frame too… Already a weak spot on the bezel…
Under the chrome the plastic is white / translucent… That’s just dumb…

So, the TIP is simply a better light and only about –33- 50 larger*, with more than twice the battery capacity and a better UI.
But the tiny size makes the TINI very cute though.

the TINI is 33% smaller than the TIP.
0.66 x TIP = TINI
1.5 x TINI = TIP

Nice little mod. Did you see the overhaul that tterev3 did with a TINI, putting MELD into it? He and CRX ought to collaborate some time. They both have insane skills working with super small parts! tterev3’s mod shows that if you’re brave enough, you could swap the MCU and get any UI you want.

EDIT: I just looked through his thread and saw that you commented on it, so I guess you already saw it.

Jerommel · 2018-12-04T03:43:37.000Z

Yeah, i saw that MELD mod.
Amazing crazy soldering job.
I’m not THAT brave, and i lack the knowledge to do something like that.
But he didn’t swap the main LED.

Part timer… :laughing:

Jerommel · 2018-12-04T04:14:21.000Z

LOL

But the stock XP-G3 does a good job in the TINI too.
Low Vf, very bright, no tint rainbow effect.
Simply more light output, bigger ‘wow factor’ since the TINI is so… well, tiny.

Just had a look in that topic, and it should be doable, to swap the MCU.
I don’t know, we’ll see how this light holds up in time.
The little buck driver is definitely cool.

Nice mod . You have a lot of bare LED.

Jerommel · 2018-12-04T05:31:51.000Z

Yeah… especially 4000K

DENGOH · 2018-12-04T05:42:42.000Z

What do you think about SST-20 3000K and 4000K? I am torn apart which one to get for a KD P60 drop-in.

everydaysurvivalgear · 2018-12-04T07:59:08.000Z

Awesome mod mate my EDC is using the same SST20 on a triple board running at 3 amps. They have a good tint but i think i prefer a 4500k tint more.

Great build and great report Jerommel, thank you for that.
Might try to put LH351D in mine if I manage to fix the switch failure….

There are some cylindrical LiPos as well.
My favourite example:

Hobbyking

Turnigy Nano-Tech 900mah 1S 15C Round Lipo

Turnigy nano-tech 900mah 1S 15C Round Lipo. The Turnigy nano-tech round single series cells are the perfect solution for many applications where space and weight are at a premium. These round Lipoly cells can be soldered together to make custom...

It’s my favourite because:

it’s from a good manufacturer, not some random Alibaba listing
specs are outstanding, compare that to the best 14500
they stopped making it though

Haven’t tried the 4000K yet, actually i’m waiting for that order to arrive…
But apparently the 4000K tint is above the BBL, so it has a slight green hue.
Had i known this before i ordered them, i wouldn’t have ordered them.

Nice mod and info thread. Thank you for sharing.

Neat that cathode linked thermal pad emitters can be easily swapped in this light.

Sirius9 · 2018-12-04T21:12:35.000Z

Nice job, and this is the money shot:

The dome of the 351D may be too large for the little TIR.
Also, the Vf of the 351D is a bit high, and the TINI has a buck driver, so it will be less bright when the battery starts to run low.

thanks for the details and the pictures!

Jerommel · 2020-01-11T01:36:52.000Z

Pics re-uploaded, which seems to take ages…
Imgur uploads slowly….
Can’t figure out how to put pics in albums either…
But hey, it’s free.

MascaratumB · 2020-01-11T01:35:08.000Z

Jerommel:

Can’t figure out how to put pics in albums either…

In your account, go to IMAGES (top right).
Where you see the “ALL IMAGES” tab (left side), click the arrow down, and it will open a list. Click the “+ New Album”

When you’re going to upload the images (right side, again), you can choose “Add to album”, just select the album you want and also the “resolution” (“Auto Resize” tab) you in which you want the photos to be ulpoaded

Hope this helps
