And here's another one.

I have got a tesiyi 45a battery with 3000mah capacity the last week. I have ever seen a battery with 45a, I want to make sure it is true, anyone would like to test it?

Oh yeah, this is in my list of notes.
So I'm trying to prove/disprove that Shenzhen Tesiyi Technology Co., Ltd. makes batteries.
Three problems:
1. Can't find a patent online
2. Can't figure out what the parent company is. There are a mega-f-ton of Shenzhen ______ Technology Co., Ltd's. (Any of them tied together?)
3. Not motivated to keep looking. Meh.

Im down for playing a little detective!

One of the problems is that I don't know enough about international business. R&D. Marketing. And the overall battery manufacturing process.
All I can say is that something doesn't smell right here. I mean, you don't see Samsung setting up shill accounts on forums or typing fake, breathless testimonials on a rudimentary branded website.

You don't give up huh? No one wants your shitty potentially deadly batteries. Give it up.
OK, I Googled that.
www.geezle.com.cn/
That page is titled "Shenzhen GPower Industrial Co., Ltd."
Below the title are some pics of branded GPower batteries. And then this...
Um. What?
You claim to make your own batteries. Then why are there Samsungs, LGs and Panasonics on your page?
We're never going to get a straight answer from you, are we?
Summary of this Post
--There's a company that makes batteries that isn't Samsung, LG or Sony. (We already know there are at least a few.)
--I still need to find proof that the Tesiyi yellow/black-wrapped batts are not rewraps.
Certifications
--I pulled 10 off the Tesiyi website. Most looked like certifications for safety versus "Hey look, we make batteries." One was a UL certificate.
The UL Page
--ul.com. Bottom-right of page. Under Resources / Online Certifications Directory.
--I put in the UL File Number.
The Search Results
--Oh goody. Yet another different company name. Not Shenzhen Tesiyi. Not Shenzhen Geezle. It's Shenzhen BOFUNENG Battery Co Ltd.
--It says component. I called UL. Apparently it says "component" because it's a battery they're testing, not the thing a battery goes into. I asked the dude if it was possible that UL was checking singular battery components like protection circuits. He checked a few things, and said they were checking actual batteries. And that they check the battery at the factory in China.
--There's more information in the BBCV2. (The circle on the right.)
The BBCV2
--This lists the crap that UL checked. I cropped the pic.
--The dude had me click the link that I circled.
The BBCV2 Guide
--Another cropped pic. But yeah.
Standard 1642
--The Guide Info above had this link.
--It's a standard for lithium batteries.
http://ulstandards.ul.com/standard/?id=1642
Why I'm Doing This
Because I'm annoyed. Might do more later. Who knows.
The next thing would probably be trying to tie Tesiyi, Geezle and Bofuneng together. And any other company names that crop up. And they'll crop up, trust me.

Oh, one more thing for now. Pretty sure I haven't mentioned this yet.
Reverse Image Search
--I did a reverse image search on three of the factory pics from the Tesiyi website. Google and TinEye.
--Wanted to see if those machine pics were lifted from another website.
--Came up with nothing, which was a partial relief. The pics don't even link back to the Tesiyi website.
--But. I've been having trouble getting hits lately from cropped pics. I think the only cropped pic I've successfully found recently is from one of Whiskey's cropped avatars. Found the whole pic and posted it as a joke.

You're giving me flashbacks from when I was a PI in international corporate law.
Chinese records can be the causative agent of consumption of mass quantities of antacids.
Got 2 personal rules.
No Chinese batteries.
No Chinese e-liquid.
No amount of graphs is going to change that.

Welcome to today's edition of
Trying To Piece All This Together
If you remember, Tesiyi says their factory name is Geezle. Geezle's website says "G Power."
G Power
I Googled "G Power 18650"
The first thing that came up was a Mooch post on ECF.
https://www.e-cigarette-forum.com/f...test-results-too-inconsistent-to-test.721841/
His bottom line:
In my opinion, the performance of this version of Sigelei's 35A 2500mAh cell, using a GPower cell, is too inconsistent to test. The other version uses the VTC4, rated at 30A/2100mAh. This time at least they use a 2500mAh cell. But, the performance between the two cells I have was so different that I have no idea which might represent the true average performance of Sigelei's.
Testing was stopped as soon as I confirmed that the two cells I received were so different. Both appeared identical. I cannot recommend buying the Sigelei battery.
Mooch's Safety Chart
The only GPower battery on it is the Sigelei, listed as "CNT," or Could Not Test.
G Power Batteries
The first one I saw for sale was $15 from some random U.S. website. VUBot was also pimping one in January.
FT sells a GPower 3100 mAh IMR. FastTech's test showed its capacity as 2680.1 mAh.
Can We Link This G Power Info To Any Tesiyi Skepticism?
I don't know. That's the problem. Since my last post here, Oracle has started a new thread and (accidentally?) called himself out as being linked to the company. But he never addressed these recent questions.
Geezle's Website
Post 118 shows a pic of Samsung, LG and Panasonic 18650s on their main page. One is our beloved Samsung 25R. All have the GPower icon next to the batt photos. Still have to figure out what all that's about.
How Are the Shenzhen Companies Linked?
Was going to do that today, but got sidetracked on G Power.
