who is the oem of your raw cells?
and do you manufacture the chargers?
hmmm blf special brand chargers with the factory setup mode left unlocked for tweaking?
Hi Lagman, Can you send me PM your e-mail and ship address ? 
Yes, the batteries are also fits 18650 flashlights. Thanks for your idea.
Good idea, I have a couple of 18650 lights and I’ll test the cells in all of them.
Bella, adding a layer of shrink wrap and a protection PCB will increase the battery dimensions beyond 18mm x 65mm and may not fit all 18650 lights. Some of the higher capacity cells (Panasonic 3400mAh protected) can’t fit in all lights because they are either too long or too fat.
We design and manufacture the best quality of the battery PCB, and assemble the raw cells.
Keep supplying good quality and cheap price finished-batteries for customers.
3 colors of PVC means:
Red PVC : IMR High Drain Cells are made by LG, SONY, Panasonic
Black PVC:The Conventional Rated Capacity Cells are made by Samsung (2600mAh), Panasonic (3100mAh-3400mAh)
Green PVC: The Conventional Rated Capacity Cells are made in China
I could check the fit in the Convoy S3, S8 and M2. The XinTD X3 is also supposed to be a tight fit for protected cells. I can check my other lights, but I'd have to check them all because I don't know which don't typically fit long 18650 batteries because none of 18650's have protection. That's about two dozen lights so far. I've just started testing my cells using a hobby charger, but I'd hesitate to post my results unless they were similar to what the others were getting, although my first test appeared to jive well with what others were getting in that thread.
Hello Lagman,
Sorry, I have not got your PM. Could you pls send us ?
Hi , Brightken , we have some new coming batteries want to find some one can test batteries , if you have interesting , pls reply me , my email is :zoechen@basengroup,com . pls tell me your address , we will send free batteries to you for your test !
Send HKJ more than two! More cells = more data points = better testing. 4 at least 
I’ve been on a battery buying spree and I’m testing capacity for everything I buy with my new Opus BT-C3100 using the discharge test. I made a blog post with my test results which now includes a growing list of cells. But I try to buy everything I blog about off the shelf so that nobody can cherry pick the samples I get. But maybe I’ll buy some.
The flip side to that is it’s more work on his part. Though from what it sounds like, he pops in a battery, and three days later, it is done.
The idea is good enough, but I do not have the time for it.
Yes about 2½ to 4 days for cell, as I test 2 of each type it means about a week for each battery type. At the current time my queue testing is about two months long.

If i had to make an educated guess, i would say that the cells inside are bak 2250mah chinese cells. Not too bad, better than red brc ultrafire 400mah batteries. Just tear off the wrappers and let me know the letters printed on the metal.
ive used bak cells many times. So far so good. No explosions.
he
HKJ.has my trust along with .sending an pair to South Korea
I should be able to have a discharge graph in a day or two after I receive the cells.
And a video of the abuse attempt a few days after that.
What postal service are you using Bella to ship the cells?
sent by Hongkong post
Sorry for the late reply. I just sent you my shipping address!
Thank you Bella!
Well received. thanks !
Hello Everyone,
At present, there are 5 participants who are going to test our batteries. They are from Denmark, South Korea, France,Slovenia,U.S.A .
Today is the deadline, pls send us your recommendation or suggestion. Searching for another 5 participants.
Waiting for good news.
Best regards
Bella
If you are dead set on finding 5 more people to participate, I will take one, even though I have no test equipment. I would voice my opinions and observations, though.
