Do you have interests in testing 18650 batteries ?

Then you ain’t tryin’ hard enough…

And that’s another idea, 2 batteries heading to Denmark and 2 to Korea, please

I agree 100% if you want your batteries to be tested fully and have the specs reported in the utmost entirety and accuracy send them to HKJ to test and review

Be advised his reviews are VERY thorough and unbiased…so if you send him good batteries they will show as good, if they are junk, his tests will reveal they are junk

This is why so many of us trust his tests and reviews

I am interested in testing the batteries but am I too late?

Hi, Can you tell me the name from Korea who can test batteries ?

We highly appreciate if you could share with BLF your experiences of testing batteries.

Yes, sounds great. He is the the one we look for.

Two to HKJ in Denmark for testing, and two to ryansoh3 in Korea for destruction, please.

Hello ryansoh3 , Could you pls send PM your e-mail and shipping address ?

Thanks !

LOL. Bye Ryan… thanks for the pill.

Heheh

PM sent, thanks for the offer. I’ll make some discharge graphs before I blow them up.

Are the cells protected?
The rated capacity also seems on the low side. Do you manufacture the cells or are they made by Sansung/LG/Panasonic?
Judging by the max rated discharge, I’m also assuming the cell chemistry is ICR.

Well received your PM. Thanks.

Yes, the cells are protected which are made in China.

Damn.. sending flowers to Oversea must be expensive.. oh well time to collect donation for ryansoh3 :D

btw, before you test the batteries.. can you make another batch of HD2010 copper pills? need some for my MT-G2 mod :D

If the cells are protected, I might have a hard time torture testing them. We’ll see.

I can make another batch of copper pills if there’s enough interest, time for a feeler thread?

Are there anyone ? Warmly welcome your recommendation :wink:

I have a imaxB6 that can test the MAH under different loads. I also have an IR temperature gun to test batteries temperature at super high loads.
I would be happy to test them out for you.
If you plan to make other types of batteries with higher max draw, I suggest making the “button top” have a wider surface area for better contact

“If the cells are protected, I might have a hard time torture testing them.”
You can take apart the battery cover to access the protection board and then rip it out, or tap into the B+ and B-

Yup, I might do just that, but most if not all unprotected cells will vent when overcharged (my way.)

Hopefully the protection circuit work, and if it does, I’ll take it out.

The PCB are made by MOS(DW01 + 8205A)

I also like to test 18650 batteries and will be happy to test this one.
You can check a review I did of a protected sanyo cell here to check the way I do reviews.
I am not saying that I will do a better review than HKJ, but it’s always interesting to have two points of view.
I will test in detail the PCB (over current, over and under voltage)

I do definitely agree with that.

Another test somebody could do was to check if it fits in "all" flashlight. The lights that is most interesting to test are, of course, the lights that have most problems with battery sizes.
