Review request for HKJ [Rechargeable Batteries]

100A, I doubt it, except for a short peak.
I have ordered both your suggestions.

HKJ,

could you retest the Panasonic NCR18650B on the 4-wire test station?
It’s still the most common high-energy cell.

Also, it would be very nice to be able to compare 3 cells in the comparator instead of only 2.

Thanks for your work and great website!
I read the “multimeter design” article yesterday and learnt a lot.

Hey HKJ,

I want to thank you for your time and work. I would like to ask if you could test the Sofirn 18650 3000mAh batteries. You can buy them here in their AliExpress store.

Thanks and best regards
Tom

At the current time I have a long queue for battery >2800mAh and do not want to buy any for testing. For smaller batteries my queue is basically empty.

For small cells, think this 16340 has been mentioned before, but the IMREN 14500 and 16340 would be great - I've had both for quite some time now.

Do you know any EU shops or Chinese shops that sells them?

Vapcell is releasing a “16340 800mah 7A” cell. I guess some info will available here, and I suggested Dennis to send you some to test them.

EDIT: And it is never too much to thank you for all your works in these tests! So thank you HKJ :beer:

Sorry, no, but haven't searched yet.

The Vapcell 16340 is listed now:

I’m curious about the blue 14500 650mAh too, how does it compare to the purple Efest:

The Vapcell 18350 seems to have changed manufacturer without changing the wrapper, there was a rand about that by Mooch I seem to remember, maybe a re-test?

Generally speaking the price of these newer cells leaves me far from being thrilled. The newer 16340 800mAh and Vapcell's 18350 “1100” (cough!) are the worst offenders, particularly the 18350 which can be bought from a well known alternative source at a shockingly ;-) better price. Please lower your jacked up 18350 prices Vapcell, please.

I do not like button tops. I do not like disguising cell practices.

Cheers ^:)

Thank you very much for your suggestion.

Our main mode of sales is wholesale. There are distributors in many countries and regions.

Some distributors complain that our retail sales are too cheap to affect their prices.

The main purpose of our retail sales is that some countries do not have vapcell batteries to buy here.

If there is a local vapcell distributor, it is recommended to purchase from the local distributor.

Sometimes we also have promotional activities, with big discounts.

please keep an eye, thanks.

16340 batteries. It took a lot of time to develop them.

And large MOQ

We’re under a lot of pressure, too.

We listen to the suggestions of forum users, develop better 16340 batteries in the market, and serve users.

That’s our value, looking for the best batteries

If you think it’s a simple job, you can call these big companies efest, awt, nitecore and so on to make the latest version of 16340 batteries for you.

If any of you need 16340 batteries in large quantities, we will give you a preferential unit price.

Batteries are not only unit price, but also service, certification, insurance and after-sales service.

Our small package costs more, about $6. Arriving in Europe and the United States in about two weeks, we also have Commission on the express platform. Lithium batteries are sensitive goods, and there are many lost parts. We need full compensation.

I hope you understand us.

Have a nice weekend :slight_smile:

Would be cool to see a review of this Acebeam 21750 cell-powerbank:

HKJ …I just found that LiitoKala now have new 21700 battery 5000 mAh https://www.aliexpress.com/item/2019-LiitoKala-Lii-50E-21700-5000-mAh-Li-50E-Ni-3-7-V-Battery-for-Electronic/32999926349.html?spm=2114.search0104.3.1.562b3749kTNFSq&ws_ab_test=searchweb0_0,searchweb201602_3_10065_10068_319_10059_10884_317_10887_10696_321_322_10084_453_10083_454_10103_10618_10307_537_536,searchweb201603_50,ppcSwitch_0&algo_expid=b356b00a-063c-464e-b493-7bd7d44dcebb-0&algo_pvid=b356b00a-063c-464e-b493-7bd7d44dcebb
since AE may be one of a few choice for non US could you please test this one?

It is out of stock.

My queue for batteries above 2800mAh is 3 to 4 months, I do not really want to order other high capacity batteries at the current time.

It’s back in stock. :slight_smile:

The following is a copy/paste of a question I posted here.

A bit off topic question. May someone help me identifying the OEM of this cell:

I got a very good deal of Lii-100 charger plus button top cell. Since I knew no way it was an NCR18650B I decided to remove the button top, and that is what I got after a nice while of play with my rotary tool.

The cell scored 3256.5mAh in my Lii-500's less optimistic channel which, according to my reference data, is equivalent to a ≈3336.5mAh Henrik score. More or less, of course. Which means that cell may be some “34” model of an unknown (to me) manufacturer. May someone shed some light on this?

Thanks. :-)

Cheers

Hello!

Just a brief remark. Long ago Mooch noticed Vapcell's 18350 1100mAh suffered a cell change. It may be worth a retest of it so we can check what its current actual level of capacity, energy, discharge and power delivery ratios are.

Pretty sure Vapcell should be willing to cooperate in shedding light on this. I O:) believe.

Cheers ^:)

i have just received this cell( not from this seller), so far so good, the capacity is in range 3400-3500, and the IR( measured with 4 wires probe) is <23mOhm

i think you should check it, maybe the best high capacity 18650 right now

ps: there are a lot “interesting” cells in China, if only you can buy from there

there is a 3100mah cell and 35mOhm IR that cost lest than $2, and the NCR18650BG i got is only $2

I'm here just to ask, was the Battery capacity/DC Power Detector tested?

Cheers
