pkcell 14500. surprise! rated 750mah got 844@500ma

Tempted as well, but I will wait for those 14500 first.

Has anybody ordered Pkcell 16340 ?

my 10440 and 14500 are fine.
need someone with test gear to test the others.
or some to find their way here.

Got 4 X of their 18350 900mah. Iā€™ll discharge test two and report back.
Iā€™ll do some ceiling bounce test with a cheap lux meter against Keeppower 18350 too. Havenā€™t got the Aspires yet

if i had something to use them in i would have gotten some.
looks promising if they are anything like the 14500.

got these in my watch list pending reviews from you guys :slight_smile:

Subscribed :wink:

Discharge four 18350 at 0.5a. Got 888, 892, 893 and 909mah.

Also did a ceiling bounce test with a cheap UNI-T luxmeter and Emisar D4 XPL. Pkcell got 240 and Keeppower got 284.
I got four Pkcell for $10aud. So they are a bargain. The same seller on ebay even sells 12 for $23aud.

Good numbers for a first 500mA discharge. :+1:

give them a few cycles to break them in.

14500 cells arrived today.

They all came with 3.84V.

First test on one cell, charged to 4.2V@300mA (4.19V after 5 minutes), shows 831mAh at 500mA discharge current. Cut off voltage 3.0V (as specified in the data sheet).
Nice numbers for the moment.

2nd cell shows the same numbers and as I am pretty shure all the other cells will do the same, I will not continue testing.
snakebite did the test @1A. IĀ“m sure my cells would just confirm his numbers.
It would be interesting to see some discharge diagrams in near future.

So far I recommend this cells.

i need to order more of both the 10440 and 14500.
they all left in restomodded vintage lights with friends.

Would be nice if HKJ tested these.
I guess for ā€˜high drainā€™ (but not too highā€¦) usage the Windyfires are still the best?
But for ā‚¬11.13 i can get 5 14500 PKcells with free shipping, which is nice. :slight_smile:

HKJ said that he had 14500 in the pipeline. But not 10440.

hi Box, what was the name of the ebay seller?

Hey mate.

Awesome, thanks. This looks like it could be good, they have NiMH batteries and all!

Theyā€™re in my AliExpress cartā€¦

:+1:

I got a few of the PKCell ICR18350, IMR18350 and ICR14500 batteries from AliExpress (fortunate to have ordered them last month, when they had free shipping via Turkey Post; just checked right now, and theyā€™re only offering expedited shipping options US$40+ Fedex ā€” seems like Turkey Post is not shipping batteries anymore).

What current should I charge them with? Standard charge current? Rapid charge current? There doesnā€™t seem to be a spec sheet. The sellerā€™s page in AliExpress only indicates max continuous discharge current (2C for the ICR type, and 10C for the IMR type). How about discharge current (when testing discharge capacity), is 1C too high or still OK (for the ICR types).

based on the seller item page description:
PKCell ICR14500 750mAh max continuous discharge current = 2C = 1.5A, cut-off voltage = 3.00v

PKCell ICR18350 900mAh max continuous discharge current = 2C = 1.8A, cut-off voltage = 3.00v
PKCell IMR18350 700mAh max continuous discharge current = 10C = 7A, cut-off voltage = 2.75v

So far I did discharging of the above batteries at 0.25A discharge current and also getting around 800-900mAh (the ICR18350 900mAh and IMR18350 700mAh seem to have similar capacity?)
