LiitoKala 26650-50A 5000mah 26650 - great first impressions

Here are the specifications for this battery (I did not find them in the original comment).

That $22'99 (Ouch!) I-Joy 40A 4200mAh is just another niche product for preppies with horrible price/performance ratio. Meh…

Cheers ^:)

Is that $22.99 per cell :open_mouth:
If so that is about the price of 4 Liitokala 26650”s.

Yep, in fact it is $3.40 higher than the last 4 I just bought & received. I got 4 for $19.59 at GB. :slight_smile:

Hello!

Excerpt of a report about my findings on internal resistance for these batteries, published last wednesday 2016/09/07 here (e-cigarette-forum):

0K. Just to let you know I've done some smartass battery IR testing on the sixpack. With a LiitoKala Lii-100 charger (pumping close to 1'05A, maybe ≈1'047A, no lab equipment sorry), my standard multimeter and this mV accurate voltmeter:

Well, the voltmeter drains 10+mA (I think the eBay ad claimed 11mA).
All the cells have shown 23ish mV load/no load deltas (measured with the wires under the flat top button, it shouldn't have any significant impact at this current though). The numbers look pretty good, 22-23mΩ of resistance for these cells. Clearly 20A continuous 26650 cells, with 5+Ah of capacity.

Just remembered…

Cheers ^:)

matches with my findings.dick smith esr reads .02
unbeatable price/performance on these cells!

best thing is you get to build it.

Sorry for bumping this thread, but i had ordered the same liitokala 26650 from aliexpress to use in a flashlight.
The thing is that i need to put 4x26650 bateries in serie.

After the fact of ordering and receiving these batteries i read i cannot put them into series?
Or can i with the help of something like?: Assuming a coin wont work? :slight_smile:

I nice blob of a silver based solder will do better m8, ways ways better

Doesnt need to be silver based solder its not stainless, 60/40 is mustard. Just use some extra flux or scrape the top a bit if its oxidised or dirty

AliExpress is showing this product no longer available.

Tested the jaxman connector in my Opus and Liitokala charger and did not see resistance go up

(from AliExpress Android)
Nice thingy
But after testing the inside of my S70 and L6 tube I know the anodization is good and it is not conducting
So I choose magnet for connecting and when charging I put the magnet on the top cell before putting it in the charger so it becomes the bottom one and every charge their position changes (idk if it makes a difference it just feels good to do it like this)

I looked at the link you put,but it is a mess there.The prices differ 50% between them.Which are good and which not.

I decided to use non-protected batteries that can be used in series; there are quite a few to choose from that have a positive terminal suitable for vertical series connection.

I use the Liitokala batteries in my single cell 26650 flashlights.

Or you can get them where I get mine………… RIGHT HERE . Never a problem so far with 3 separate orders.

That Jaxman connector works great by the way……. :+1:

I look at the alphanumeric writings on these batteries,and I see that there are not the same in different sites.Do you know if some of them are better than others?

I had no problem ordering the batteries either, what I tried to write is that the Jaxman ‘connector’ is no longer available from AliExprees. :slight_smile:

My bad, I read it wrong. :person_facepalming:
Hopefully they will come up again, they do work real good. :wink:

Probably all the same.
I got all of mine at GearBest for right around $20 US for four of them and they all check out above advertised specs. :+1:

The LiitoKala 26650-50As can also be gotten at Banggood for a similar steal than at GearBest if you are wise to check out M4D M4X's deals.

Cheers ^:)

P.S.: in fact it becomes a slightly better deal, especially with 3+ units volume discounts.
