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

Sweden Post did not work ! 4x18650 were sent back to FT and I was refunded.

My last shipment from FT, a 3-pack of ICR18650-30Bs, arrived home last wednesday with no issues for me; well, no issues albeit maybe the tadly slowboat shipping (a month and a day) compared with a torch I had issued on the same order which took 3 weeks; order shipping was split because of stock issues with the batteries. Both shipments through Sweden Post registered.

Cheers ^:)

I just ordered 2 too I have 2 keep power coming which are exactly double the price will be interesting to compare them

Selling like hot cakes!

In the cart these go!

Cheers ^:)

Received my first pair this afternoon (I have another pair coming), they both arrived showing 3.79v.
I immediately put them in a Lii-500 charger & charged them at 1A, let them rest for 1 hour then performed a discharge test.
Results,
Cell 1, IR during charge 24, IR during discharge 22, capacity 5096.
Cell 2, IR during charge 19, IR during discharge 20, capacity 5176.
Not quite as good results as Mitko, don”t know if that could be due to different chargers, or slight differences in the cells themselves but both of my cells were pretty uniform & still good results none the less ?
Both cells just exceeded stated capacities after 1 initial charge from new :slight_smile:

There have been few posts over here and at CPF that some Opis BT C3100 users found that their chargers overstated the battery capacity when the run discharge test, i.e. the capacity of their batteries (especially 18650) as shown on their Opus can be 100-200 mAh higher than the official rated capacity.
I have never encountered this problem on my Opus, just that this issue are mentioned by some members at both forums

I am performing another charge/discharge test just to see if there is any difference in capacity after a second charge & will post the results later today.

Second charge/discharge cycle finished.
Cell 1, IR during discharge 23, capacity 5114
Cell 2. IR during discharge 18, capacity 5190
So fractionally better than the first test results but still within a few ma”s & the cells seem pretty well matched :slight_smile:

Nice numbers, indeed.

Now, if those IR values are to be believed, that would mean these cells should handle a continuous 20A discharge rate with ease (within a ≈10W thermal envelope).

Grreat!

Cheers ^:)

Darn, I only bought one to play with a week ago. Any left? I know GB will say they have them when in fact they don't. Well, against my better judgement I went ahead and ordered 4 more. I don't expect to see them in any less than 60 days, maybe longer.

What are you discharging them to? 3 volts?

I have another pair coming from another supplier so we will see how they test compared to my first 2.
Might show if there is continuity with these cells :wink:

My other pair of cells from the other supplier have just arrived :slight_smile:
Checked the voltage & both showed 3.79v, exactly the same as the first pair :+1:
I have just started a charge cycle & will report back with charge & discharge results when finished :wink:

Just received 4 pcs of Liitokala 26650 yesterday. Voltage around 3.82 V.
I will do capacity tests on 2 of them in the next days. Tests will be on 1A, 3A and 5A. 7A test is possible on request.

The more current, the better :wink:

Thanks for all the info! What sellers have you bought them from? The first and second pair?

Has to follow this thread. Got 4 from the Ali seller and 4 from Gearbest. Will take weeks before I have them I’m sure off.

Can these be used in series or they are full flat tops?

They can but be advised all: those batteries are kinda not exacly 26mm but like an idea thicker, they barely fit into S70 for instance

As IMR/INR they dont perform well in series with buck drivers- i would reccoment Efest 5200 or Soshine 5500 in this case

First pair were from Aliexpress, second pair from GearBest.
Gearbest”s were much better packed :wink:
They are on discharge now :slight_smile:
