CHEAP NEW ORIGINAL 18650 21700 BATTERY CELLS, POUCHES AND PACKS

Yeah lets keep this to our self. He has been giving us good prices - no need for us to act up and risk prices going up.
 
Present supplier know my prices so is no difference.

I will have soon capacity tests Sanyo Ga under 3A and under 6A continuous discharge after 300 cycles.

I thought I had a massage with a happy ending.

------------------------------------------

Tumich, are you bringing to the market some lower capacity or higher discharge cells?
Be nice to get an ultra cheap cell in the 2Ah, low discharge (5A) arena as an option, seems to be a linear cost analysis though.
 
What kind of cell holder are used in the picture below? Seems much more space saving then those regular Aliexpress cell holders.
Are there some kind of special nickel strips also used? The first pic is from this thread, very first post made of tumich

There are nickel strips which works as fuse in case of short circuit.

Overseas can take 8-12 weeks if shipping by sea. Some freight companies have a rather strange tracking service....you can't see anything with the tracking number while package is underway, maybe just where package was accepted. Kind of like you have seen here. Then suddenly shipping companies truck is in your driveway. That has happen to me several times, mostly from China though.

Check with the sender, maybe he can get more detailed tracking? Or if he calls up the company they can check to see what ship the battery is onboard.

tumich, do you send by air? Which carrier can do it?
Click to expand...

I don't send by air due to regulations. DHL offer that option but not many cells in parcel. TNT and Fedex too but shipping cost is higher than value of cells.

No thats perfectly normal. Should be about 2 months, 2.5 I'd start to worry. Fast Tech took 2 months.
 
Finally, just got an update. It seems that 50-60 days to USA is the normal amount of time from other users here. The shipment started on the 19th of November.

I should get them in a few days.

Doesn't matter anyway because I have no frame yet :( .

Has anyone tested the capacity of these cells?

How much capacity is expected to be lost with these compared to brand new cells?
 
AFAIK these are brand new cells. Should be whatever test of similar cells shows.
 
Just got a message from a forum member that the cells are about 5-6% less capacity when comparing them to the rated capacity and what other people got when testing for capacity.

Can some people here who bought new cells run them from 4.2 to 2.5 volts one cycle to test for capacity. Make sure you top the cell off at 4.2 volts before started test.

It could be that the testing method used by the person who messaged me was not accurate also.
 
Unlikely that "forum member". Was able to replicate the testing method or conditions of the manufacturer.

Hello,
I have 18650 Li-ion cells for sell, they are BRAND NEW, LEGAL, ORYGINAL, NEVER USED
All cells are brand new and have nominal, fabrical voltage ~3,6V or ~3,7V
Li-Ion cells are the most safest, lighter and more life cycles up to 2-3x than LiPO.
The cells are in oryginal boxes.

The full capacity of cell are when you discharge under low voltage (producer made capacity tests under 0,1A), you have then 100% that will have 100% or LITTLE MORE.
If you have for example cell with 10A max discharge rate and somebody tested them under 10A for sure it won't have 100% :D
 
Hey Tumich
Just wondering...the prices you have are great, but will they go down any further any time soon? I only ask because they have been at the current level for some time now.

Cheers
