Samsung high tech 21700 48X 4800mah and 50G 5000mah battery

Batteries and Chargers Rechargeable Batteries

These high-capacity 21700 batteries are commonly used in electric vehicles. It has excellent consistency, high power, high capacity and very high cycle life

In the field of electric vehicle battery, battery quality requirements are very strict. Thousands of batteries are combined into a battery pack, which requires excellent consistency and more than 2000 cycles of cycle life

So the battery rating is very harsh

Samsung 48x and 50g are excellent batteries with similar power performance, which beat Sony VC7, Samsung 50E, Samsung 48g and LG M50

Please refer to discharge curve comparison 15A

In addition, the Samsung 48x has an amazing 3000 cycle life

This is the highest cycle life of cylindrical lithium battery that I have seen so far, which is a happy thing. Lithium battery technology is progressing slowly

sounds great

Where do you get them from?

This 21700 Tesla rewrap also has 15A continuous and slightly higher capacity, and 1500 cycles, should be enough for most BLF’ers.

Dennis - Thanks for the comparison between all these different Samsung cells.

I don’t see any graphs comparing the 48x and 50G. Do you know why Samsung created two models if they have the same performance?

7

Hopefully HKJ gets a pair of each soon.

Please try again

We have sent each pair to HKJ a few days ago :slight_smile:

10

I don’t see the graphs either. Tried a couple browsers and on mobile and no difference.

11

I can see them now.

For the people that cant see them I reuploaded them to imgur:

I had trouble seeing them too, on mobile I could see the non loaded pic icon and open in a new tab and that worked.




edit : thijsco19 mirrored them just before me.

I assume the 48x trades a bit of capacity for cycle life. It would be nice to see the full specs/datasheets.

Thanks you very much，sir :+1:

datasheet is PDF file :person_facepalming:

14

Is the issue file sharing between China and rest of the world ? if so a quick search gave some results : https://nihaocloud.com/ , https://cowtransfer.com/ (I haven’t tested those)

Mooch’s Test of G50

16

Both Samsung 50g and 48x currently come in two colors, gray and green

The figure below shows the complete technical table of 48x

17

Thanks for the tests Dennis.

In the datasheet above, does anyone know why it says “Avoid direct wind” in section 3.1 and 3.2?

On a different note, too bad the datasheet doesn’t specify either the 4.15V -> 3.0V capacity or the cycle life at 4.2V -> 2.5V

Hi Dennis,

Do you have a datasheet of the G50?

19

Thank you very much for your information sharing :wink:
