Test/review of Soshine 32650 6500mAh (Black)

Soshine 32650 6500mAh (Black)







Official specifications:

  • Capacity: 6500mAh

  • Chemistry: Li-ion

  • Voltage: 3.7V

  • Lifespan: More than 1000 times



This is a large (32650) sized LiIon cell with the not that much capacity (This size do not have the best energy density for LiIon).










One of the cells looked like it have been very hot after the test, the other did not.



One of the cells is above 6500mAh the other below.

I have left out the temperature curves, the two cells tracks fairly well on them and do not get hot, but that is not consistent with the heat damage on one of the cells.















Conclusion

The batteries have about the expected capacity for 32650 cells, but the variation between them is way to large.
I have no explanation on why one cell got very hot and the other not.

Thanks HKJ! The variation in capacity is very sad because apart from that they look really good.

Hello, dear master HKJ :sunglasses:
Tell me, please, do you have information about such batteries? After your professional tests, the expected results of these elements can be very interesting for assembling powerful batteries that are used on electric bikes:

I publish all my tests and I do not have more than a few set of test data in queue for publishing. I do not have data for the above cells.
