Vapcell INR18350 850mAh (Red) 2019

Official specifications:

Model: INR18350 850mah 10A
Size: 18.2*35.1mm
Nominal voltage: 3.60V
End-of-charge voltage: 4.20V
End-of-discharge Voltage: 2.5V
Typical Capacity: 850mAh (0.2C discharge)
Min capacity: 750mAh (0.2C discharge)
Weight: Max: 25g
Internal resistance: Max:27mOhm AC 1kHz
Standard Charge: 500mA, CCCV 100mA cut-off
Quick Charge Current: 1500mA
Max Continuous Discharge Current: 10A

This is high current 18650 LiIon batteries from Vapcell

The two cells matches nicely and can deliver the rated 10A

Conclusion

This is a good quality high current cell with a fair amount of capacity.

Lovely tiny beasts!
Thanks for the test!

I found that they performed better than any other 18350 battery at 25A continuous current.

What kind of setup do you use to test 25A discharge current?

Your graph shows that even at 20A discharge current, it still achieved around 800mAh capacity, even though with a lot of voltage sag.

Also, I wonder how it would perform against the Aspire 18350s. HKJ test is up to 10A, so it is not possible to compare above that, but I would like to see it in comparison :+1:

I use a BK Precision 8601

torchythebatteryboy reported that he requested 25A.
What performance it will have is something else.

If an electronic circuit stops discharging at 3.0 Volts, then it is natural that it does not work if I request such an intensity (Amps) discharge, due to a voltage drop below the operating limit of the circuit.
