Notes

Batteries provided for testing by: Basen Group

Basen lists the discharge end voltage as 3.00V and standard charging current as 0.2C, but I have chosen to simplify my tests and prevent procedural mistakes by discharging to 2.8V and charging at 0.5A. This should also make it easier to compare my test results against each other and against other reviews.

The discharge tests at 10A with the Turnigy Reaktor may have up to 20% error. The discharge tests with the Maynuo M9712C should be much more accurate. I have left the 10A graphs created with the Reaktor up to allow comparison.

I started adding a discharge graph that shows watt-hours. This could be useful for those considering different chemistries. I didn't see the value of that graph until I started considering if I should use nimh D batteries for 26650 or 32650 lithium ion batteries for a potential lantern mod project.

The first post has been updated with results from additional test equipment.

  • 10.0A discharge tests with Maynuo M9712C
  • Internal resistance test with SM8124 (4 wire tester)
  • Internal resistance test with Opus BT-C3100 (smart analyzing charger)

I have to say I was surprised that this cell holds more capacity then stated (at least at lower discharge currents).

Thank you for this informative and very detailed test !

btw
I tried to find these cells online, but no luck.
Not that I really wanted to buy a pair, but researches are part of the hobby. :wink:
