Conclusions: 1) The labelling at 600mAh is JUST acceptable. These cells do deliver 600mAh to a 3V cutoff at a very small 100mA load. The red line. This is about as generous a test as you can do but they do just scrape in. 2) In practical terms they are really a 500mAh cell. At a 1.5Amp load which is a 2.5C rate for a nominal 600mAh cell they have dropped to 3.35V at the 500mAh discharge point. The blue line. 3) They are fairly described as a 5C rate cell, not 25C as on the label. The green line. At 3 Amp continuous discharge they have dropped to 3.5V at 200mAh discharge and barely 3.2V at 500mAh discharge. Allowing for some small voltage drop in the test leads I would be prepared to call these cells 5C - that is 3Amp maximum discharge.

  • Laurie Verygood analysis, jj604. So the C rating is fictitious. However, I have found that if your requirement is for a modest current, less than 3A, these batteries are quite adequate. I have used them numerous times with my Mini Wing Dragon, and in that application they are as good as any others I have used.

  • BG175433841 I totally can confirm your findings. My Qx95 draws up to 8A which drops voltage to below 2.5 volt which is not enough to keep it airborne. Discarded the cells in favor of some more expensive tattu cells.
