Generic said:@Diegobg - Nice work! The 2 Amp discharge is putting more stress on the cells, so it looks like they are degrading faster, about 9% loss in capacity, right? Are the cells heating up at all?
Thanks!It is right. For now, the Liitokala NCR18650B cell has lost 10% or so degradation in 300 cycles.On the temperature, perhaps they heat up a little more than in the Opus test at 1Amp, but not much more. I think that in Opus the cells get very hot from the heat generated by Opus itself.
Now I am doing the same test to the cells of Varicore (another Chinese cell). These have degraded very quickly at first, but after 60 cycles they seem to stabilize. I leave you link:https://electrotinker.com/en/analysis/degradation-ncr18650b-varicore/
