Test/Review of Efest IMR18650 2600mAh (Purple) 2016
Efest IMR18650 2600mAh (Purple) 2016
Official specifications:
Very nice curve, the batteries match perfectly and the capacity is fairly stable up to 20A. These curves are made with my new 4 terminal rig, this means the voltage at high current discharge will be higher than in the old test. I do also expect better matching between curves at high current (With good cells), because connection resistance is not included anymore. How hot do the cells get during discharge? I have added a termo sensor to my test stations and will show temperature traces for high current discharges. They will only show the temperature raise, not the absolute temperature, the actual cell temperature is 25° to 30°C higher. If the cell gets too hot I will stop the discharge to avoid melting my battery holder. The temperature sensor will always be a bit behind the real battery temperature. Here the cell gets to hot a few seconds before it is empty and I terminate the test (It is automatic). Conclusion The battery has very good performance, but it gets very hot at 30A. Notes and links The batteries was supplied by Efest for a review. Improvements to test stations How is the test done and how to read the charts How is a protected LiIon battery constructed More about button top and flat top batteries Compare to 18650 and other batteries
