Test/Review of Efest IMR18650 3000mAh (Purple) 2016
Efest IMR18650 3000mAh (Purple) 2016
Official specifications:
High capacity and high current cell. The cell is very good up to 20A, but at 30A I terminate the test due to temperature. The tracking between the cells shows that they are very well matched. Temperature raise at 15A load, to get the real cell temperature add (about) 25°C to the temperature. I had to stop here, my rig melts at this temperature (I hope to improve this). This is also the maximum discharge temperature for the battery. Conclusion The battery has very good performance, 20A is no problem, at 30A it is probably best not to use continious discharge. Notes and links 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
