Test/review of AW IMR18650 3000mAh (Red) 2016
AW IMR18650 3000mAh (Red) 2016
Official specifications:
Batteries with both high capacity and high current ability from AW. The discharge curves tracks very nicely and capacity drops only a little with increase current, at least up to the rated 20A. But why do one cell terminate on temperature and other do not? From this temperature chart the explanation is clear, I forgot to mount the temperature sensor on the A cell. The battery gets rather warm at 15A The cell without temperature sensor must have been very warm here. It was warm enough to get damaged! The damage to the A cell is very obvious here. And also on this curve. Due to this damage I had to cheat with the "internal resistance" value in the table, it is only for cell B, I did not use the value from the damaged cell. Conclusion The batteries has good performance but watch out for the temperature at high current. Notes and links The batteries was supplied by aw-akku.de for review. 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
