A very high current 18500 cell.










The cells are good at high current, but the capacity is not matched.





The temperature raises fast at 20A, but stays at a safe value.















[size=+3]Conclusion[/size]

These cells are good at high current, but due to the capacity difference they are best not to use in series.
As is usual the case with high current cells, the capacity is not in top.
