  • Capacity drops to 2780mAh at 2.80V for 5A and 10A.
  • Capacity drops to roughly 2610mAh at 2.80V for 15A and 20A.
  • Six cycles at 20A showed almost no loss in performance, indicating that the cell wasn't being badly overstressed. But, there was about a 1% loss in capacity by the 6th discharge. I don't know how this will translate into actual cycle life. A 10A discharge done after this showed less than 1% loss of capacity.
  • Four cycles at 25A did not show any drop in voltage-under-load but there was a 2.5% loss in capacity between the first and fourth 25A discharge. The overall voltage drop at 25A was significant and the cell got too hot to recommend a CDR higher than 20A.
  • A 10A discharge done after this showed a 2% loss in capacity at 10A. Not much on its own but it does indicate that slow damage is being done at 25A.
  • Cell temperatures at 20A are comparable to other cells, indicating that cycle life at 20A should be similar.
