This battery uses a unusual construction with the protection mounted at the + pole. The maximum current from this battery is not very high, probably due to the unusual protection placement.
Protection trip current is to low to show in the chart.
This battery uses a very good cell and is one of the shortest 3100mAh protected batteries, but due to the low current limit it will not work in all lights (The problem is XM-L lights).
