A new 2600mAh battery from Xtar, this time it is called 18650, instead of 18700. This does not mean it is 5 mm shorter, it is only about about 1 mm shorter.
This is very nice discharge curves with good tracking and full capacity at any current.
The current limit is just above 6A. Remember that it will be lower with continuous load.
It looks like a very good battery.
