[size=+3]LG 18650 D2 3050mAh (Blue)[/size]
Official specifications:
LG batteries with fairly high capacity, but they are too old (2014) to be high current.
The discharge curves tracks nicely and the batteries can deliver the rated 5.9A, but not much more.
[size=+3]Conclusion[/size]
The batteries are good quality batteries, but cannot match newer chemistries for current.
[size=+3]Notes and links[/size]
Vapcell told me that I was missing some cells in my comparator and they would be happy to supply them.
