A high current 18650 battery. According to specifications I got from AWT the 30A are pulse rating and 15A is continuous rating.
The batteries cannot deliver 30A. The batteries has about the same capacity, but there is a difference in internal resistance.
The battery can deliver a lot of current, but the difference in internal resistance means that it is a bad idea to use them in series especially at high current.
