Keeppower has two types of 18500 batteries, this is the best one, it is based on a Sanyo cell. The other is based on a DLG cell.










The battery can handle up to 5A, but has a large voltage drop when doing that. The rating of 3.4A (2C) looks very resonable.
The over current protection prevent drawing 7A for longer time.
