Sony VTC5 2600mah

The VTC 5 is a solid 2600mah 18650 20A Cell. It has a higher capacity traded for a slightly lower amperage. 

Mooch's Bottom Line

A good 20A cell that delivers good capacity at an average temperature, but do not exceed 20A. The Samsung 25R delivers a bit more capacity to 3.2V though and runs slightly cooler.
