Sony US18650VTC5A 18650 Battery

The Sony US18650VTC5A cell is best 18650 battery cells with 20A-30A Max. continuous discharge current and come with over current protection when cell temperature excees 80'C degree. At 10A discharge 300cycles offical capacity rate more then 1750mAh, this is exceptional good cycle life. 

"The Sony VTC5 (official model number Sony US18650VTC5) is a 2600mAh cell 20A high drain 18650 battery, with a unique specification that sometimes allows usage to 30A.  Sometimes it's labeled as the Sony VCT5 (or US18650VCT5).   Some refer to it as a Konion cell.  It has a great reputation particularly among hobbyists who need high mAh and high drain capabilities like e-bike builders, vaping users, and high powered light customers.

"The Sony datasheet for the VTC5A shows a "Continuous Maximum Discharge Current" rating of 35A. But this is only if the battery temperature is kept at 80°C or lower! This means that 35A is not the continuous discharge rating as the VTC5 cannot complete a 35A discharge without going way over 80°C. There are some VTC5A test results online and they show a good 20A battery that gets quite hot by 25A. I think the VTC5A is just a tweaking of the VTC5 and will share most of its characteristics, including the VTC5's 20A continuous current rating. "  (by Mooch, e-cigarette-forum) 

"The upgrade from VTC5 to VTC5A did not add more capacity to the cell, but the voltage is slightly higher when drawing current. As usual the Sony cells are very good. " (lygte-info)
