Sony VTC5A 2500mAh 18650 Bench Test Results...a fantastic 25A battery!
Bottom Line: The Sony VTC5A is a top-performing 25A 2500mAh battery. It runs at a higher voltage than the Aspire 1800mAh, VTC4/5, 25R, and HD2C and runs for almost as long as the VTC5. I want to do some more comparisons against other cells but this is probably one of the top three best 18650's.
