Battery Tests and Battery Reviews — 25R5

Best 18650 battery at 0.2 ohm or 16-21A pulsed loads

Posted by Jonathan Caserta on

One question we get particularly from the e-cig crowd is which battery will show less voltage sag and perform better under pulses at a specific ohm level, for example in a mechanical mod device.  The results are very applicable to someone using a regulated (constant watts) device as well.  So we decided to do a comparison test of the voltage drop under this significant constant resistance load of 0.2 ohms, comparing the Samsung 25R vs Sony VTC4 vs Sony VTC5.
