APV v3 also shares same features with APV V2
1. It can adjust the voltage from 3.0 to 6.0 Volts in .1 volt increments.
It can adjust the wattage from 3.0 to 15 Watts in .5 Watt increments.
2. The APV V3 can fit (1)18650, (2)18350, or (1)18350! All of this without changing the end cap!
We have tested with flat top 18650s and 18350s. Also works with single button top 18650 and 18350s (AW IMR).
We believe that the (2) 18350 configuration would require flat tops.
