If it helps, both the E-Power 14650 and the E-Power 18650 feature voltage regulated at 3.7V. You can use a Kick to convert a mechanical
mod (APV) that features only an ON/OFF switch to VV. I don't believe there is any easy way to use use a Kick with a
mod (APV) that already features advanced regulation circuitry.
The E-Power regulated 3.7V keeps output at 3.7 while the battery is charged from 4.2 to 3.7V. Unlike the Kick this voltage regulation circuitry can not boost voltage and has no VV function.
