I'm not familiar with those
coils but I would presume so, on the 100% VG question. They seem geared towards that kind of
vaping style.
Bypass mode sort of replicates the experience you'd get with an unregulated device ("mech mod"). The wattage setting is "bypassed" and instead the device simply delivers raw battery voltage (roughly 3.3-4.2v depending on charge state, for a single-battery device; with dual-cells and up, I've seen them that output both combined voltage, and average voltage, depending on the model) to the atomizer. My guess is it would be a little underpowered for those
coils, unless you've got one with dual cells that combines the voltages.
