I am currently vaping on a Freemax Marvos S using a Brunhilde MTL tank with a .93 ohm coil and the battery is an AWT 3.7 volt High drain 18650. The Marvos S has 3 power options, Power, Smart and bypass. My question is in bypass mode the mod is reading 4.0 volts at 15 watts is this stressing the battery?
