I did a brief search and couldn't find a good answer, looking for some ideas to look into. Currently have mine on a sigelei 75w which would be fine if it didn't automatically turn it down to 50w as soon as the battery hits 80%. I'm hoping to find a mod that's dual battery with a charging slot on the device, and that doesn't do stupid stuff like auto adjust my wattage. So far the istick 100w looks to be the best candidate. Opinions?
