You can also lower the wattage on your mod. Less power, less juice consumption. Right now, I have my baby beast on my 200 watt Kbox, but I'm only running it at 40 watts. I do the same for my Cloud beast and baby beast coils that are the octo .15 ohm, I run them at somewhat lower wattages. This helps some, and you can tweak it to where it will work best for you.
