How long does a charge hold up on the itaste vv at 1.2 ohms? I recently started to rebuild my kanger attys to 1.8 ohms and I noticed that my itaste vv drains quite a bit faster than at 2.2 ohms. The yellow light comes on within 1.5 ml of juice being used from my mini protank 2. Because of this, I have started to use my MVP at work.
