I don't think the battle will be over batteries.
Most of the profit is in the juice, and it's the easiest to claim is "not appoved."
You might be looking at $30 or more for 30ml of "approved" juice. Worse yet, I've seen discussion that 8mg/ml juice is about like a cigarette, so maybe that's all they'd approve.
I'd sure like to see a discussion of if it's possible to make nic juice last 5 or 10 years.
Meanwhile, boycott NJOY !
