Flying with Li-Ion batteries

[Pearlman]

I am planning to buy two dive lights, one for video and one regular. The torch uses two 18650 batteries. I plan to keep one spare set. Which means flying international with 6 batteries each 3.7v at above 2000mAh. Is this allowed in cabin baggage or will I face a problem at the Airport?

Thanks

Must take them in your carry on bag.. Not a problem... Technically you're suppose to put tape on the terminals, but I've never been pulled aside for that..
