Lithium batteries - 3.7 volt

[novab]

I am traveling with two 3.7-volt lithium batteries.  Do leave them in my checked baggage, or do I bring them aboard the plan in my purse?

Hello,

I wish to travel with 13 GoPro camcorders that I professionally use to video horse trial eventing.

I will check-in a tripod but carry on-board the 13 GoPros and their attached Lithium batteries - 11.1volts 2000MaH, as well as a 7 lbs ENG type camcorder.

Any chance I'd able to travel with the above equipment ?

I do not mind applying for the Global Entry process.

Thanks

You have to travel with them in your carry on. If they are loose the contacts must be covered. You are allowed two batteries each wth a max of 160 wH. 

You gave a voltage rating of 3.7 volts output. Look for the capacity in mAh. Divide that mAh by 1,000 and then multiply the result by 3.7, the answer will give you your wH which must not be above 160 mH.
