So I'm going on vacation tomorrow and am taking some of my lipo packs with me. The vehicles are already down there. They went with my parents in the trailer. But I needed the packs to run at home before I left.
Im also traveling with my daughter for the first time and was unsure of any regulations regarding strollers and food etc. So while I was checking on that I also stumbled across the following information:
There are a number of links and linkable definitions on that page that will take you to other pages and explain further the details. However, what I learned is this.
-Batteries installed IN a device are acceptable under any circumstance.
-Batteries under 100 watt/hour is considered a "small" battery and is un-restricted. You can carry as many as you like but they MUST be carried in your carry on, NOT in your checked baggage.
-Batteries betwee 100 and 300 watt/hours are considered "larger" batteries and you can only take the one in the device and 2 spares.
The math to find out how many watt/hours your packs have is listed RIGHT on the official government web pages. It specifies that this rating applies to Lithium Polymer packs as well and even states "rc toys" as a use for the batteries.
The equation is MAH/1000Xvoltage = Watt/Hours
Based on this math my 5400mah 2S lipos (for argument sake they will be listed as 7.4 volts as that is what a 2cell LIPO pack is described as) are only 39.96 watt/hours. They fall UNDER the 100watt/hour limit for a "smaller" battery and therefore I can pack as many as I want IN my carry on.
I thought this was interesting as I've read a number of threads here in the ally asking about traveling with Lipos. The websites listed above explain it all in detail and make it pretty clear, traveling with Lipo packs under 100watt hours is completely acceptable.
Just for interest sake, I tried to figure out what lipo pack would be OVER 100watt/hours.
SPC 8200mah 3S pack is only 91 watt/hours
5000mah 4S pack is only 74 watt/hours
5000mah 6S pack is 111 watt hours and would be considered "larger" and therefore you could only travel with 2 spares.
I don't own any batteries that would be considered "larger"...
Thought this was interesting.
