Lithium Ion Battery Separation for FAA Limit

[BlakeCarmichael]

I am currently looking into Lithium Ion batteries in the 500-1000 Wh range @ 20-40 V, but the problem is that for the application, the ability to carry the product (and battery) on an airplane is a must.

I have recently learned about a battery pack that can easily separate into multiple, smaller capacity batteries that allow it to pass FAA airline limits on carrying Lithium Ion batteries aboard an airplane.
The battery is the Dewalt 20/60 V Flexvolt. It is a 120 Wh battery, which is above the 100 Wh FAA limit on spare batteries. But, the battery has the ability to be changed into three 40 Wh batteries, just by turning a switch. I learned about this technology in this YouTube video from 1:00-2:00 : https://www.youtube.com/watch?v=8b9ZYt6MzHc&t=...

Aside from this YouTube video, I can't find any information on the technology, which brought me to this forum. Dewalt doesn't even seem to advertise it.

Does this exist in any other batteries? If so, any in the range specified? (500-1000 Wh @ 20-40 V)

Thanks!
Blake

Thanks, LiGo looks great.
I would rather have one large battery that could switch, similar to the Dewalt system, but the LiGo style may work just fine. Looks like they are about 75% more expensive than a battery with comparable capacity, though!

Any other companies out there?

I regularly fly domestic commercial with 8-10qty of these 74Wh packs - https://hobbyking.com/en_us/turnigy-5000mah-4s1p-14-8v-20c-hardcase-pack.html

Never had any TSA issue (I'm Pre-Check) and majority of the time they don't even look. I carry them in a Lipo charging Bag with electrical tape over the plugs.

Easily series together to create 12S or 16S for my application.
