After the Portable Antenna Expo I have been on a autodidactic quest of which battery (power source) would be best, especially for traveling by air. Any and all constructive comments to help me in the journey down this rabbit trail will be appreciated.?

I would love to hear what did work for you, as well as, what did not work so good. Rationales for your choice is important to me as it helps me understand the overall system more completely.?

I have Yaesu FT 991. I am considering a different radio that would weight less, and as dummy proof as the 991. What radio would you recommend?

I used Dakota Lithium 10 AH 12v batteries for my air travel.? They meet the TSA requirements as long as you keep them in a carry-on bag.

I have the same radio you do. ?I use the Bioenno Power, ,Lithium Iron Phosphate Battery, 12V 20Ah, 240 Watt-hours, P/N BLF-1220A (PVC pack). ?20A max continuous discharge current, 40 Amp max pack discharge current. ?As far as what batteries can be transported on the airlines, go to EACH airline's battery regulations. ?For the most part they are close to the same but each has a bugaboo. ?It's not as restrictive as one would fear. ?That's why so many hams can travel with all their gear AND battery. ?So if you use a particular airline regularly, look up their regulations. ?My battery is big and heavy. ?There are lighter, lower V/Ah batteries available by Bioenno. ?Make sure whatever you get is Lithium IRON Phosphate, not Lithium Ion.
