With the heat of Florida the neoprene protect the battery from direct sun repelling the x-rays. Again depend in the point of view. Is not for you. I used to fish a lot in Stuart and lived in Port St Lucie for 3 years and 4 in West Palm Beach by the Summit, Next to the Trump Gulf Club.Ok, maybe its not that significant but anything you add adds weight and wrapping a battery increases heat, (especially)
in Florida. My point wasn't about going 1,500 or 3,000 feet, I use strobes also, its that when you go out to fly you check the weather, that includes , what's the wind speeds, how the radar look will it be raining soon and if so, I know it and don't fly.
I live 30 miles north of West Palm, we've had our share of rain this year. Happy flying.
