On board battery(ies) for powering radios/Flarm etc

Thanks for that link. Price is decent, under a $100 for a 10 amp hour battery. I think I could easily over double that capacity with a couple power tool batteries in the same cubic space, however, the cost would be 4 times that.

LiPo tech has come a Looooooong way in the last 5 years. I cannot recall hearing about a LiPo combusting during use in a long time. Even at the ultra high amp draws I use in my chop saw, the batteries dont even get warm.

I was always anti-battery power tool until my first Milwaukee impact driver/hammer drill set 2 years ago. I have spent the last year renovating my house and upgrading all my tools. I am nearly 100% cordless now. I just had a wild idea that perhaps some of this new battery tech can come the way of soaring. I wasn't sure if anyone else was out there doing it.
