[aprssig] Batteries for standalone trackers

[Tim McDonough N9PUZ]

I fly smaller RC airplanes in addition to my Ham Radio hobbies. Hobby 
King has a very similar LiPo pack to the ones listed below at around 
$8.25 each. I have three of them and they work well. They also make nice 
power sources for small QRP rigs.

Quick shipping from their USA warehouse.
