[Elecraft] Internal Impedance of Li-Ion Battery Packs

[Walter Underwood]

Batteries are probably the #1 topics on the Summits on the Air (SOTA) mailing lists. The consensus is that the LiFePo4 packs are the best if you can afford them. For lithium-ion, the cheapest reliable packs seem to be from Hobby King.

Li-ion packs are touchy. At least one person charges theirs outside with a bucket of sand nearby. There are several sources for fire-retardent bags for storing or charging those batteries.

There are a few SOTA activators who carry an FT-897 and bigger batteries.
