I can think of a couple reasons why they don't:
- 2s packs are cheaper for companies to send for testing.
- A lot of racers, especially 1/10 scale, use 2s packs. Many people won't make the connection that if a 2s pack performs well, then a 4/5s pack made of the same cells will perform just as well. Gotta remember that many people are fairly new and/or not knowledgable about how these things work.
Also, "field" testing 4s and 5s packs should be easy enough, but bench testing becomes problematic. To get 100A+ out of a 4s or 5s pack is going to generate a considerable amount of heat. And components that can handle that aren't cheap. 2s is far easier power-wise. 7.4v at 150A is "only" 1,110W, but 18.5v @ 150A =
2,775W!
