5s lipo you mean?

I would suggest the SPC lipos, or Zippy lipos from hobby city if you are after something similar to the TrueRc lipos.

Bear in mind though, 8000mah packs are made from 2x 4000mah packs in parallel, so a 5s 8000mah lipo will be absolutely huge; I'd say look at a quality 5s 5000mah pack, which really leaves you with Zippy or Neu Energy:
