I second that...After trying some cheap batteris and having swollen packs and others that won't hold a charge I stick with the good quality packs and treat them well. I have some Thunder Power packs that have over 100 flights on them and they are still working fine. I watched a friend of mine try some cheap packs last Sunday in his new P51 and they lost power after less than 2 minutes and he had to ditch his plane as he couldn't make it back to the runway. Did some pretty good damage to the wing and cowl and tore one gear out. If you want to try them on a throw away plane go for it, but be prepared for trouble.
