25C 5000 Neu vs 35C 8400 Maxamps

So i was able to compare the 25C 2S neuenergy 5000 packs vs the 35C 2S 8400 Maxamps today on the track. Interestingly punch was very similar in the MMM 8Xl powered Emax 18/68. Yes run times were longer on the 8400's - about 45 mins vs 30 mins however what surprised me was that the neu packs got pretty warm - 120 vs 85 for the maxamps packs.
MA may have something with these new packs.
I had puffed several of their 8000 25C packs and had a warranty so they sent me the 8400's and they are a completely different animal. Yes they are expensive but i wanted to share my experience on my track today.
