Serum,

Austin didn't even come close to suggesting anything like exchanging the packs. As I said above, he said that I just shouldn't worry about it. I don't know why I keep feeling the inner compulsion to continue buying from Maxamps, but I do. I'm going to give the 5Ah cells a try. The 4Ah cells in a 2P configuration make my buggy too heavy for my taste. Our track is on the tecnical side and the extra weight makes the buggy harder to handle. Even the 6Ah packs were a bit big for my taste.

As far as exchanging the packs goes, I don't think I can in any event. Both of the 6Ah packs that I have suffered some damage as a result of crashes and the battery hold downs not doing their job. Boy, R&D is expensive.

What I'll probably do this time is just order some bare cells. That way I can assemble them myself and if I have a problem, I can just replace cells. Working on the welded packs is a PITA, when you have to do repairs.
