I don't think the problem was your soldering, it was the cells!!
The Energizer aaa's suck for high current. They are not sanyos, they are chinese cells.
only the Energizer AA's are Sanyos, and are Japanese.
In battery manufacture there is always the trade off between high current handling ability and capacity. This is why the 850's put out less current than the 650's (as well as the quality/design).
If you are looking for a really cheap way to power your BCP check this out:

It should be noted that ni-cads in general kick butt on ni-mh for high currents, especially in the cheaper stuff.
have fun!!
R/CNerd,
Thanks for info. I should have checked where the AAA Energizer batteries are made before I solder the pack. I assumed that they are also made in Japan since somewhere I read that Energizer batteries are Sanyo. I just checked the batteries I soldered together for Blade CP previously and confirmed that they are all made in China.
My reply is late because I was too busy to check this forum during last week. I also thank you for the cheap battery back info. Unfortunatley last week I decided to migrate to Lipo and now I am happy with that (was too disappointed with my home made NIMH battery pack with Energixer). But still that is a great deal.
