I had read that info on the ezonemag.com (rcgroups.com) message board over a year ago. Several LiPo importers chimed in and said that this was very old information. LiPo development is moving extremely quickly. Due to consumer applications of LiPo batts lots of $$ have been put into their development.
The LiPo packs I am using today to fly my r/c planes are worlds better than the stuff I bought a year ago.
