All, I am still waiting for my PFC-20 and my new PFC-30. EdT, can you send me info the MSDOS controlled PFC charger again. I couldn't locate your old email. Thanks. Also, I have decided that it might be best to test the full system on my Sparrow. In this case, I will pay for the cells, which are roughly $10k for now. Since my recent decision to leave my day job, I would have much more time running detailed experiments on them. Also, I met another electrical engineer who is also trying to convert his car using LiIon batteries. He is pretty concerned on safety and he found this company that claims to have safe LiIon batteries. Can you guys take a look and post who you think about it? Thanks. The video is kind of interesting. It does make me think about safety issues that we might be facing. http://www.valence.com/saphion.asp http://www.valence.com/SafetyVideo.asp Ed Ang
