if Lipo's are the industries "old" technology and are due to be replaced by something new in three years time, judging by what I have spent on my Lipo cells in the past two years, I will have to fork out about £150 to see me through the next three years.....
I have sold old my Ni-Mih stuff over the past two years, and bought Lipo chargers for myself and my two children. All of those charges can support this new A123 technology or whatever it's called, so they won't need replacing.
The argument that Lipo is now old technology is not a valid reason to disallow the introduction/adoption of them as a recognised power source for our cars.
