Serious but slightly off-track (actually on racetrack) question.
Over at the RX8 Forum there is a guy who used 4 LiFePo4's to make a lightweight car battery as weight is critical for racing.
Here is the link:
Noting that they are LiFePo rather than LiPo's is this a good idea or a bad idea? Porsche now offers a lightweight racing battery for $1,700 if you were wondering how serious this.
Thanks for the input,
