don't see much racing LiFe's because racers cant be giving up .4v per cell + extra weight. I'm about to move over from NiMH to LiFe for my bashers, LiFe are perfect for bashers - more cycle life, safer, faster charging, and the batteries themselves are harder to damage and less volatile when they are damaged.. etc etc

i'm putting 2300s 2s2p (and maybe 3s2p) in a hpi e-firestorm, and 2s1p in a brushless mini-t. If all goes well i'll be converting my whole stable over.. nimhs to life's do not pass go and do not collect lithium polymer.. oh and eneloop nimhs for my tx
