what are the advantages of li-ion batteries? do you need upgraded FETs to run li-ion? what kind of gains would be seen from using these with a stage 2 RS motor, and would it improve more with the addition of the Si FETs? would i see an improve ment with only the addition of FETs and running 4 cell Ni-MH. What type of motor would you suggest that would be a little more efficient than a RS motor, i don't want anything crazy i race in a basment so 40mph is useless.

thanks in advance
