nimh or lipo or other?

[uncomplientspud]

alright so i have been doing my research and i have many questions, so far you guys have been great. I am doing a flm savage conversions. i was going to either run a 4s lipo set up or maybe 14.4v nimh? Is there something wrong with nimh cells and the load they can put out. What about those a123 cells(is believe that is spelled wrong) What are those cells made of. If someone could provide a link with some reading material that would be great.


If any other help, esc and motor thoughts? thinking of ferigo xl? and that mgm esc that cost about 135?

Thannks for all the help
