i run 2S lipo's. but i still also run nimh and even nicd's from yesteryear.
the thing about the older chemistry is dat u can charge them and keep them in the charged state. just peak it before use for 5-10min tops to get max power.
lipo, u cant leave them fully charged or they start puffing up.. so very inconvenient during the weeknights when i just want to motor my rc car around the track a few times..
