I don't use any of those batteries listed. I am using LI-FE batteries, the A123 batteries. I sold all my nimh batteries about 4 months ago, except for the AA rechargeables I am using in my transmitter. I use the A123s to race, 2S1P packs and I am allowed to use them in the stock class here too! I use a 3S1P pack in my rock crawler, and I plan on throwing in a 5S2P pack in my custom e-maxx/4-link brushless monster truck.
