What are the best Li-Po batteries to get for the Ken Block? I am purchasing one next week and plan to buy everything at once. I don't want to go really fast just something around 30 to 40 mph and have some fun. I was thinking about either of these:

Traxxas 11.1V 3300mAh 3 Cell 25C 1/10 LiPo Battery 2846 $52.00

Venom 15038 30C 11.1V 3200mAh 3S LiPo Hard case $49.99

What do ya'll think? What is the best charger to use also?

Thanks for the replies.
