You definitely want some solid batteries and a good charger to complete the brushless experience. I like nitro and electric for different reasons. One can not simply replace the other in my collection, they are both awesome in their own rights.

I have had good luck with venom batteries and will probably try thunder power as my next set of lipos. That looks like a nice charger but you may also want to consider the Hitec X4. I havent tried one but it will be my next charger.
