Hey guys I am having problems with my starter box and I am going to be picking up a new one. One thing I needed too ask is the what lipo amp rating do you think is needed too run the two 775 motors on 4s?

This is the box. I am getting something cheap with a low capacity (around 2000-3000 mah). Probably a zippy. Also what balancer if any is needed for a duratrax ice? I am hoping too order today. Thanks
