When I went to pick up milk tonight at the grocery store they actually had a V2 express kit, so I bought it to try it out. Now I will know how long the carts last for me and battery before I dive in and pay for the bigger starter kit. Bonus is I will have two batteries now if I buy that starter kit. I want to say thank you to everyone who helped me out! I will probably ask more questions along the way if I decide to go a different route than the V2 kit.
