ofna crome top is a great box! will turn over anything! It is teh best bang for the buck. The only other starter box is the ofna truggy box buts thats 100 dollars. Yes you can run them off 2 7.2v batteries. I sent you a pm! Starter boxi s way better then pull start. They arent as much of a hassel and they will last longer. If you spend moeny on a decent motor it will last 10+ gallons but with a cheap motor your lucky to get 3.
