Just sold my power cell batteries so I can go lipo, and I need your guy's feedback. I found an 2s 8200 Mah Lipo battery that I can pair up to use in my Summit. HOWEVER, it says it will fit into a stock Slash 2wd! I want to know how many races I could do on one battery (they are 8 to 10 minutes long and about 3 a day), and how long it would last run time. Need to know cause I will be buying in a couple days. Here is link to batt.
