RC car batteries 7.2v to higher voltage?

Hi, its me again and i was wondering if you guys could help me. Well i just got this (http://www.nitrorcx.com/brushless-monster-truck.html) electric off road truck and this monster is insanely fast. But i want a bigger battery. In the instructions, it says the trucks input is 7.2 volts up to 16 volts. But thats the problem, my dad and I are skeptical about putting a battery over 7.2 volts in there. I am hoping to get an 8.4 volt battery (http://www.rcsuperstore.com/ProductDetails.asp?ProductCode=VEN15277T&click=2) like this 7 cell one but am still skeptical about even this 1.2 volt jump. Can anybody tell me if anything  will fry, or be perfectly fine.

The increase is only ~17%, if the manual says it'll take 16 you should be good. These things will get a bit hotter, but it's not much different to running the thing at full power for a longer period. How long do you run it at full power (in seconds)?

the 3000ma rating measures capacity, not the output amperage
