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.

i actually have a question as well, i came across a 320amp 7.2 volt to 16 volt esc, and im still trying to find a 16 volt rc car motor, but wouldnt this work? i traded a subwoofer for a 1/10 scale hps flying fish drift car. i have a goal of 40 mph in a year, is this possible?

im not a electronics wizard but i would suggest looking at how many volts ur esc can handel, if it cant handel 8.4 KABLOM followed by smoke and maybe a fire. and u may want to look into a heat shield

go ahead and gt a lipo your better off with it and your truck will be faster

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 battery now will last about 15 min. at top speed, it wont exceed 60 seconds at a time, but i do push it il go full speed for a few seconds(20-30 sec) slow to make a turn and what not then return to full speed. thats the part im worried about i race this against my friends nitro truck (our trucks are evenly matched lol). I used a radar and it was registering between 45-50 on a full charge if that helps.

the 3000ma rating measures capacity, not the output amperage

yes, i know that, but its the volts that kills and i need to know if im gunna fry something or melt the 75a speed controller.
