Default Is a higher voltage battery ok?

Would it be safe to use a 8.4V 5000 MAH battery in my Exceed Drift Car that comes stock with a 1800 7.2 ?
Thank you

I would think if your ESC runs at 7.2 and you put a battery with an output higher than this, you may run the risk of burning it out or doing damage in some shape or form. Your instructions should specify the range your ESC can handle so its worth checking that out.

You would think the instructions would, but they are abysmal. 75% of the manual is on starting the (nitro) engine for the first time...and other nitro issues. Needless to say, this is not entirely useful considering I have an electric car. I think they included the manual to properly weight balance the packing box.

You don't provide enough info to accurately determine. As stated it depends what type/model motor and ESC are in it. Usually the motors can handle higher voltages but the ESC can not. If it's a 27T 540 motor I have seen info where some have run a 3-cell lipo 11.1volts on it.
With the two packs you mention the voltage off the charger would be around 8.4 volts on the 7.2 and around 9.8 volts on the 8.4.

It would be worth while contacting your LHS, if they are a half decent store they should be able to explain what batteries are suitable for what ESC's and explain why too..

I run a 13.5t brushless sensored motor that can handle a range of powers but my ECS is limited to 7.4, so I run it with a 4250 Overlander 2S 30c 7.4 battery pack... the only difference the larger batteries make is running time, and if you match your battery with the ESCmotor capabilties you would get a 30-45 mins running depending on motor type/set up and car type.
