Any way to test if my device will handle over voltage or will I just need to wire it and hope for the best?
I want to use a lithium polymer battery in a controller I have, but I do not know if it can handle the voltage difference. It uses two AA batteries (3V) and I want to put a 3.7V lipo battery. Is there any way to test if my device will be ok with it or will I just need to wire it and hope for the best? Thanks.
Davetech was successful in replacing the 2 AA's with a li ion battery here:

I want to be able to test, before I fry my device. Any help will be appreciated. Thanks

If it takes less than 1A to run it, just stick a 1N4001 or similar 1A diode in series with the battery - it will drop 0.7 V for you

Thanks for your input.
It is for a wii remote. I have no idea how many amps it takes to run it. Sorry for asking more of you, but how can I find out?

Its going to be a lot less than 1A, don't worry, use the diode.
