Default Can't find a specific battery, need help!!!

I'm looking for a 1200 11.1v 20c battery for an electric, but can't seem to find one anywhere. By chance would a 1300 7.4v 25c battery work? I know it probably wouldn't but I thought I'd ask. Thanks!

Correction, I have a 1300 7.4v 20c battery. Just wondering if that would substitute. Or if anyone knows of a place to find the 1200

If you need a 3s battery you don't want to use a 2s to replace it. Here is a 3s 1300mah which would be fine if it fits the battery compartment. They come with different connectors too, I just picked this one at random.

Wouldn't the 30c be too much if it requires a 20c? Or does it not matter too much>

The 30c means the battery is able to deliver a higher max amps if the power system will pull more.

1300ma x 20c = 26 amps max
1300ma x 30c = 39 amps max

Now if your electronic setup can only handle 30 amps and you have too big a prop that is trying to pull 35 amps then the 20c battery is limiting it to 26 amps, which would heat up the battery but the electronics would survive. Now you install a 30c battery, and now the system is able to pull 35 amps from the battery, the battery is still happy but the electronics will fry.

It is not the batteries fault,it is the improper power setup.
