What happens if my battery is below the recommended C level for my plane?

Hi, so i just brought the tundra V2 and a 2200 mAh battery to go with it but its has 25c. Ive only just noticed that in the description of the tundra requirements it wants a 30c battery. What would be the issue of having a 25c battery instead of a 30c battery? or would i still be okay with a 25c battery.
