Am I cooked

I have a meepo v5s that I've put about 400 miles on. I took it out earlier today and it was raining a bit.I didn't think too much be they said it was safe to ride in the wet. But then it started beeping but not turning on when i pushed the button. I took it apart to inspect and this is what the battery connectors look like. How bad is this gonna be to fix.
