I also don't see how she can have anything on me simply because someone else has always been around with me and my daughter.

It's entirely possible that she didn't have anything on you -- until you behaved like jackass at her home.

I posted on here for legal advice to help my child. Not myself for the battery stuff or anything.

My advice: if you want to help your child, and it's true that you are the best person to do it, then don't act like an idiot so that you end up losing custody. Act calm, controlled, and rational.

Talk to a lawyer for legal advice.

I'm not here to give you legal advice.

I'm here to give you a little life advice, because it's clear you're not acting in a controlled and reasoned fashion. Here is another shining gem of a quote from you:

I feel that she had them there on purpose to provoke me. She didn't tell me he was there till I arrived and seen him. She told police she texted me that he was there but I have proof she texted me and said it after the police already arrived.

Okay, so it's entirely possible that she manipulated the entire situation to make you look like an ass. But you know what? That's not even illegal. In fact, if you were a custody lawyer, you would even consider that a very cunning and successful move on her part, or just lucky, if it really was unintentional. Who knows?

And you know what? Regardless if it was intentional or not, you completely fell for it. You allowed her, or her situation, to provoke you into an emotional and uncontrolled response to a ridiculous situation, and now a custody evaluator, who will already be hopelessly biased against you as a male, can easily make a case that you lack to emotional maturity and self control to deal with a crying, possibly also manipulative kid.

There are a lot of possible explanations for how you allowed you to happen. One likely explanation has to do with matriarchy. You live in a world where women constantly whine and fret about men being "unwilling to fight for their relationships." You know, the usually feminine whining.

No matter how "romantic" they may make this see, never indulge a woman who expects you to "fight for your relationship." This is simply an avenue for your exploitation, as is plainly evident here. Lesson learned. Cut it out with the white knighting crapola. Be rational, and focus on what matters legally, not emotionally. Find out from your lawyer what that is / would be and stick to that.
