Ball being thrown from catcher hits the bat that is above the head of the batter while she is doing these warm up swings. I ruled interference, called batter out, and moved runners back. What do you say?

Since we're speaking FED, the appropriate rule is 7-4-4:

"[The batter is out when] The batter interferes with the catcher's fielding or throwing by leaning over home plate, by stepping out of the batter's box, by making any movement which hinders action at home after the pitch reaches the catcher or the catcher's attempt to play on a runner, or by failing to make a reasonable effort to vacate congested area when there is a throw to home and there is time for the batter to move away."

FED Caseplay 7.4.4.A gives this explanation in a similar play: "B2 is entitled to her position in the batter's box and is not subject to interference unless she moves or re-establishes her position after F2 has received the pitch, which then prevents F2 from attempting to play on a runner."

Essentially, the batter must stay in the box and not move when F2 attempts a play on a runner at third. Any movement, even to reset in the box after the pitch, that hinders the catcher would be grounds for an interference call.
