Yes but

• it doesn’t let me charge and play at the same time
• I could hot swap in and out batteries, but it doesn’t report battery percentage
• It also doesn’t auto-pause when the battery dies, like other systems do
• It runs through them quickly
• it acts finicky/unpredictable when the battery is very low, rather than reaching a consistent threshold and stopping working
• In combination with a bug/anti-feature I’ve posted about previously, my Steam Deck sees it as a new controller every time the batteries are replaced, despite the Bluetooth MAC/BDA not changing.
