This is the only chart I can find so far, if someone wants to translate. The caption is below but unconfirmed.DJI says you cannot safely use Mini 3 Pro or Mini 4 Pro batteries in the Mini 5 Pro. Voltages are slightly different and even though it will launch, it will throw low power errors during flight that can lead to forced landings. Not good.

"Note that mini 5 pro batteries are not reverse compatible with mini3/4. DJI also notes that mini3/4 batteries are smaller than mini 5’s, thus you should expect shorter flight time if you do so."
