It really depends on the size and shape of the object. The 25kg guideline includes all manner of things like big fridges etc.
Most people can at least pick up 80kg + without injury, we can hoist each other up by the waist for example (the elderly and fat excluded).
What you want to do is make the battery swap use optimal movement patterns. Few people are lifting 50+ kg at a weird angle or above their head for example.
