A simple Google search, or indeed a search on the Mac App Store, is all that is needed to turn up a solution to your request. While macOS does not offer an in-built ability to configure the battery percentage threshold at which low battery notifications are displayed, an app on the Mac App Store called Battery Medic does offer such a feature.
