Note quite what you're use case is, but if you're looking to have something permanently plugged-in without risk (or, at least microscopic risk) of battery swelling/fire, recent models of Samsung phones+tablets have a "Maximum battery protection" mode where you can limit charging to 80%. I use an old Galaxy S22 as a control panel for the solar+inverter+security systems in my travel trailer - its permanently plugged in and just happily hangs on the wall keeping cool and doing its thing.
