The PS5 battery has a plug, if the Steam Controller is like that (probably is), the only tool required is a screwdriver, which seems like a great tradeoff to replace the battery every 5+ years instead of every week or two, and being able to recharge it easily and quickly.
Worst case scenario you have to use a generic battery that is about the right size instead of a perfect fit. Maybe a little less battery life but it’s still more than enough anyway.

Use the OS battery charge limiter (or Magisk “ACC” module). Most phones have the capability to bypass the battery and draw from the adapter. Keep it cool and at 60%, and it won’t get spicy. Heat, cycles, and high/low voltages kill batteries, so by avoiding all of those they’ll stay unspicy.
