Works on Swift Go - SFG14-41

[faultypointer]

I have an Acer Swift Go - SFG14-41 running NixOS and I can confirm that charging caps at 80 when health mode is set to 1.
I haven't tested the calibration mode tho.

OS: NixOS 26.05 (Yarara) x86_64
Host: Swift SFG14-41 (V1.14)
Kernel: Linux 6.19.11

Adding these to configuration.nix was all it took.

  boot.kernelModules = [
    "acer-wmi-battery"
  ];
  boot.extraModulePackages = [ pkgs.linuxPackages_latest.acer-wmi-battery ];
  boot.extraModprobeConfig = ''
    options acer-wmi-battery enable_health_mode=1
  '';
