39%, at what load?

As batteries age, they may appear to still be good (have a high voltage) but under high load they drop voltage very quickly.

If you're using the CTRE Battery Beak, use the % or voltage at whatever the highest load is (18A?). That should give you a better idea of what it will actually run at during driving.
