Fixed PX4/PX4-Autopilot#15986

Do you have any idea that why old 3.5.6 version can‘t load these new BATn_* parameters? Thanks!

It can't. The firmware syncs BAT1_* params to BAT_ behind the scenes.

Oh, can't, right, sorry, typo.
So, new firmware can't compatible on battery settings/messages with old QGC? It didn't syncs BAT_* params to BAT1_* backwards.

It didn't syncs BAT_* params to BAT1_* backwards.

I believe there is still a bug on that in firmware which was fixed here: PX4/PX4-Autopilot#15985.

Stable should be able to sort of work with single battery setup if the firmware parameter sync stuff works correctly. It is missing setup for BAT1_SOURCE though so in reality not so sure if that causes a problem.
