Remaining battery always shows 99%

i’m using apm version 3.3.2 copter with a attopilot 180 amp pm . I have gone though the optional hardware battery voltage and amp calibrations and they show up accurate on the screen but the bat remaining % always shows 99% even when battery may be down to say 70%. I’ve look though the perimeter list and couldn’t find any thing that I could tell that would be causing this to happen . I’m new to this and could use some help. any ideas .

Did you set corrrect battery capacity in parameter ?

yes I have entered the capacity correctly I’ve also tried changing it. same thing 99%

Same issue for me. I hate this 20 character limit crap.

I have this problem. Battery Always 99% regardless the actual charge.
Cant find the solution in this thread.
Anyone knows how ti fix It?
Many thanks
