Battery Use Capacity...what does it mean?

Hello,

With the Battery ID/UI sensor installed on my NEO, under battery setup menu, there is a parameter called Battery Use Capacity where you can set the percentage. What is it's purpose? What does it do? If I set the percentage to 70%, what happens when I reach 70%? I haven't noticed anything on my radio indicating that it's time to land.

I've read this http://www.vstabi.info/en/node/1696 and can't find any explanation, only a vague description.

This is how much of the capacity of the battery will be left when the talking telemetry tells you you have 0% of the battery left. So on a 5000 mAh pack if you set this to 20% it will tell you you have 0% left (and give you the alarm you set) when you have consumed 4000 mAh.

Set this to what percent of the total you want left in the pack when you land, and fly until the telemetry tells you the pack is empty.

Thank you. This should be added to the manual.
