I am going to use ezosd and current sensor,4s 6500mah lipo. I would like to land the aircraft when 80% of the pack capacity remains (1300mah remains or 5200mah is used) and the voltage is 3.7 per cell or 14.8 v in total. The manual is a bit vague for me.
1-Should I set Low Batt Alarm to 14.8v and the Pack Capacity Alarm to 5200mah? Or I should set the Low Batt Alarm to 3.7v and the Pack Capacity to 6500?
2-I see that mah consumed indicator on the screen starts from zero. Should I know how much mah is remaining in lipo before each flight so that I can calculate the live remaining mah during the flight?
Help please.

The mAh reading is only what goes through the CS. It will only read what has been consumed, from every time you connect up the power. So, if you fly for a little bit, then land, and disconnect, when you re-connect, the mAh reading will be back to zero. So, either make a note of your mAh consumed, before you disconnect power, or else, start with a full pack every time, and fly for your 80%

Set your Low Batt Alarm to total pack voltage reading, not individual cell reading. Plus, in your Low Batt Alarm, allow for your Line Loss Voltage (loaded compared to unloaded), and take that away from 14.8v

Have you not got these figures the wrong way round?? 80% remaining is 5200mah

Thank you for your comments. My post was more than a year old. Sorry I did not update it since then. As you mentioned I learned that EZOSD refers to consumed mah. Also 80% consumed was what I ment.
