Safe Battery Usage - Percentage, Voltage

[maqeelr]

Hi All,

I am having two batteries with my P3A. Both of them I am using till 40% because I am afraid if I will use less than that then it will damage the battery or reduce the life.

Can anyone tell me what should be the battery percentage to land it and what should be the voltages where I shall consider it to land.

Im seeing this kind of pattern for each cell voltage for healthy battery with 100% capacity:



100.00% 4.2-4.28
90 4.13
80 4.06
70 3.99
60 3.92
50 3.85
40 3.78
30 3.71
20 3.64
10 3.57

At which percentage normally you landed you bird? at 10% or more?

Do not allow any of the battery cells to drop below 3.3V. See more details here.

I start landing when I get to 30%. I'm not a risk taker.

How many minutes of flight time is left at 30%?

Same here. Im normally on the ground at 28-30 percent. Yields about 15-17 mins but i have a 15 cycle battery at 100 percent life.

May be 5-7 minutes, I don't care.

I was just curious, sounds about right to me. I will also land at 30% to start with...

I also land at 30%. More to do with landing safely rather than battery life. I have 4 batteries and always rotate them evenly. Always store at 50% or less.
