Default Lipo % remaining capacity vs resting voltage

Is there a accurate chart for lithium polymer for resting voltage vs. remaining capacity? Thanks, I'm new.

Here's all I have seen posted so far and wanted to update and check the accuracy and the bottom numbers as well as interpolate.

4.20 v = 100%
4.03 v = 76%
3.86 v = 52%
3.83 v = 42%
3.79 v = 30%
3.70 v = 11%
3.6? v = 0%

Well look pretty accurate, but it may be different form a brand to another...

I would think that all li-po would be the same, I am looking for a chart that may show a (linear) graph with 10% increments,,,

Here's another thought,,,,I will test a cell and see, but how about a procedure for testing?

first thought is to discharge at a very very slow rate taking hours to discharge and hopefully it will be very close to a "resting voltage" "?: just a thought,,, any other ideas? or existing charts?

Look at the battery Vault.

Thanks still researching, the place I got mine from is stating a minimum of 3 volts for a no-load voltage and others are using a 3.7.

I used 3.5 to keep it simple but wonder if I am even going too low.

U-dUd,
What I've read it is 3 volts loaded. Great graphs aren't they.

Yep, it seems that 3 volts loaeded is agreed (the load is not agreed however) but the resting voltage seems to be in great disagreement.

I am all "graphed out" I find it hard even to keep mine all organised so I can understand them, what a mess,,,
