How would you rate this battery?
Just finished testing this battery pack. This is NOT a dualsky pack...I would like to see how you guys would rate this battery. I will give you a hint, it is over 10C rated discharge.
I have displayed the 1C test as a baseline and did as high as I could without exceeding the limits of the battery. The next lines are 10, 12, 14, and 15C. I will post the identity of the cell next Sunday! |

The graph implicitly "rates" it, e.d.
C "ratings" should be abandoned, IMO. - RD |

From the graphs, it looks to me like a 2-cell 830mah 12C battery. Fairly solid 3.5V per cell at 10C, and 3.4V per cell at 12C. Very unstable voltage curve at 14C and total crap-out at 15C.

Pretty close guess to what the manufacturer wanted

Run a few more 14C tests, then run a 1C follow-up test, as that is the truly meaningful result. If you have capacity loss between the first 1C discharge and the last, you're pushing the cell too hard. Almost all Li-Po's will give one good "abused" result, and then it's downhill from there! |

I agree..that was the second 14C run! I will be setting up for some more tests..

I'd rate that as a 10-12C cell.
For decent life, anyway. |
