No DANA Multiply by 4.2v max voltage100_0182.jpg
battery / nominal voltage / maximum charge voltage / minimum discharge voltage
1S / 3.7v / 4.2v / 3.2v
2S / 7.4v / 8.4v / 6.4v
3S / 11.1v / 12.6v / 9.6v
4S / 14.8v / 16.8v / 12.8v
5S / 18.5v / 21.0v / 16.0v
6S / 22.2v / 25.2v / 19.2vComment

You are both "right"... 3.7 is nominal... 4.2 is optimum... However, there are almost NO, if any, cells that will be 4.2V under any load at all...
You are better to figure out your setups using 3.7 or 3.8V/cell, and calculate from there. And that would be for GOOD cells... VERY good cells might.... MIGHT, hold 3.9 or 4.0V/cell for a very short period of time at the beginning of the discharge cycle (first 20-30 seconds), but even that is a push...
I do all my "guestimation" using 3.7V/Cell...Darin E. Jordan - Renton, WA

Each cell of a LiPo has a nominal voltage rating of 3,7 Volt and a maximum charge voltage of 4,22 Volt (4,2V is standard).
That means the LiPo is used in a "voltage-window" ranging between 3Volt and 4,2Volt.
In contrary to a normal accumulator the voltage of the LiPo cells will not sink below 3 Volt !.
If a cell is discharged below 3 Volt, this will cause irreparable damages. Afterwards a complete charging is not possible and its shelf life is very short.Attached FilesLast edited by mannytx1; 12-29-2012, 12:18 PM.Comment

you still multiply by 3.7 to figure your rpm'sComment
