Hi,

Regarding the first charge of a new LiPo battery:

As mentioned by the manufacturers of batteries Nominal voltage of a battery Lipo is 3.7-3.8 V.
The discharge curve of the battery will probably be exponential with different levels of currents along the discharge therefore does not allow us to work with the shear stress (Vmin - for the specified battery 3.0V if I'm not mistaken) battery when we in flight as the voltage will not be a straight linear (or near linear) to have more control of when the discharge approaches the final voltage of the battery. (probably from what I have seen is the shear stress of 3.0 V per cell .)
But for cycling with charger would be interesting to work your entire spectrum of discharge with a current up to a little less than 1C causing the disposal of electrons for the entire working range is homogenized in the plates, therefore making a test of their performance and reliability (check this good)? .......... believe that this type of procedure can be done to verify exponential amortized or fast cutting when approaching the final voltage (tensção cutting) with a controlled temperature not to shake the very molecules.
This procedure is used in general? What is the main reason you're using the battery is almost to its rated voltage? Curved or straight after this abrupt discharge voltage function of the high current consumption and low voltage required to power?
