I don't think that is a meaningful measurement. With no battery connected, there will be no feedback to the charge controller.i did not plug in the battery when doing this measurement cause i would like to see how much voltage is it passing to charge the battery
Most batteries put out slightly higher than their rated voltage when fully charged. In the case of "3.7v" LiPoly cells, the full charge voltage is 4.2.I remember seeing a post about the charging will stop at 4.2V, does it means that if the LiPoly battery is only 3.7V it will just kept on charging and will not stop drawing power?
