How do I reduce a Lithium Polymer battery voltage? Answered
I have a 7.4V lithium polymer battery (http://www.all-battery.com/74volt-6000mahli-polypackwithpcb31185.aspx) and an 8.4V smart charger (http://www.all-battery.com/universalsmartchargerforli-ionpolymerbatterypack37v-148v1-4cells.aspx).
The issue is that I need to power a device that needs 6V. If I put a voltage regulator in line with the battery leads I'm sure it'll work, but then how do I charge the battery with that charger, as the regulator will also reduce the 8.4V the battery needs for charging? Maybe by introducing some kind of "bare metal tap" upstream of the regulator, so when I plug in the charger it bypasses the regulator and wires straight to the battery? (see the attached illustration) Would this work? Or should I do something else?
