I have seen many forum threads out there where someone wants a lower voltage than their battery supplies, and people on the forum suggest tapping into the balance connector to use fewer cells. I have an example right now-- I'm running a 4s battery but need to power a 12V transmitter, so I could just tap into 3 cells.
Seems to me that by discharging the cells unevenly I risk damaging the battery. Is that so? If I balance it after flying each time will everything be OK?
