[QUOTE="Texas Gonzo, post: 19671, member: 3142"] When balance charging, as the spark charger does, each cell is being charged individually at <5v. That 12~13v input is actually being divided by 3, along with the input amperage by the charge controller. A 3 cell lipo is full at 12.6 total volts, with 4.2v per cell. Setup properly, one could technically charge a 3 cell battery with a 5v input, not 12~13v necessarily. That input would also need to be around 1.5 amps however, to supply each cell a 500mA charge rate. Now, obviously the chargers for say, the Phantom3 line DO charge at ~13v *in series* since they only have a 2 pronged connection. Balancing those cells is accomplished by the smart battery itself, internally. Jus' sayin' :-) [/QUOTE]
