I have a 7.4v LiIon that hold 1450ma. I have a variable DC bench power supply that I can crank up or down and adjust as needed. I want to quickly charge the battery and noticed if I adjust the power supply to 7.4V +- I can only get 150 ma or so current out of the power supply. If push the Volts to7.8 I can get 300 am and the current keeps going up the more I increase the voltage. How far can I push the battery to charge it quickly? Could I use 9vdc to charge a 7.4vdc battery. Note: there is no circuitry unless inside the battery itself. I just attached probes from the supply to the battery. Wish there was an easy way to make a cradle for the different pins on batteries- but that a different topic altogether.
