Charging current/voltage for lipo batteries
At the battery terminals it is 4.2 V less voltage drop in the wiring, ie. 4.2 - (0.1 Ω * 0.5 A) = 4.15 V. As the battery continues to charge the voltage difference between charger and battery reduces, which causes the current to taper off. If left on charge for long
batteries
As you discharge the capacitor, the charge on the capacitor is reduced, and so the voltage reduces. However this has nothing to do with batteries. A battery terminal voltage will drop as you discharge it, mainly because the chemical reactions slow down due to depletion.
