Tech Note
With a discharged battery, because of the potential difference between the charger and the battery, the recharge current is initially high and tapers off as the battery voltage and SOC increases. This results in the battery being partially recharged quickly, but it requires prolonged charging to obtain a fully charged state.

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 enough the battery will eventually reach 4.20 V when the current drops to zero.
