The 500 mA maximum charge current sets the ceiling for single-cell charging — for a typical 1000 mAh cell, that's a 0.5C rate, keeping charge times reasonable without stressing the cell. The 20-VFQFN Exposed Pad package (3.5x4.5 mm) helps conduct heat to the board copper pour.
No — this device is designed for single-cell Li-Ion/Polymer batteries only, with a battery pack voltage of 4.2 V.
