- Battery charger with overcharge protection at [url removed, login to view] / cell (cut of current & maintain voltage)

- 3 mode switch :

- Step 1 : 3 set series LED array ON

- Step 2 : all LED ON

- Step 3 : OFF

IMPORTANT NOTE: The size of the circuit should be very small & compact, BUT RELIABILITY should be a PRIORITY
