This is a simple rechargeable lamp:

The Lipo will come with a suitable USB charger. Use this and switch the battery either to the charger or to the LED via a current limiting resistor. The resistor should limit the LED current to 20mA.

The charger supplied with the Lipo should take care of everything, it provides over-voltage protection, under-voltage protection, pre-charge and charge at a current appropriate to your chosen battery. Have a look at this to make sure you understand Lipo charging:

Construction should be on a vero board or similar.
