Need to design a charger circuit for charging a 4V, 1 Amp Lead Acid Battery with the following features: 1. Input is standard smartphone micro-USB charger, hence it must have a female micro-USB input 2. Voltage must be stabilized so that it doesn't damage the battery 3. Auto cutoff when fully charged 4. Soldering terminals for the battery, a switch & an LED (1 Watt SMD LED) 5. Efficient consumption of battery by the LED 6. As light weight as possible The ultimate aim of the circuit is to charge a battery and light up an LED simultaneously. In case of power failure, the battery acts as a backup for the LED. Be advised this LED is not for charging indication.
