    Hi All,

    How to get constant power from battery as battery is constantly depleting and it's voltage and current drops out.

    Could you please suggest me schematic for battery connection to get continuous power till the time battery voltage drop to cutoff voltage.

    Looking forward for your help.
    Thanks.

    Look up "voltage regulator." Generally, you will need a battery voltage higher than the circuit operating voltage; although, there are so-called "boost" regulators that provide a voltage higher than the battery is capable of providing.

    Hello John
    Thanks for reply.
    I don't need higher voltage than battery.
    I am looking for circuit which i can use with battery so that once battery is discharging then circuit will boost the power so that output power will be maintained throughout the battery operation. i am using li-ion 3.7V battery.

    Thanks in advance.
