Can I use a 3.8v battery in a drone that uses a 3.7v battery? Will it also help increase the flight time with the increase in the voltage?

Will the increase in the voltage of the battery fry the esc, or will the battery work as normal.

    I suspect the battery will work as normal, since it needs to somewhat tolerant of differences in batteries.  You cannot tell if the voltage will extend the flying time because you need to know the amp-minutes each battery will deliver to compare them.

    0.1V MORE MAKES NO DIFFERENCE AT ALL !

    AS THE 3.7V BATTERY IS FULLY CHARGED, ITS TOP VOLTAGE CAN GET UP TO 4.2V !!!

    It's probably the exact same battery, just a different seller trying to make them look "more powerful".

    The amp-hour (or milliamp-hour) capacity is what sets the run time or flight time.

    Lithium cells have a working voltage range from 4.2V fully charged down to near 3V when empty.

    3.7 or 3.8 is a nominal "around half charge" type figure.

    Some power tool manufacturers call a three cell battery "10.8V", others call a battery with exactly the same three cells "12V". It's just different points in the charge-discharge voltage range.

    eg.

    3.8 v is within 5% so it will work. If you look at the Data Sheet for your system  it will tell you the maximum voltage.

    The battery will  be okay. Anyway,  the voltage is likely to drop  as soon as you put the battery on load, in other words,  make the drone do something.
