    Tp4056 connection issue

    I have 2 tp4056 to charge and 2 18650 cell, so i have connected both the charger in parallel with the cell so that it will charge both the cells seperately, i wanna drive an 5v led display with the output from each tp4056 connected in series with a 5v voltage regulator to pull the voltage down. So can i connect the output of both the tp4056 in series.

    it wont work - you would need 2 seperate psu's for the tp4056 chips that are isolated from each other.
    use a module designed to charge multiple cells like a TP5100
