Suppose I am trying to boost the voltage of my 3.7V Lipo battery to 8V using a boost converter (MT3608 module) and lighting up some LEDs.
Does the voltage of the battery reduce just because of the boosting circuit, if no load is connected at the output(which is 8V) of boost converter?
Does the boosting module play a role in reducing the battery voltage when no load connected, or does the battery drain as usual in the same way with or without a boosting circuit when no load is connected?
I'm doing it practically now. My lipo battery voltage is 3.7V, I boosted the voltage to 8V (without any load) and left it to check whether boosting circuit reduces the batery voltage. In 1 hour battery voltage has reduced to 3.67
What is the reason for this and how can I avoid this problem, since suppose say if we are trying to make a PCB, Lipo battery will always be connected to boosting circuit and it can drain the battery overnight.
