The answer may have been a bit late, but if this happens to you, I would fix the problem by doing a simple circuit as a solution. I put one switch between the on and off switch, when the on and off switches are pressed, the switch is pressed in the middle switch at the same time, one end of the switch is on the plus of the battery and the other end is on the control card. It will be connected to the plus input, that is, when we press the switch, the battery will go to the power control card, when the switches are not pressed, the battery will be idle and power will not be consumed.
