Hi,
I have 12 ikea powered blinds installed. The batteries last anywhere from 2 weeks to 3 months. Since I have to use a 8 foot step ladder to reach them, I got fed up charging the batteries and decided to run a cable between 6 of them and connected to a 7.2 volts power supply. I removed the batteries and made sure the power supply had enough power to feed them all at the same time.
So... I started by connecting the first one... fine. Connected the second one... fine.. but then, one of the DIED. I’ve checked the voltage of the power supply and it was about 7.4 volts. The battery itself shows a voltage just over 8 volts so I assumed I was ok. I guess not.
Not sure what went wrong. But I’m scare trying other things. I can’t afford to blow out another one. I’m wondering if the power supply was wrong, or if one’s noise can affect the others...
Any idea what I can do?
