Hi, I would like to use 2 batteries for my project. They are Li-ion if it matters. I would like to use one to drive the circuit, until it is completely dead, or just about, then switch to the other. But while using that battery I would like the other to be charging.
I was told to use this as a good switching device: Link
But from what I understand is that this only lets you use the one that is at a higher voltage. But I want to have total control over which is being used at what time.
Any other component recommendations or if this one is sufficient maybe someone can help explain it better.
Thanks
