Some of those circuit have to have a true ground connection. They will not work without it. Linear has few chips that act up when your not on real ground.
I do not know about that one in particular. But seeing it 12v - 80v I would not purchase it. You need something that can run as low as 7 volt up 15v. The potential difference closes quick.
I like solid state locking relays but they tend cost a bit for the power they can handle.
But as far as you guys are concerned you can do what your trying to do easily with Arduino.Ada Fruit Metro mini or equivalent, a TLE7231g SPI interfaced, Power distributor.
The Arduino has enough ADC port to read all the batt voltages and based on that you communicate with the power distributor through SPI to make it turn on what ever switch's you need.
If you only have 4 battery positions then you have 4 possible scenerio's. You could even just use pins on the Arduino to control that.
Truly thats pretty small project unless you looking to push more than 100 watt.
But remember you need modulation in the current flow and the total voltage on your load and your charge batt need to exceed the total voltage of the serial batts or your power will just wind down slowly. You'll be reasonably efficient but nothing special. Find what I am telling you, and you'll see months of runtime not days. Its not hard to do, but it hard to do with low voltages.
Later you'll realize batteries are not required.
I was wondering why you guys jumped out of the wood work to help clean things up bit. LOL
