The one thing that worries me about using the DR-UPS40 is that it doesn't have temperature controlled charging like BCMU does. So we would have to set one charging voltage that is static which will be under voltage in the winter and over voltage cooking the batteries in the summer when the box is hot. We don't heat or cool our boxes so I was looking for something with a little more control of the float voltage with the temperature differences we have. I also would like to only use one battery instead of two.
