I’ve had one installed for two seasons. The battery monitor function in the first season wasn’t great, but since they released new firmware it has been vastly improved. The tank monitor functions and ammeters
work very well too.
The N2K functionality keeps getting pushed out. They promise that it’s coming soon, but they just move the date out each time.
I use it to monitor a
single bank. I’m a little doubtful how well it would
work (with a
single device) monitoring two banks as it uses a single negative connection, rather than separate negative connections for each bank. Obviously, that negative connection should only be connected to the negative bus (in this case a battery terminal) in one place or else the smoke might escape. So, with say a house bank and an
engine bank and a significant potential difference between the negative terminals on the two banks (for example, while
charging from an
alternator with a small voltage drop to the starter bank and a larger voltage drop to the typically more distant house bank), if the negative connection is made to the negative terminal of the house bank then the reading for the starting bank will be in error.
