[RE-wrenches] paralleling amp hour meters on one shunt?

[Larry Crutcher]

Todd,

The shunt is only providing a mV DC signal. In our showroom we have a  
working display wall of charge controllers and battery monitors (Blue  
Sky, Trimetric, Morningstar, analog meters) with a single shunt to a  
single battery. Works well for us. More than likely there is isolation  
before the AD converter so I would not expect any problems with any  
monitor.

Prescaler may be a different story although I suspect it will work. It  
is just converting a high voltage reference to a low one that the  
battery monitor can accept. If there was an issue I would try a small  
DC-DC device at the prescaler outputs going to each monitor.
