Can coach batteries be monitored by a solar controller not connected to panels?

We plan to get a complete solar system in 1-2 years but canít afford the entire system now. We ruined our 2 golf cart 6Volt batteries by relying on the factory idiot light battery monitor and cigarette lighter voltage meter.
We need to buy new coach batteries and would like to find a better way to monitor the volts, amps and state of charge without purchasing a $300.00 Trimetric battery monitor that we were told we wonít need when we buy the complete system. Does anyone know if a MPPT solar controller can be used to monitor volts, amps, and state of charge of coach batteries without being connected to solar panels? Thanks in advance.

The solar controller can measure the volts but it is not going measure current draw on the batteries. It will only monitor the current from the solar panels charging the batteries.... once you have them installed.

I don't know what type of rig you have but you could consider a Progressive Dynamics Converter / Charger. Many models are less than $250 and it has 4 charging modes to protect the batteries.

Thank you Judge for your response. Which *Progressive Dynamics Converter / Charger would you recommend? Do you have any opinion on a Xantrex converter/charger?
