Replaced the WFCO converter today with a Progressive Dynamics PD9270

This is a 70 AMP converter with the remote pendant that allows you to manually switch between storage, normal charge, and boost mode if needed.
The WFCO converter never charges my batteries at greater than 13.3 volts, when I turned on the new converter it went right into boost mode at 14.1 volts,which tells me that the WFCO wasn't charging the batteries properly.
