Five charging levels include analyzing, charging, conditioning, energysaving auto maintenance, and auto-reconditioning for long-term storage, and the system cycles the batteries monthly to exercise them.

BATTERY TYPE SELECTION: Select battery type for the entire field of banks using one of three plugs that, when installed, set the programming to flooded cell, AGM or gel.

DISPLAY: LED readouts are intuitive and clearly indicate which of the five charge states are active. LEDs also indicate fault status, representing a failed connection or battery. Battery type selection is via a programming cap for AGM or wet-cell batteries.

WE LIKE: The forced induction cooling that employs many cooling fins and a concealed waterproof fan, allowing cooler operations that enable faster charge times.

WE WISH: It had app interface connectivity for added information output and dashboard readouts.

OPTIONS: Remote charge status indicator with 12-foot cable reads charging, conditioning and maintenance modes at a glance.
