Balmar MaxCharge MC-618-H 12V Multi-Stage Marine Voltage Regulator with Harness

Replaces MC-614-H

SKU: BAL-MC-618-H Category:


Balmar’s new MaxCharge MC-618-H 12 volt marine voltage regulators feature custom-selectable preset programs for nine battery technologies – standard flooded; deep-cycle flooded; gel; AGM; spiral-wound; LiFePO4; and Carbon Foam AGM – plus a default factory safe program and a separate program for vessels with voltage sensitive halogen systems. Advanced programming mode adds even greater user control.

Balmar has upgraded its legendary MC-614 Voltage Regulator to communicate with the SG200 Battery Monitor!  Now you can see how the New MC-618 Regulator is directing your alternator charging activity from either the SG200 2″ Color Display and/or the optional Bluetooth® Smartphone App.  Basic setup functions can be accomplished from the SG200 Color Display, Smartphone App or the traditional on-regulator programming tool.  Advanced Programming functions are available and easily configured from the Bluetooth® Smartphone App.

  1. Andre

    Great voltage regulator with many programmable options to adapt to your boat conditions and battery system. Can be put off remotely which means you could act on the regulator with a Lithium battery BMS.

    Great help and support by Tim to configure the required components. Balmar delivered in St Martin through a forwarder and the installation was done on the boat at anchor !
