Description
The Balmar MC-618 is the latest generation of Balmar's smart, multi-stage Max Charge voltage regulator, developed to deliver precise, battery-specific charging control for Balmar high-output 12-volt alternators and other externally regulated P-type alternators. It replaces the long-serving MC-614 and adds a new Carbon Foam AGM battery profile, improved high-temperature alternator control, and protection that prevents lithium batteries from being charged below freezing. User-selectable programs cover deep cycle flooded, standard flooded, gel, AGM, spiral wound AGM, Carbon Foam and LiFePO4 batteries, plus a universal default program for vessels running voltage-sensitive halogen equipment.
Beyond its preset battery programs, the MC-618 offers a full suite of advanced programming modes so charging can be tuned to almost any installation. It communicates with the Balmar SG200 Battery Monitor over the SmartLink network, letting you view real-time charging stage, target versus actual voltage and field output percentage on the SG200 colour display, and when the optional Bluetooth gateway is added, full basic and advanced programming is available from the Balmar smartphone app. Used with the optional MC-TS-A alternator and MC-TS-B battery temperature sensors, the regulator monitors ambient temperature and reduces or discontinues charging if a catastrophic over-temperature condition occurs. This part number is the regulator only, supplied without a wiring harness.

What alternators does the MC-618 work with?
The MC-618 controls Balmar high-output 12-volt alternators and other externally regulated P-type (positive field) alternators. It is a 12-volt regulator and is not designed for N-type or internally regulated alternators.
Does this part number include a wiring harness?
No. This is the regulator only. If you need the plug-in wiring harness, choose the MC-618-H version, which is supplied with the 54 inch harness.
How is the MC-618 different from the older MC-614?
The MC-618 keeps all the regulation features of the MC-614 and adds SG200 Battery Monitor integration over SmartLink, smartphone app programming through the optional Bluetooth gateway, a new Carbon Foam AGM profile, improved high-temperature alternator control and protection against charging lithium batteries below freezing.
