The Balmar ARS-4 is a high-performance, microprocessor-controlled 12-volt multi-stage smart voltage regulator engineered for recreational marine applications. Designed specifically to maximize the efficiency of high-output marine alternators, the ARS-4 replaces standard, single-stage internal regulators with a dynamic charging profile. It ensures your house and start battery banks are charged rapidly, safely, and to their exact technical specifications, significantly extending overall battery life.
The unit utilizes a multi-stage charging strategy (including Start Delay, Soft Ramp, Bulk, Absorption, and Float stages) to safely drive maximum current into the batteries without overheating them or stressing the engine belts.
