Description

A DC to DC Charger that allows charging one battery bank using another as the power source. It can also convert voltages (e.g., 24V to 12V). Ideal for single voltage vessels with mixed chemistry batteries. The Mac Plus 24/24-50 uses a 24V bank to charge another 24V bank with up to 50A. It can be used in 24V lithium-powered systems, eliminating the need for changing alternators or starter batteries while allowing safe alternator-based charging of a lithium house bank. It supports 3-step+ charging (Bulk, Absorption, Pre-Float, Float, Plus), is compatible with Flooded, Gel, AGM, Lithium, and Custom battery types, and can be paralleled with up to 4 units. It features temperature compensation, silent fan-less operation, and Masterbus or CZone/NMEA 2000 configuration, monitoring, and control. Optional programming via dip switches is available for simplified installation.
