Modern marine electrical systems put greater demands on charging systems than ever before. Larger battery banks, new battery technologies, and more powerful inverters all place an extraordinary load on your alternator -- making it more important than ever to provide optimal charge control.

"Smart"; Multi-Stage Regulators
Our most advanced charge controllers to date! The Max Charge MC-612 automatically monitors battery conditions and uses up to a dozen individual time and voltage values to optimize battery charging. Enhanced by an all-new 3-digit numeric display, the digital MC-612 makes it easier than ever to monitor a wealth of operational, programming and self-diagnostic info. Selectable programs for six battery types, as well as user programmability make the Max Charge as simple or as precise as you choose. The Max Charge also provides manual equalization, amp manager, automatic conditioning and exercise programs to maintain battery health. The Max Charge monitors and compensates for alternator and battery temperatures when equipped with optional temperature sensors. Dual battery temperature sensor inputs allow monitoring of two batteries. The MC-624 provides the same advanced charge regulation for 24-volt charging systems.

Use the ARS-4 right out of the box, or tailor this multi-step regulator to guide your Deep Cycle FLA, Optima, Gel or AGM batteries through bulk, absorption and float modes. Easy-to-read LEDs indicate program mode, battery type and provide for self-diagnostics. Connections for warning light/alarm and electrical tachometer are standard.

Single-Stage Regulators

The BRS-2 Regulator offers simple, single-stage regulation that is easy to install and easy to use. Factory-set 13.7VDC can be adjusted for a range of battery types. Includes inputs for IDIOT light and electrical tach connection. The BRS-2-24 is available for single stage, 24VDC regulation.

The economy ERS regulator provides a non-adjustable 14.1-volt field to the alternator, making it an ideal, inexpensive back-up charge controller for most battery types. Its built-in wiring and small size allow convenient storage in your toolbox or "spares" locker. Built-in mounting tabs allow the ERS to be connected directly to the back of the alternator. The ERS-P is included with BALMAR Series 81 and 812 alternators.
