    Zeus A275L N62 Alternator with Clutch Pulley & RegulatorThe highest power output alternator in its size/class. Features: Engineered for High Energy Production. Suitable for Marine, RV, Military, and Commercial applications. Rapidly charges large battery banks. Coolest operating temperatures for increased performance. Runs 8 - 20% cooler than incumbent alternators due to:    - Heat shedding coatings   - Rectifier located on housing exterior   - Dual cooling fans   - OEM Components It is optimized for performance at idle speeds. Reduces the need for a generator by creating additional power with your engine. Unleash peak performance with E-Coat/Cerakote. Our advanced coating absorbs less heat, keeping the A275L cooler. This translates to more amperage for sustained periods. Use an ARCO Zeus Bluetooth alternator regulator for maximum performance or lithium battery charging. SAE J1171 Certified. Made in the U.S.A.

    Balmar Digital Duo Charge - 12/24V [DDC-12/24]

    3 in stock

    Digital Duo Charge - 12/24VThe Digital Duo Charge (DDC-12/24) provides a “hands off” solution for charging two battery banks without the use of problematic isolators or manual battery switches. During charging the DDC-12/24 monitors voltage at the house battery. When voltage exceeds the set minimum (typically 13.2V in a 12V system and 26.4V in a 24V system) the DDC-12/24 automatically engages, providing up to 30A charge current to the starting battery. When no charge source is present, the DDC-12/24 separates the batteries so the starting battery won’t be accidentally discharged into the house battery. An optional solenoid control enables higher start battery charging output when required.Features: Multi Bank Charging The DDC is a Solid-State Battery Combiner Control Voltage and Current between House and Start Batteries Eliminates the Need for an Isolator, Relay or Manually Operated Battery Switch Used in Concert with Max Charge or ARS-5 Regulators Can also be Employed without a Balmar Regulator Works in Both 12V and 24V Applications House and Start Batteries can be different technologies Start Battery Temperature Sensing Available with the MC-TS-B Sensor Cable 4 Battery Programs Supported for the Start Battery: Standard Flooded, Deep Cycle Flooded, AGM and Gel Cell This product may not be returned to the original point of purchase.
