Case Ground

Engineered for high energy production.
Suitable for marine, RV, military, and commercial applications.
Rapidly charges large battery banks.
Coolest operating temperatures for increased performance, running 8-20% cooler than incumbent alternators due to:
- Heat shedding coatings
- Rectifier located on housing exterior
- Dual cooling fans
- OEM components
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 A225S cooler for sustained amperage output.
For maximum performance or lithium battery charging, use the ARCO Zeus Bluetooth Alternator Regulator.
