ARCO Zeus Alternator Shield

The ARCO Zeus Alternator Shield is engineered to protect high-output alternators
from damaging voltage spikes caused by sudden battery disconnect events. These
events, commonly triggered by LiFePo4 battery BMS shutdowns or accidental switch
interruptions, can instantly destroy alternator diodes.

The Shield clamps excess voltage and safely diverts it to ground, helping extend alternator
life and prevent costly failures.

KEY BENEFITS
• Protects Against Voltage Spikes - Prevents damage caused by battery disconnects and
load dump events*
• Designed for Modern Electrical Systems - Ideal for LiFePo4 battery systems with BMS
shutoff risk
• Extends Alternator Life - Reduces stress on diodes and internal components
• Real-Time Status Indication - LED indicator provides instant health status
• Easy Installation - Installs directly at alternator terminals in minutes
• Built for High Output Systems - Engineered to perform with today’s high-amperage
alternators
