Pre-Charge Resistor for ASI BAC Controllers

Protect your controller. Prevent costly damage.

The Pre-Charge Resistor for ASI BAC Controllers is a critical upgrade for high-power eMoto setups, designed to safely limit inrush current and protect your controller during startup.

Without a proper pre-charge system, high-output batteries can send a surge of current into the controller, leading to premature wear or failure of internal components.

⚡ Why You Need It

When powering on your bike, the controller’s capacitors draw a sudden surge of current.

This inrush current can damage sensitive electronics if not properly managed.

The pre-charge resistor:

• Gradually charges the controller capacitors
• Reduces electrical stress
• Improves long-term reliability

🔧 Key Features

• Inrush Current Protection – prevents damaging power spikes
• Controller Safety Upgrade – helps extend controller lifespan
• Designed for ASI BAC Controllers – proper compatibility with high-power setups
• Essential for High Output Batteries – required for upgraded builds
• Compact & Effective – simple but critical electrical component

🗒️ Fitment

• ASI BAC controllers
• Compatible with high-performance eMoto electrical systems

🛠️ Installation Notes

• Installed inline with your system power circuit
• Used when the circuit breaker is in the open position
• Proper wiring knowledge recommended
• Professional installation strongly recommended (electrical component)

⚠️ Important Info

• Pre-charging is required for high-power controller setups
• Running without one may lead to premature controller failure
• Recommended based on ASI technical guidelines
