43.8V 25A Lithium Battery Charger

The ARC 43.8V 25A Lithium Battery Charger is designed for in-vehicle and stationary charging applications. It replenishes battery energy efficiently while the vehicle is parked and meets automotive-grade standards for temperature resistance and vibration durability.

⚙️ Key Features

High Efficiency: >90% conversion rate for faster, cooler charging

Wide Operating Temperature: Performs reliably in various environments

Comprehensive Protection: Over-voltage, over-current, reverse polarity, short-circuit, and over-temperature protection

Automotive-Grade Design: Resistant to vibration and impact

Smart Temperature Compensation: Adjusts charging parameters for optimal battery life

100% Full Load Aging Test: Each unit undergoes rigorous reliability testing before shipment

🧱 Installation & Mounting

Mount on non-combustible surfaces (metal, brick, or concrete) only. Ensure at least 3 inches (≈8 cm) of clearance around the cooling fan for adequate ventilation.

Recommended Mounting Orientations:

Horizontally flat with the fan/handle facing upward

Vertically with AC/DC cords facing up or down

Side-mounted with cords facing left or right

Avoid:

Mounting with fan facing downward

⚠️ Safety Precautions

Always connect to a grounded AC outlet.

Do not charge mismatched batteries — only charge the specified type, voltage, and capacity.

Disconnect from AC power after charging.

Keep the charger in a well-ventilated area; avoid sparks, smoking, or open flames near batteries.

Surface temperature may become hot — avoid direct contact.

Only qualified technicians should service or program the charger.
