Displacement category: ≤ 150cc

Displacement range: 150–600 cc

Displacement category: > 600cc

• Wide-temperature-range adaptability: It can operate reliably in temperatures ranging from -40°C to 80°C, enduring both extreme cold and scorching heat, making it ideal for year-round cycling.
• Strong instantaneous explosiveness: Supports 30C burst discharge, delivering instant power; on high-displacement motorcycles, it fires up with a single twist of the throttle, with smooth, responsive acceleration.
• High-rate charge–discharge performance: The 10C charge–discharge capacity retention rate reaches 95%, and a 30C high‑current discharge can be completed in just 15 seconds.
• Full vehicle model compatibility: Covering 16 models across the board, from small scooters to large-displacement heavy motorcycles, with highly compatible installation.
• High-Level Security Protection: Under extreme conditions such as overdischarge, crushing, and puncture, it does not burn, ignite, or explode. Safe and reliable.
• Ultra-long cycle life: Maintenance-free design, lower long-term operating costs, saving you both time and money.
• 0V Deep-Discharge Recovery: It supports auto start-stop even in a deeply discharged state, and can handle voltages as low as 0 V; once charged, it immediately resumes normal operation.

• Winter Cycling in High-Altitude Cold Regions: In the low-temperature conditions of northern winters, conventional lead-acid batteries often fail to start due to insufficient cold‑start performance. This product, however, maintains a robust starting current even at –40°C.
• Replacement of batteries in older vehicles: To address the issues of short motorcycle battery life and frequent maintenance, we offer a maintenance-free, long‑life solution that delivers peace of mind for years after a single installation.
• High-end heavy motorcycle power supply: High-displacement motorcycles demand substantial starting current; this product delivers a 30C surge of instant power, meeting the instantaneous start-up requirements of heavy-duty bikes.

The Fengri motorcycle sodium‑ion starter series employs cutting‑edge sodium‑ion battery technology, enabling charge and discharge through the insertion and extraction of sodium ions between the positive and negative electrodes. Compared with conventional lead‑acid batteries, sodium‑ion batteries offer the following key advantages:

• Excellent low-temperature performance: Sodium-ion electrolytes exhibit superior conductivity at low temperatures, significantly reducing internal resistance and enhancing cold-start performance.
• Fast charging, fast discharging: Supports high‑rate charge and discharge, with high energy conversion efficiency and fast response.
• High safety factor: Sodium salts exhibit stable chemical properties and an extremely low risk of thermal runaway, fundamentally eliminating the potential for fire and explosion.

1. Power outage preparation: Turn off the motorcycle’s power switch and ensure the vehicle is in the off state.
2. Remove the old battery: First disconnect the negative (black/minus) cable, then disconnect the positive (red/plus) cable, and remove the old battery.
3. Install the new battery: Insert the Fengri sodium‑ion starter battery into the battery compartment and ensure it is securely and evenly positioned.
4. Connection Line: First connect the positive terminal (red/positive), then the negative terminal (black/negative), ensuring that the terminals are securely fastened and free of looseness.
5. Test Start: Turn on the power, attempt to start the engine, and verify that the instrument panel displays correctly and the lights illuminate.

This product features a maintenance-free design; under normal operating conditions, no electrolyte addition or special maintenance is required. To ensure optimal performance, we recommend following the guidelines below:

• Long-term parking: If the motorcycle is parked for an extended period (more than one month), it is recommended to disconnect the battery’s negative terminal, or periodically start the vehicle and run it for at least 15 minutes to recharge the battery.
• Charging recommendations: Simply charge the battery using the vehicle’s built-in rectifier. If the battery is deeply discharged, use a dedicated charger to replenish its charge.
• Cleaning Inspection: Regularly clean dust from the battery surface and inspect the terminal connections for corrosion or looseness.

• Short circuits are strictly prohibited: Do not use metal tools to simultaneously touch the positive and negative terminals, as this may cause a short circuit and damage the device.
• Fire and puncture resistance: Although this product offers extremely high safety, it should still be kept away from sources of ignition and protected from puncture by sharp objects.
• Waste Recycling: Please dispose of used batteries through a professional recycling facility; do not discard them indiscriminately to avoid environmental contamination.
• Keep children away: Please keep the battery out of reach of children.
