Description

NIU FQIX Extended-Range 72V Battery

Upgrade from the original system to a 72V battery for substantially more range, stronger acceleration and greater performance potential.

• Extended riding range with 70Ah, 100Ah, 120Ah and 150Ah options
• Higher-voltage performance for compatible programmable controller setups
• Bluetooth BMS for battery percentage, voltage, current and cell monitoring
• 72V charger included

A compatible programmable controller is required. The original charger cannot be used with this 72V battery.

Compatibility and installation

Designed for NIU FQIX models. Contact us with your exact scooter version before ordering so the correct battery configuration can be confirmed.

Installation requirements depend on the selected capacity and scooter configuration. Dimensions are not currently listed; contact us for fitment confirmation.

Battery construction

The battery uses large-format lithium cells with aluminium cell casings. Compared with conventional 18650-cell packs, fewer cells and weld points are required, supporting improved long-term reliability and cycle life.

• High-performance BMS: standard 120A line / 300A phase current
• Optional higher-current BMS configurations are available after consultation
• Each battery is tested before shipping

---

Performance

• Noticeable range and performance improvement with a suitable controller
• Compatible with higher-power motor builds when the controller, wiring and supporting components are matched correctly
• For maximum performance, combine the battery with an upgraded controller and motor

Production and shipping

• Production time: approximately 1 week
• Typical delivery time: 2–4 weeks
• 100Ah, 120Ah and 150Ah batteries ship by sea freight due to their size and hazardous-goods classification
• Import duties are prepaid for most countries

---

Important

• Lithium batteries are classified as hazardous goods
• Structural modification may be required for some capacities and scooter configurations
• Returns are accepted only for shipping damage or functional defects

Before ordering and getting started

How much extra range will I get?
The result depends on the selected battery capacity and how you ride. Send your target range, usual riding speed and current battery capacity so we can recommend an option for your scooter. A range estimate is not a guaranteed distance.

Can I keep my original controller and charger?
This upgrade requires a compatible programmable 72V controller or the model-specific configuration described above. Use the compatible 72V charger included with the battery. The original lower-voltage charger cannot charge this pack.

How do I confirm that it fits?
Send your exact FQiX version, selected battery capacity and compartment photos for fitment confirmation. Dimensions are not listed for this model, so confirm the configuration with us before ordering.

Which BMS option do I need?
Send the controller model and whether you are keeping the original motor or fitting a larger one. We can match the BMS option to that build; a larger capacity alone does not specify the required current.
