Description

NIU MQI+ / UQIGT / UQI+ / SQI Extended Range and Performance Fast Charging Battery – 48V (85–160KM Range)

Increase the range and overall performance of your NIU scooter with a high-capacity battery upgrade.

• Range anxiety limits longer trips
• Frequent charging becomes inconvenient
• Limited performance from the original battery

This battery upgrade increases total range and allows multi-day riding without frequent charging.

What makes our battery cells different?

This battery is built using large-format lithium cells used in high-end electric vehicles. Compared to traditional 18650 cells, fewer individual cells are required, resulting in fewer weld points and improved long-term reliability.

• Aluminium casing per cell for improved safety compared to soft pouch cells
• Lightweight with higher capacity compared to lead-acid batteries
• Fewer cells required → fewer weld points → longer lifecycle
• More stable performance under load

The battery is tested before shipping to ensure proper fitment and operation.

Features

• Increased range due to higher ampere capacity
• High-performance BMS (80A line / 200A phase current)
• Bluetooth BMS app for real-time monitoring
• Digital display (battery %, voltage, amp output)
• Reinforced casing (waterproof, rust-proof)
• Plug-and-play installation — retains original functions

Compatibility & Installation

Designed for NIU MQI+ / UQIGT / UQI+ / SQI models (48V systems). The battery is plug-and-play and works with original components.

For dual battery scooters (such as MQI GT), both batteries must be upgraded to avoid imbalance issues.

Upgrades & Performance

This battery increases range and provides a slight performance improvement.

• For maximum performance → combine with a controller upgrade
• For extended range → use with a dual battery setup
• For higher performance setups → consider upgrading to 72V

How to estimate range

1. Compare original vs upgraded battery capacity (Ah)
2. Example: 53Ah / 20Ah = ~2.6× more range

Charging

You can use your original charger. Charging time increases with battery size.

Example: 53Ah battery ÷ 4A charger = ~13 hours
Using a 10A fast charger = ~5 hours

Production & Shipping

• Production time: ~1 week
• Delivery time: 2–3 weeks
• Import duties prepaid for most countries
