---

Designed for Compatible Bafang Motors

The product listing identifies this battery for Bafang motors from 250W to 1500W.

Compatible applications can include different Bafang hub and mid-drive configurations, depending on the motor voltage and controller.

Before ordering, verify:

• Motor voltage

• Controller voltage

• Controller current

• Battery connector

• Battery mounting system

• BMS requirements

Motor wattage alone does not determine battery compatibility.

---

30A Battery Management System

This Hailong battery is specified with a 30A Battery Management System (BMS).

The BMS helps monitor battery operation and protects against conditions such as:

• Overcharging

• Over-discharging

• Excess current

• Short circuits

• Cell imbalance

The 30A specification should not automatically be interpreted as the battery's continuous safe discharge current under every operating condition. Confirm the manufacturer's detailed BMS specifications for your selected configuration.

---

18650 Lithium-Ion Cells

The battery uses 18650 lithium-ion cells.

18650 cells are widely used in rechargeable battery packs for electric bicycles and other electric mobility applications.

The overall performance of the battery depends on the cell configuration, cell quality, BMS, current requirements, temperature, and battery construction.

---

Cold-Resistant Battery Design

The supplied specifications list a discharge temperature range of:

-20°C to 65°C

This specification refers to discharge operation.

Charging lithium-ion batteries at extremely low temperatures can require different limits. Always follow the manufacturer's recommended charging-temperature range.

---

1,500+ Cycle Life

The manufacturer's specifications list a cycle life of 1,500+ cycles.

Actual battery service life depends on:

• Depth of discharge

• Charging frequency

• Charging temperature

• Storage conditions

• Discharge current

• Battery maintenance

• Cell aging

Proper charging and storage can help extend battery life.

---

2A Charging Current

The supplied specifications list a 2A charging current.

Charging time depends on the selected battery capacity.

A larger-capacity battery will generally require more time to charge at the same charging current.

Use only a charger specifically matched to the selected battery voltage and charging requirements.

---

Hailong Battery Dimensions

367mm × 110mm × 90mm

Before ordering, compare these dimensions with your existing battery and frame.

Make sure there is enough space for:

• Battery case

• Mounting rail

• Charging port

• Discharge connector

• Wiring

• Frame clearance

• Battery removal
