Hailong Max 36V / 48V / 52V Lithium-Ion E-Bike Battery – 30Ah to 50Ah

Upgrade your electric ride with a Hailong-style lithium-ion battery from ChargeMyEBike.com. Designed for compatible electric bicycles and electric scooters, this replacement battery is offered in multiple voltage and capacity configurations to suit different power requirements.

Choose from 36V, 48V, or 52V options, with advertised capacities ranging from 30Ah to 50Ah, depending on the selected configuration. The battery includes a battery management system (BMS) designed to help protect against overcurrent, overdischarge, overload, and short circuits.

Whether you're replacing an existing battery or building a compatible electric bike setup, selecting the correct voltage, capacity, discharge rating, and physical dimensions is essential.

Key Features

  • Multiple Voltage Options: Available in 36V, 48V, and 52V configurations.

  • Multiple Capacity Options: Advertised capacities from 30Ah to 50Ah, depending on voltage and availability.

  • Lithium-Ion Battery Technology: Supplier-listed 18650 lithium-ion cells.

  • Built-In BMS: Battery management and protection functions are advertised by the supplier.

  • High-Current Capability: Supplier specifications list 30A maximum continuous discharge and up to 60A maximum current for the configurations described below. Confirm the actual rating for your selected battery.

  • CC/CV Charging: Uses constant-current/constant-voltage charging.

  • Hailong-Style Design: Intended for compatible electric bike battery mounting systems. Confirm the exact housing and mounting dimensions before ordering.

  • Multiple Applications: Suitable for compatible e-bikes and electric scooters when the battery specifications match the vehicle.

Available Battery Configurations

Battery Option Advertised Capacity Full-Charge Voltage Listed Continuous Discharge Listed Maximum Current
36V 30Ah–50Ah 42V 30A 60A

Choose the Correct Battery Voltage

36V Battery

The 36V option has a listed full-charge voltage of 42V. Choose this configuration only if your motor controller and electrical system are designed for a 36V battery.

48V Battery

The 48V option has a listed full-charge voltage of 54.6V. Verify that your controller supports a 48V nominal battery and that the battery's discharge rating meets your motor's requirements.

52V Battery

The 52V option has a listed full-charge voltage of 58.8V. Your controller must explicitly support a 52V battery system; a controller intended only for 48V operation may not be compatible.

Important: A battery's nominal voltage and full-charge voltage are different. Always use a charger designed for the exact battery chemistry and voltage.

Is This Battery Compatible With Your E-Bike?

Before ordering, verify the following:

  1. Voltage: Match the battery's nominal voltage to your controller's supported voltage.

  2. Capacity: Select an available Ah rating that meets your needs and fits the battery housing.

  3. BMS current rating: Confirm the continuous and peak discharge requirements of your motor and controller.

  4. Physical dimensions: Check the battery's actual length, width, and height against your frame and mounting system.

  5. Connector and polarity: Confirm the discharge connector, wiring, and polarity match your bike.

  6. Charger: Use a compatible lithium-ion charger with the correct output voltage for the selected battery.

  7. Mounting hardware: Confirm whether the required cradle, rail, keys, and mounting accessories are included.

A battery's advertised compatibility with a 500W, 750W, or 1500W motor does not guarantee it will work with every motor or controller of that power rating.

What's Included?

The supplier's listing does not clearly confirm all included accessories. Please verify the package contents before ordering. Do not assume that a charger, mounting cradle, keys, or additional wiring is included unless explicitly listed for the selected option.
