Hailong E-Bike Battery is a rechargeable lithium battery designed for compatible electric bicycles and e-bike conversion systems. The supplied specifications list 36V and 48V voltage options with capacities from 10Ah to 20Ah, making the battery available in several configurations for different power requirements. Energy ratings include 360Wh for 36V 10Ah, 540Wh for 36V 15Ah, 480Wh for 48V 10Ah, and 960Wh for 48V 20Ah. The battery is specified for compatible 200W–2000W e-bike systems and uses a 4-pin holder plug. Built-in BMS protection is listed for short circuit, over-current, overheat, over-charge, and over-discharge conditions. The compact Hailong-style battery format is designed for practical installation on compatible electric bicycles.

Depending on the selected voltage and capacity, the supplied information specifies either a 30A or 40A BMS and continuous discharge current. The battery also includes a button-operated indicator with LED levels showing approximately 100%, 75%, 50%, or 25% charge status. The listed charge temperature range is -20°C to 55°C, while the discharge temperature range is -20°C to 65°C. The supplier describes the cells as Lithium-Ion and separately lists Lithium Iron Phosphate (LiFePO4) under chemical composition, so users should confirm the exact chemistry of their selected configuration before purchase. Capacity options include 10Ah, 15Ah, and 20Ah, while voltage options include 36V and 48V. Verify voltage, connector, dimensions, motor rating, and charger compatibility before installation.

SHIPPING POLICY

The Shipment of your products is our highest priority and every day we dispatch hundreds of products to satisfied customers across the world. 
However, because the majority of our warehouses are in Asia, our shipping and handling times can vary and we are therefore unable to offer next day delivery.

Processing Time: As soon as we receive your payment, we immediately dispatch your order to our supplier for order verification, tailoring, quality check and packaging which can take an additional 1-4 days.

Shipping Time: This refers to the time it takes for items to be shipped from our warehouse to the destination. For CANADA / US-Based deliveries we use E-Packet which is a US postal service product which typically takes 15-21 days. For other international deliveries, the shipping time may vary.

Tracking: As soon as your order is shipped, you will receive a confirmation email containing a tracking number allowing you to easily locate your product directly from our website at any time (www.MokeruProfessional.com).
