30A Continuous BMS with 60A Peak Burst
The battery features a stated 30A continuous BMS with up to 60A peak burst capability.
The Battery Management System helps monitor and protect the lithium-ion battery pack during operation.
BMS functions can include:
Overcharge protection
Over-discharge protection
Over-current protection
Short-circuit protection
Cell balancing
Battery monitoring
The 60A peak rating is a burst capability and should not be treated as a continuous operating rating.
Your controller's current requirements must be compatible with the battery and BMS.
Smart Cell Balancing
The battery is equipped with smart cell balancing designed to help maintain balanced voltage among the battery cells.
Proper cell balancing is important for maintaining battery performance and helping the battery operate within its intended voltage range.
Hailong Downtube Battery Design
The AOAE battery uses a Hailong-style downtube enclosure designed for compatible frame-mounted installations.
The stated case dimensions are approximately:
360 × 90 × 110 mm
The battery mounts within the frame area, providing a clean integrated appearance while keeping the battery positioned low on the bicycle.
Before ordering, verify:
Battery case dimensions
Mounting rail
Frame clearance
Mounting-hole spacing
Battery connectors
Connector polarity
Cable routing
Battery removal clearance
Compatible with Bafang Mid-Drive Systems
The battery is marketed for compatible Bafang mid-drive systems including:
Bafang BBS01
Bafang BBS02
Bafang BBS03
Bafang BBSHD
It is also listed for compatible hub-motor and conversion applications ranging from approximately 250W to 1,000W.
Motor wattage alone does not determine battery compatibility. The motor, controller, battery voltage, BMS current rating, connectors, and wiring must all be compatible.
Battery Capacity: 20Ah vs. 30Ah
Choosing between 20Ah and 30Ah depends primarily on how much energy you need and how much battery capacity your frame can accommodate.
20Ah Battery
A good option when you want a balance between battery capacity, size, and weight.
30Ah Battery
Provides approximately 50% more amp-hour capacity than a 20Ah battery at the same voltage.
This can provide substantially more stored energy, although the actual range depends on the complete eBike system and riding conditions.
Battery Energy Guide
Configuration Nominal Energy 36V 20Ah 720Wh 36V 30Ah 1,080Wh 48V 20Ah 960Wh 48V 30Ah 1,440Wh 52V 20Ah 1,040Wh 52V 30Ah 1,560Wh Watt-hours (Wh) = nominal voltage × amp-hours (Ah).
Actual usable energy and riding range will vary depending on speed, terrain, rider weight, motor efficiency, controller settings, temperature, tire pressure, and riding style.
Important Voltage Compatibility
Do not select a battery based solely on the motor's wattage.
Your controller must support the battery's complete voltage range.
36V System
Requires a controller designed for a 36V battery and approximately 42V maximum charging voltage.
48V System
Requires a controller designed for a 48V battery and approximately 54.6V maximum charging voltage.
52V System
Requires a controller designed for a 52V battery and approximately 58.8V maximum charging voltage.
A 52V battery should not be connected to a controller that is only rated for a standard 48V system unless the controller manufacturer specifically confirms 52V compatibility.
Charging Requirements
Use a charger specifically matched to the selected battery configuration.
Typical full-charge voltages are:
Battery Full-Charge Voltage 36V 42.0V 48V 54.6V 52V 58.8V Using the wrong charger can damage the battery and create a safety hazard.
Always verify the battery label and charger specifications before charging.
