HSS Energy's 72V 40Ah Electric Motorcycle Lithium Battery is built for OEM and trade customers who need more than a basic commuter pack. The 20S8P 21700 platform combines 40Ah capacity, a removable steel housing and high-discharge capability for performance electric motorcycle and off-road projects. With the approved BMS, controller, cable and thermal design, it can support 10kW, 12kW, 15kW and higher vehicle programs. Final dimensions are customized to the bike.
customers VALUE
● More capacity for longer riding and repeated acceleration
● High-discharge platform for performance motorcycle projects
● Custom dimensions, connector, label and BMS review
This product is designed as a project-based battery module for motorcycle brands, importers, distributors, assemblers and performance builders. The 72V 40Ah Electric Motorcycle Lithium Battery combines a removable steel case, LCD power display, top handle and project-defined interface with a 20S8P 21700 cell structure. The supplied sheet lists 39.2Ah minimum capacity, up to 40A maximum charging current, and a 340A / 400A continuous-discharge platform depending on the approved BMS and pack configuration. Instead of publishing one fixed enclosure size, HSS Energy confirms dimensions against the actual battery bay before sample approval.

Core Sales Angles
1. High-Discharge Performance
For a high power electric motorcycle battery, output capability is the first filter. The 340A / 400A BMS-dependent discharge platform gives this battery a clear role in 10kW, 12kW, 15kW and potentially higher motorcycle programs, subject to full system approval.
2. 40Ah Gives the Offer More Range Value
For a 72V 40Ah lithium battery, the 40Ah platform creates a stronger range-and-performance story than lower-capacity alternatives, helping trade customers offer something beyond a basic city-commuter battery.
3. Better Match for Off-Road Enthusiast Builds
For a 72V off-road motorcycle battery, off-road and enthusiast users care about acceleration, climbing load and repeatable power delivery. This platform is positioned for that higher-demand customers segment while remaining removable.
4. Finished Design Improves User Experience
For a 72V 40Ah motorcycle battery, the steel enclosure, carry handle, LCD display and accessible front interface make the pack easier to remove, understand and service than a bare internal battery assembly.
5. Custom Dimensions Make the Quote More Practical
For a 72V 40ah lithium battery pack, the electrical platform is defined, but the enclosure and interface stay project-specific. That helps the battery fit the motorcycle instead of forcing the motorcycle to fit a stock battery box.
6. OEM / ODM Support for Real Trade Projects
Cell model, BMS configuration, connector, label, display requirement, interface position and final dimensions can be frozen in the approved drawing before sample and bulk production. This is useful for vehicle brands, importers, distributors and performance shops that need their own sellable configuration rather than a generic catalog pack.
Who This Battery Is For
· Electric motorcycle brands developing or upgrading 72V performance models
· Off-road motorcycle projects with higher discharge demand
· Importers and distributors looking for a stronger-value product line
· Performance shops and custom builders serving enthusiast riders
These current figures are simple nominal-voltage screening references, not guaranteed battery current requirements. Actual current depends on operating voltage, controller behavior, drivetrain efficiency, load and duty cycle.
Good Fit / Review Another Configuration
Good Fit When
Review Another Configuration When
72V architecture + 40Ah capacity fit the vehicle target.
A different voltage or capacity class is required.
10-15kW+ target can be matched with an approved full system.
Current / thermal demand exceeds the approved design.
Removable steel-case format adds service value.
The bike needs a sealed integrated pack.
Custom dimensions can be approved from the bike drawing.
The fixed battery bay is incompatible with this format.
Quality, Packaging and Delivery
Foreign trade customers evaluate more than specifications. Incoming inspection, controlled assembly, final testing and export packaging all affect whether the order can be repeated reliably. The supplied process visual is used here as a trust section rather than as proof of an unverified certification or test standard.

Send Requirement
Bike data, controller, charger, power target, quantity
Can this battery support 10kW, 12kW or 15kW motorcycles?
It is positioned for these power classes and potentially higher, but the final approved capability depends on the BMS, controller current, motor load, cable, connector and thermal design.
Can I use my own brand?
Yes. OEM / ODM label, connector and project-based configuration can be reviewed.
Are the dimensions fixed?
No. Final dimensions follow the approved battery-bay and project drawing.
Does 340A / 400A apply to every order?
No. It is tied to the approved BMS and finished pack configuration.
Can it fit every 72V motorcycle?
No. Voltage alone does not determine fit. Current demand, charger logic, dimensions and interface layout all require review.
What is the fastest way to get a quotation?
Send the battery-bay dimensions, controller current, charger information, target power level and quantity.
