Product Description
Ten parallel 21700 cells per series group give the 72V 50Ah Electric Motorcycle Lithium Battery its 50Ah capacity. The steel enclosure and approximately 18kg reference mass need to be included in mounting and handling decisions. The recommended charging voltage is 84V. High-current options remain dependent on the selected cells, BMS, wiring and cooling within the finished motorcycle installation.
The Complete Current Path
A high discharge electric motorcycle battery needs a complete current path suitable for the controller demand. The source lists 340A or 400A configuration references, subject to the selected cells, BMS and finished design. These figures do not establish a universal vehicle rating. Thermal performance, cables, busbars and the mating connector are assessed together.

Product Details
The 50Ah Capacity Option
The 72V 50Ah lithium battery offers more nominal capacity than the 30Ah and 40Ah versions in this series. That reserve can be useful for longer operating periods, but the approximately 18kg mass also affects vehicle balance. Average load, gradients and charging frequency provide a better range estimate than capacity alone.
NCM Cell Platform
This 72V NCM electric motorcycle battery uses 21700 cells in a 20S10P layout. Ten cells in each parallel group provide the 50Ah capacity. The chosen cell model must remain part of the order specification because current capability and thermal performance depend on more than the cell format or chemistry name.
Battery Compartment
An electric motorcycle battery pack needs a clear installation and removal path. For this approximately 18kg reference, the vehicle drawing should show the support surface, retention points, cable route and access to the connector. Enclosure dimensions are project-specific and are released with that drawing.
Metal Case and Service Access
The 72V 50Ah motorcycle battery is presented in a metal enclosure with a power display. The service arrangement defines how the pack is restrained, disconnected and removed. Any handle, front connection or display location should match the final enclosure drawing, rather than be selected only for appearance.
Check the complete high-current path
The cell arrangement does not determine the connector rating. Confirm BMS limits, conductor size, fuse strategy and terminal temperature at the intended load. Include the retention method for the approximately 18kg pack in the sample acceptance.

FAQ
What should I compare before selecting 72V 50Ah Electric Motorcycle Lithium Battery?
maximum continuous discharge: 340A / 400A or customer-designated configuration, subject to approved BMS and finished pack design for this model, compared with 340A / 400A depending on approved BMS configuration for 72V 30Ah Electric Motorcycle Lithium Battery; approx. weight: Approx. 18kg for this model, compared with Approx. 12kg for 72V 30Ah Electric Motorcycle Lithium Battery.
Can I reuse a charger with this battery?
Recommended Charge Voltage: 84V; Maximum Charge Current: 50A; supplied sheet recommends 0.5C charging. Match the charger profile, polarity and connection to the ordered assembly. A voltage-class label alone does not establish compatibility with an existing charger.
How much installation space should I allow for this battery?
Dimensions: According to custom requirements / approved project drawing; Approx. Weight: Approx. 18kg. Allow access to the terminals or connector and room for the cable bend and retention hardware. Compare the finished assembly drawing with the actual equipment space before fixing the mounting points.
What discharge limit should the equipment designer use?
Maximum Continuous Discharge: 340A / 400A or customer-designated configuration, subject to approved BMS and finished pack design. Retain the stated conditions when checking the operating load, connector and wiring.
