The cell features a cylindrical Ø33 mm × H140 mm form factor and supports continuous discharge up to 2C, with a maximum pulse discharge rate of 3C for 10 seconds under the specified test conditions.
Its compact cylindrical design makes it suitable for battery pack configurations where space utilization, modularity, and consistent electrical performance are important.
The cell provides a nominal capacity of 15Ah, offering a flexible building block for customized lithium battery packs.
Multiple cells can be configured in series and parallel according to the required voltage and capacity of the application.
With a nominal voltage of 3.2V, the cell can be integrated into customized lithium battery systems according to the customer's required voltage platform.
The cell dimensions are:
Ø33 mm × H140 mm
The cylindrical form factor provides a compact and modular solution for battery pack design.
According to the supplied technical specification, the maximum continuous discharge current is 2C at 25±2°C.
For a 15Ah cell, this corresponds to a maximum continuous discharge current of approximately 30A, subject to the specified test conditions and actual battery-pack design.
The specified maximum pulse discharge rate is 3C at 25±2°C, 100% SOC, for 10 seconds.
This makes the cell suitable for applications requiring short-duration higher-power output.

The 15Ah cell supports a standard discharge rate of 0.5C at 25±2°C.
For applications requiring higher power output, the technical specification allows:
Maximum continuous discharge: 2C
and:
Maximum pulse discharge: 3C for 10 seconds at 25±2°C and 100% SOC.
This discharge capability makes the cell suitable for battery systems that experience short periods of increased power demand, such as acceleration, starting, climbing, or other dynamic operating conditions.
For a 15Ah cell:
0.5C = 7.5A
2C = 30A
3C = 45A pulse
Actual pack-level output depends on the number of cells connected in parallel, BMS settings, thermal conditions, connectors, busbars, and the overall battery design.
According to the supplied technical specification, the cell has a stated cycle life of:
The cycle-life specification is based on a 0.5C charge/discharge cycle test at 25±2°C, with the manufacturer's specified testing method.
Actual service life in a finished battery pack will depend on factors including:
Charge and discharge rate
Depth of discharge
Operating temperature
BMS settings
Charging strategy
Cell consistency
Mechanical and thermal design
Therefore, battery manufacturers should evaluate cycle life according to the actual application conditions.
Temperature is an important factor in lithium battery performance.
The supplied specification identifies the following optimal operating ranges:
Charging: 15–35°C
Discharging: 10–35°C
The technical documentation also specifies different discharge cut-off voltage requirements depending on cell temperature:
Cell temperature >0°C: 2.5V
Cell temperature <0°C: 2.0V
For battery-pack applications operating in particularly hot or cold environments, GBE Battery recommends designing the complete battery system according to the actual operating conditions, including BMS protection, thermal management, charging strategy, and enclosure design.
The 15Ah cylindrical lithium battery cell can be considered for a variety of customized battery-pack applications.
The cell can be used as a building block for customized electric scooter and electric motorcycle battery packs.
Depending on the required voltage and capacity, cells can be configured into different series-parallel combinations.
For electric three-wheelers requiring a compact and modular power system, cylindrical cells provide flexibility for battery-pack design.
Multiple 15Ah cells can be assembled into customized battery systems for golf carts and other light electric vehicles.
The cell can also be evaluated for:
Electric mobility vehicles
Small utility vehicles
Personal transportation equipment
Light-duty electric vehicles
The cell may also be considered for customized industrial battery systems where stable power output and modular battery construction are required.
GBE Battery does not only supply individual lithium battery cells.
We also support customers in developing customized lithium battery packs according to their application requirements.
Our engineering team can work with customers on:
Voltage configuration
Capacity configuration
Series and parallel configuration
Battery dimensions
BMS selection
Discharge current
Charging requirements
Connector selection
Communication functions
Battery enclosure
Thermal management
This allows the 15Ah cell to be integrated into different battery platforms according to the customer's vehicle or equipment requirements.
One of the advantages of cylindrical lithium battery cells is their flexibility in battery-pack configuration.
For example, a battery manufacturer can combine cells in series to increase voltage and in parallel to increase capacity.
The basic relationship is:
Pack Voltage = Cell Voltage × Number of Cells in Series
Pack Capacity = Cell Capacity × Number of Cells in Parallel
For example, a 16S configuration using 3.2V cells has a nominal system voltage of approximately:
16 × 3.2V = 51.2V
A 2P configuration using 15Ah cells provides:
15Ah × 2 = 30Ah
Therefore, a 16S2P configuration would theoretically provide approximately:
This type of configuration can be considered for electric two-wheeler and other light electric mobility applications, subject to the actual vehicle requirements.
This 15Ah lithium battery cell is particularly suitable for customers who manufacture their own battery packs.
GBE Battery can support customers with:
Cell Supply → Pack Design → BMS Matching → Battery Assembly → Testing → Export
