Great Power A-Grade 100Ah LiFePO4 Cell

The Great Power GSP50160119F is specified as an A-Grade LiFePO4 cell, making it suitable for professional battery-pack construction.

A-Grade cells are preferred for applications where consistent cell quality and electrical characteristics are important.

For multi-cell battery assembly, cells should preferably be matched according to:

Voltage

Capacity

Internal resistance

State of charge

Overall cell condition

Proper cell matching can help improve the consistency and performance of the completed battery pack.

0.28mΩ Internal Resistance

This Great Power cell has a specified internal resistance of:

0.28mΩ

Low internal resistance can help minimize voltage drop and reduce internal heat generation when current passes through the cell.

Actual measured resistance may vary depending on:

Cell temperature

State of charge

Measurement equipment

Testing method

Cell condition

For professional battery assembly, using cells with closely matched resistance is recommended.

5000 Cycle Life

The cell is specified with a:

5000 Cycle Life

This makes the cell suitable for applications requiring regular charging and discharging, including:

Solar energy storage

Home backup

Inverter systems

UPS systems

Commercial energy storage

Portable power stations

EV applications

Off-grid systems

Actual cycle life can vary depending on:

Depth of discharge

Charging voltage

Charging current

Discharge current

Operating temperature

BMS settings

Cell balancing

Storage conditions

1C Continuous Discharge

The product specification indicates support for:

1C Continuous Discharge

For a 100Ah cell:

1C = approximately 100A

This means the cell is specified to support approximately 100A continuous discharge under the applicable conditions.

The actual usable current of a complete battery pack will also depend on the BMS, busbars, cables, terminals, fuse, temperature and other system components.

100Ah Capacity & Nominal Energy

Each cell provides:

3.2V × 100Ah = 320Wh

Therefore, one Great Power 100Ah cell stores approximately:

320Wh / 0.32kWh Nominal Energy

The total energy of a battery pack depends on the series and parallel configuration.

Battery Configuration Examples

4S 100Ah – 12.8V 100Ah

Using 4 cells in series:

4 × 3.2V = 12.8V

Nominal energy:

12.8V × 100Ah = 1.28kWh

Suitable for a 12V-class LiFePO4 battery.

8S 100Ah – 25.6V 100Ah

Using 8 cells in series:

8 × 3.2V = 25.6V

Nominal energy:

25.6V × 100Ah = 2.56kWh

Suitable for a 24V-class LiFePO4 battery.

16S 100Ah – 51.2V 100Ah

Using 16 cells in series:

16 × 3.2V = 51.2V

Nominal energy:

51.2V × 100Ah = 5.12kWh

Suitable for 48V/51.2V-class LiFePO4 battery systems.

Parallel Configuration

Parallel connections increase total capacity while maintaining the same nominal voltage.

Configuration Approx. Capacity

1P 100Ah

2P 200Ah

3P 300Ah

4P 400Ah

For example:

16S2P = 51.2V 200Ah

Nominal energy:

51.2V × 200Ah = 10.24kWh

The final configuration should be selected according to the required voltage, capacity, BMS rating, inverter and application.

Cell Dimensions

The product image specifies:

50 × 160 × 119mm

Approximate dimensions:

Width: 50mm

Length: 160mm

Height: 119mm

These dimensions should be considered when designing a battery enclosure.

Adequate clearance should be provided for:

Cell terminals

Busbars

Insulation

BMS wiring

Cell supports

Battery cables

Actual physical dimensions should be verified before manufacturing a custom battery box.

Cell Weight

The specified cell weight is:

1.92 ± 0.05kg

Approximate weight range:

1.87–1.97kg

The final battery weight will depend on the number of cells and additional components such as the BMS, busbars, cables, enclosure, terminals and protection equipment.
