24V, 36V, 48V, 52V, 60V and 72V 40Ah 50Ah LiFePO4 Battery Pack for AGV, Golf Cart and Energy Storage

Choosing a suitable lithium battery pack requires more than comparing voltage and capacity. AGVs, golf carts and energy storage systems have different operating conditions, discharge requirements, installation spaces and charging methods. A battery pack designed for one application may not be suitable for another, even when the nominal voltage and capacity are the same.

A 24V 40Ah LiFePO4 battery pack, for example, may be used in an automated guided vehicle, while a 48V 50Ah battery pack may be designed for a golf cart. A 72V 50Ah battery pack may serve a mobile energy storage system or industrial equipment. Each application requires a battery configuration that matches its electrical system, mechanical structure and operating environment.

This guide explains the specifications, battery chemistry, application requirements and customization process for 24V, 36V, 48V, 52V, 60V and 72V 40Ah and 50Ah LiFePO4 battery packs.

1. What Is a LiFePO4 Battery Pack?

A LiFePO4 battery pack uses lithium iron phosphate as the positive electrode material. LiFePO4 is a lithium-ion battery chemistry used in applications that require rechargeable energy storage, stable operating characteristics and a long service life.

Compared with lead-acid batteries, LiFePO4 battery packs offer several design advantages:

• Lower weight for equivalent energy capacity in many applications.
• A flatter discharge voltage profile.
• Rechargeable operation with a suitable battery management system.
• Low self-discharge during storage.
• A chemistry that does not contain cobalt or nickel in the cathode material.
• Flexible pack configurations for industrial equipment and energy storage.

LiFePO4 is not automatically suitable for every application. The battery must be designed around the equipment’s current requirements, charging voltage, operating temperature and available installation space.

For AGVs, golf carts and energy storage systems, the battery pack design should also consider communication, protection, thermal management and maintenance requirements.

2. LiFePO4 Battery Pack Voltage and Capacity

Battery voltage and capacity are two of the most important specifications.

Voltage indicates the electrical potential of the battery pack. Capacity, measured in ampere-hours (Ah), indicates how much electrical charge the battery can store under specified test conditions.

The approximate nominal energy of a battery pack can be calculated as:

Nominal Energy (Wh) = Nominal Voltage (V) × Rated Capacity (Ah)

예를 들어

• 24V × 40Ah = 960Wh
• 24V × 50Ah = 1,200Wh
• 48V × 40Ah = 1,920Wh
• 48V × 50Ah = 2,400Wh
• 72V × 40Ah = 2,880Wh
• 72V × 50Ah = 3,600Wh

These figures are nominal energy values rather than guaranteed usable energy. Actual available energy depends on the battery management system, discharge current, temperature, cutoff voltage, cell characteristics and operating conditions.

Buyer-Focused Battery Specification Table

These voltage levels may be selected for custom equipment where the motor controller, inverter or power system requires a specific nominal voltage.

A 52V LiFePO4 battery pack is not interchangeable with a 48V battery pack simply because the voltage difference is small. The charging system and operating voltage range must be compatible with the selected battery.

52V LiFePO4 Battery Pack

A 52V 40Ah battery pack provides approximately 2,080Wh of nominal energy.

A 52V 50Ah battery pack provides approximately 2,600Wh.

A 72V 40Ah battery pack provides approximately 2,880Wh of nominal energy.

A 72V 50Ah battery pack provides approximately 3,600Wh.

72V systems require attention to insulation, wiring, connector selection, BMS voltage rating and charger compatibility.

The battery pack should be designed according to the equipment’s maximum operating voltage, charging requirements and applicable safety standards.

6. LiFePO4 Battery Pack for Energy Storage Systems

LiFePO4 battery packs are used in energy storage systems for backup power, mobile equipment and other applications.

A 24V, 36V, 48V, 52V, 60V or 72V battery pack may be considered depending on the inverter or power system requirements.

For example, a 48V 50Ah battery pack provides approximately 2.4kWh of nominal energy. The usable energy depends on the permitted depth of discharge, operating temperature and BMS settings.

Energy Storage Battery Design

Energy storage applications may require:

• Stable voltage output.
• Suitable continuous discharge current.
• BMS communication.
• Temperature monitoring.
• Battery state-of-charge estimation.
• 과충전 및 과방전 방지.
• Short-circuit protection.
• A suitable enclosure.
• Parallel connection capability, if supported by the design.

Energy storage systems may have different requirements from AGVs or golf carts. The battery design should be matched to the inverter, charging source and load profile.

Battery Capacity and Runtime

A simplified runtime calculation is:

Runtime (hours) = Usable Energy (Wh) ÷ Load Power (W)

For example, a 48V 50Ah battery pack has approximately 2,400Wh of nominal energy.

If the load is 400W, the theoretical runtime is:

2,400Wh ÷ 400W = 6 hours

Actual runtime will be lower or different depending on battery efficiency, load variation, cutoff voltage and operating temperature.

7. LiFePO4 Battery Pack Configuration

A LiFePO4 battery pack consists of cells connected in series and parallel.

Series connections increase voltage. Parallel connections increase capacity.

A simplified example:

• 8S configuration: approximately 25.6V nominal.
• 12S configuration: approximately 38.4V nominal.
• 16S configuration: approximately 51.2V nominal.
• 20S configuration: approximately 64V nominal.
• 24S configuration: approximately 76.8V nominal.

These are common LiFePO4 nominal voltage configurations, not exact matches for every product name. The final battery configuration must be selected according to the required voltage range and application.

For example, a 48V LiFePO4 battery pack often uses a 16S configuration with a nominal voltage of 51.2V. A 72V LiFePO4 battery pack may use a 24S configuration with a nominal voltage of 76.8V.

This is why product naming, nominal voltage and actual cell configuration should be clearly specified on the technical datasheet.
