What Is a 24V LiFePO4 Battery?
A 24V LiFePO4 battery is normally built from eight 3.2V LiFePO4 cells connected in series (8S). This gives the battery pack a nominal voltage of 25.6V, which is commonly referred to as a deep cycle 24V battery system.
When fully charged, an 8S LiFePO4 battery reaches about 29.2V. The exact discharge cut-off voltage depends on the cell specification, BMS settings and application requirements.
Compared with lead-acid batteries, LiFePO4 batteries provide higher usable capacity, longer cycle life and more stable voltage under load. They are commonly used in solar systems, RVs, marine equipment, robotics, backup power and industrial applications.

Custom 24V LiFePO4 Battery Manufacturer in China
Did you find that a standard 24V battery matches your system voltage but still falls short on current, runtime, size, or communication requirements? That is a common problem in industrial battery projects. A 24V-class LiFePO4 battery must match more than nominal voltage. Capacity, continuous current, peak current, BMS limits, charger voltage, operating temperature and available installation space all affect real system performance.
VTCBATT develops custom 24V / 25.6V LiFePO4 battery packs around the actual load and mechanical requirements of the application. Battery capacity, charge and discharge current, enclosure size, connector, wire harness, BMS functions and communication interfaces can all be customized where required.
Each battery pack uses LiFePO4 cells with an integrated BMS for functions such as cell balancing, over-voltage protection, under-voltage protection, over-current protection, short-circuit protection and temperature monitoring. LiFePO4 chemistry also offers high thermal stability, making it suitable for applications that require long cycle life and reliable operation.
Custom 24V LiFePO4 batteries are commonly used in solar and energy storage systems, RV and marine equipment, AGVs and robotics, telecom backup, industrial equipment and other 24V power systems. The correct battery should be selected from the system’s actual runtime, continuous load, peak load, charger, temperature range and mechanical space, rather than voltage and capacity alone.

Final pack design should be based on the actual load, charger, operating temperature, available space and mechanical interface.
How to Choose a 24V LiFePO4 Battery?
Choosing a 24V LiFePO4 battery requires more than matching voltage and capacity. The battery must also support the system's runtime, continuous current, peak load, charger, temperature range and available installation space.
Battery capacity determines runtime. A 25.6V 100Ah LiFePO4 battery stores about 2.56kWh of nominal energy, while a 50Ah battery stores about 1.28kWh.
Check: Load power · Runtime · Usable DoD · Efficiency
The battery and BMS must support both the normal continuous load and short peak currents. Motors, pumps, inverters and AGVs can require much higher current during startup than during normal operation.
A standard 8S LiFePO4 battery reaches about 29.2V at full charge. The charger must use a voltage and charging profile compatible with the battery and BMS. A 24V lead-acid charger should not be assumed to be compatible with a LiFePO4 battery.
LiFePO4 batteries can discharge at lower temperatures than they can normally be charged. For cold environments, the pack may need low-temperature charge protection or a self-heating system.
The BMS should match the required voltage, current and protection functions. Industrial systems may also need CAN, RS485, UART, Bluetooth or other communication interfaces.
A battery can meet the electrical requirements but still fail the project if it does not fit the available space. Enclosure size, mounting direction, connector position, cable length and environmental protection should be confirmed before final design.

24V LiFePO4 batteries are suitable for telecom equipment, security systems and UPS backup where stable standby power is required.
Key requirements: long standby life, low maintenance, BMS monitoring and reliable recharge performance.
24V battery packs can be customized for industrial machines, instruments, mobile equipment and control systems.
Key requirements: load current, enclosure size, connector, temperature range, mounting method and CAN/RS485 communication.
A 24V LiFePO4 battery can provide a long cycle life, but there is no single number that applies to every pack.
Service life depends on cell quality, depth of discharge, charge rate, temperature and the actual duty cycle. Frequent deep discharge, high current and high temperature can shorten life.
For engineering projects, cycle life should be checked under the test conditions listed for the specific cell or battery pack.
Use a charger designed for an 8S LiFePO4 battery.
A typical 24V-class LiFePO4 pack is 25.6V nominal and reaches about 29.2V at full charge. The charger voltage and charge current must stay within the limits of the cells and BMS.
Do not assume that an existing 24V lead-acid charger is suitable without checking its charging profile.
In many systems, yes.
But voltage alone is not enough to confirm a safe replacement. Check the charger, inverter or controller cut-off settings, continuous current, startup current, temperature range, dimensions and terminal layout.
A successful replacement depends on complete system compatibility, not only the 24V rating.
Choose the BMS from the actual load current.
The BMS continuous-current rating should be higher than the normal operating current. It must also support short peak loads from equipment such as motors, pumps or inverters.
Battery capacity affects runtime. BMS current depends on the actual load.
Yes, but it depends on the BMS design. Some 24V LiFePO4 batteries are designed for series or parallel connection, while others are not.
For parallel use, the batteries should be closely matched in voltage, capacity and state of charge. For series use, the BMS must be designed to handle series operation and the higher total system voltage.
Check the battery manufacturer’s series and parallel limits before connecting multiple packs.
Generally, standard 24V LiFePO4 batteries should not be charged below 0°C. Low-temperature charging can damage the cells or reduce their service life.
For cold environments, special low-temperature LiFePO4 batteries can be designed with low-temperature cells, self-heating, or controlled preheating to support charging below 0°C.
Always confirm the minimum charging temperature for the specific cell and battery pack before use.
Yes. 24V LiFePO4 batteries can support CAN, RS485 or Bluetooth when the BMS is designed with the required communication interface.
CAN and RS485 are commonly used for communication with inverters, chargers, AGVs and industrial equipment. Bluetooth is mainly used for local battery monitoring and diagnostics.
For custom battery packs, the communication protocol, data format and connector should be confirmed during the design stage.
Please provide the voltage, required capacity or runtime, continuous current, peak current, charger specification, operating temperature and available battery size.
Also include any requirements for connector, cable, CAN/RS485/Bluetooth communication, enclosure and IP rating.
For motors, inverters or other high-current loads, a real current waveform or startup-current data is especially helpful.
The required documents depend on the battery design, application and destination market.
Common documents may include UN38.3, MSDS, CE and RoHS, with additional certifications available for specific cells or battery packs where applicable.
Certification scope should be confirmed for the exact battery configuration. A certificate for one cell or pack should not be assumed to cover every custom design.
Check both continuous power and startup power.
Convert the equipment load into battery current, then compare it with the continuous and peak-current limits of the cells and BMS. Peak duration also matters.
A battery may have enough Ah for the required runtime but still be unable to supply a large startup current. Capacity and power capability are separate design requirements.
