Why Choose a Low-Voltage LiFePO4 Battery System?
Low-voltage battery systems are widely used because they are flexible, easy to install and suitable for many residential and small-scale energy storage applications.
Compared with traditional lead-acid batteries, LiFePO4 batteries can provide longer service life, higher usable energy and more stable performance when properly configured and operated.
A low-voltage system also makes it easier for installers and distributors to select a suitable battery according to the required voltage, capacity, installation method and inverter system.
Available Voltage and Capacity Options
We provide low-voltage battery solutions for different project requirements.

12V batteries are suitable for small backup systems, mobile power applications, communication equipment, small off-grid systems and replacement of traditional lead-acid batteries.
Common applications include:
- Small solar systems
- RV and marine power
- Backup lighting
- Telecom and monitoring equipment
- Small DC power systems
24V LiFePO4 Batteries
24V battery systems provide a higher voltage option for medium-sized backup and off-grid applications.
They are suitable for:
- Small residential solar systems
- Off-grid cabins and homes
- Backup power equipment
- Small pumps and electrical loads
- 24V inverter systems
48V/51.2V LiFePO4 Batteries
48V/51.2V systems are commonly used for residential energy storage and small commercial applications. They can provide higher system efficiency and are compatible with many hybrid and off-grid inverters.
Typical applications include:
- Home energy storage
- Solar backup power
- Off-grid residential systems
- Small commercial buildings
- Communication and data equipment
- Energy storage systems requiring modular expansion
Battery capacity can be customized according to the project. Options may include 100Ah, 200Ah, 300Ah and other capacities, subject to the final design and product configuration.
Battery Designs for Different Installation Requirements
We offer several battery form factors to match different installation environments.
Wall-Mounted LiFePO4 Batteries
Wall-mounted batteries are suitable for homes and small offices where floor space is limited. Their compact design allows convenient installation in utility rooms, garages, storage rooms and other indoor locations.
Rack-Mounted LiFePO4 Batteries
Rack-mounted batteries are suitable for solar installers, telecom projects, equipment rooms and modular energy storage systems. Multiple battery modules can be installed in a standard cabinet or rack for easier expansion and maintenance.
Floor-Standing and Integrated Batteries
Floor-standing batteries are suitable for applications requiring larger capacity or a more integrated design. Some configurations can combine the battery pack, BMS, display and protective components in one enclosure.
The final battery design depends on the required capacity, installation method, working environment and inverter system.
Battery Management and Communication
A reliable battery management system is important for the safe operation of a LiFePO4 battery.
Depending on the selected model, the battery system may include protection and monitoring functions such as:
- Overcharge protection
- Over-discharge protection
- Over-current protection
- Short-circuit protection
- Temperature monitoring
- Cell balancing
- State-of-charge monitoring
- Fault alarm and protection
CAN, RS485 and other communication options may be available for compatible inverter and energy storage systems. Before production, we recommend confirming the inverter brand, communication protocol and connection requirements.
Applications of Low-Voltage LiFePO4 Batteries
Our low-voltage lithium battery solutions can be used in a variety of applications.
Residential Backup Power
Store energy from solar panels or the grid and use it during power outages or peak-demand periods.
Off-Grid Solar Systems

Frequently Asked Questions
What is a low-voltage LiFePO4 battery?
A low-voltage LiFePO4 battery is a lithium iron phosphate battery system designed for applications such as residential backup, off-grid power and small commercial energy storage. Common system voltages include 12V, 24V and 48V/51.2V.
Is a 48V battery the same as a 51.2V battery?
Many lithium battery systems are marketed as 48V systems, while the nominal voltage of a 16-cell LiFePO4 battery pack is commonly 51.2V. Compatibility should always be confirmed with the inverter and system design.
Can low-voltage batteries be connected in parallel?
Many models support parallel connection for capacity expansion, but the exact number of parallel units and connection method depend on the battery model and BMS design.
Can the battery communicate with my inverter?
CAN or RS485 communication may be available for compatible models. Please provide the inverter brand and model before ordering so the communication requirements can be checked.
Do you support OEM battery branding?
Yes. We support OEM branding and customized battery solutions for wholesale customers and project-based orders. The MOQ and customization details depend on the product configuration.
How do I choose the correct battery capacity?
Battery capacity depends on your load power, daily energy consumption, backup duration, inverter specifications and installation conditions. Please contact us with your project details for a recommendation.
