12v lithium battery
What is a 12V Lithium Battery?
A 12V lithium battery is a rechargeable battery pack typically made by connecting four 3.2V LiFePO4 cells or three 3.7V Li-ion cells in series, providing a nominal voltage of around 12.0V or 11.1V depending on the chemistry. It serves as a modern, high-performance alternative to traditional 12V lead-acid batteries. With advantages such as longer cycle life, lightweight structure, high energy efficiency, and built-in protection features, 12V lithium batteries are widely used in solar energy storage, RV and marine systems, medical devices, security equipment, and portable power supplies.
A Smarter, Lighter Alternative to Lead-acid
Compared to 12V sealed lead-acid (SLA) batteries, 12V lithium batteries are up to 70% lighter, charge up to 5 times faster, and last 3 to 5 times longer in terms of cycle life. They offer stable voltage output, low internal resistance, and minimal self-discharge, ensuring reliable power delivery and reduced maintenance. With support for series or parallel expansion, 12V lithium packs can also be scaled into 24V, 36V, or 48V systems, making them highly versatile for both fixed and mobile applications.

Why Choose 12V Lithium Batteries for Your Business?
Smart Replacement for Lead-Acid Systems with Superior Efficiency and Lifecycle Value
12V lithium batteries—typically composed of 4 cells in series (4S configuration)—have become the industry-standard solution for replacing traditional 12V lead-acid batteries. With higher energy efficiency, lighter weight, longer lifespan, and intelligent BMS integration, 12V lithium batteries are widely adopted in commercial and industrial applications such as solar energy storage, UPS, RVs, marine systems, security setups, and mobile power solutions. Here’s why enterprise clients rely on them:
Drop-in Replacement for 12V Lead-Acid Systems
12V lithium batteries are designed with the same voltage profile as legacy lead-acid units, making them fully compatible with existing 12V systems. Whether used in telecom backup, vehicle starters, or solar storage, businesses can upgrade to lithium without redesigning their systems.
Long Cycle Life and Low Total Cost of Ownership
With a typical cycle life of 2000–5000 cycles (compared to 300–500 for lead-acid), 12V lithium batteries significantly reduce maintenance and replacement costs. Over time, this provides better ROI for clients managing fleets, off-grid systems, or industrial backup power networks.
Integrated BMS for Smart Protection and Monitoring
All our 12V lithium batteries come with built-in Battery Management Systems (BMS) to protect against overcharge, over-discharge, short circuit, and thermal risks. The smart BMS ensures real-time monitoring, safety, and performance consistency in critical use cases.
Modular and Customizable for Scalable Solutions
12V battery packs can be configured in series or parallel to form 24V, 48V, or higher-voltage systems. Our factory offers full OEM/ODM customization—including casing, capacity, terminals, communication protocol (CAN/RS485), and branding—tailored to your technical and commercial requirements.
