CFE-1280 SE High-Performance Lithium Battery Replacement Module

12.8V 100Ah LiFePO4 | Intelligent BMS Protection | Lightweight, Maintenance-Free, and Reliable Backup Power for Critical Applications

The CFE-1280 SE is a high-performance 12V 100Ah lithium battery built with advanced Lithium Iron Phosphate (LiFePO4) chemistry and engineered for backup power applications that demand high reliability, reduced weight, and long service life. Designed as a direct upgrade for traditional lead-acid batteries, it delivers the familiar 12.8V 100Ah platform while offering significant advantages in cycle life, efficiency, safety, and maintenance.

With an integrated intelligent hardware BMS, independent charge and discharge management, and a rugged IP65-rated enclosure, the CFE-1280 SE is ideal for data centers, industrial control systems, renewable energy storage, and other mission-critical environments. For customers looking for a dependable power supply battery that can replace aging lead-acid units without adding maintenance complexity, this module provides a practical and efficient solution.

Its flexible design also supports both series and parallel expansion, allowing users to scale from a single 12V 100Ah lithium battery module to larger systems, including configurations similar to a 12V 200Ah lithium battery or a 24V LiFePO4 battery, depending on project requirements.

Product Features & Advantages

High-Performance LiFePO4 Core

The CFE-1280 SE uses stable and safe LiFePO4 cells with high energy efficiency, low self-discharge, and no memory effect. Compared with lead-acid batteries of the same nominal capacity, it offers a more stable discharge voltage plateau and more consistent power delivery, making it a stronger choice for demanding backup power scenarios.

Integrated Intelligent Protection System

The built-in hardware BMS provides real-time monitoring and comprehensive protection for voltage, current, and temperature. It also includes independent control of charge and discharge circuits, helping prevent improper operation and improving overall system safety. This industrial-grade protection design ensures stable performance in critical environments.

Excellent Cycle Life and Lower Lifetime Cost

Engineered for up to 3,000 cycles at 80% depth of discharge, the CFE-1280 SE can last 3 to 6 times longer than conventional lead-acid batteries. Its extended lifespan helps reduce replacement frequency, minimize downtime, and lower disposal and maintenance costs over the full lifecycle.

Strong Environmental Adaptability

With a wide operating temperature range from -20°C to 70°C during discharge and an IP65 dust- and water-resistant enclosure, this battery is built to perform reliably in harsh environments. Whether installed in hot, humid, cold, or dusty conditions, it delivers stable and consistent operation.

Flexible System Scalability

The CFE-1280 SE supports both series connection up to 51.2V system voltage and parallel expansion, making it suitable for a wide range of applications. Users can start with a single module and expand into a 24V 100Ah lithium battery system, a 24V LiFePO4 battery bank, or a larger-capacity backup solution based on actual energy demand.

Install-and-Forget, Maintenance-Free Design

The module is fully compatible with standard lead-acid battery installation dimensions and terminal connection logic, allowing for easier replacement in existing systems. Once installed, it requires no equalization charging, no electrolyte checks, and no routine watering or maintenance, making it a true fit-and-forget energy solution.

Application Scenarios

Off-Grid and Hybrid Renewable Energy Systems

As a scalable power supply battery, the CFE-1280 SE works well in off-grid and hybrid solar or wind systems, improving renewable energy utilization and overall supply reliability. It can also be configured into larger banks for projects requiring a 24V LiFePO4 battery or 24V 100Ah lithium battery architecture.

Security and Emergency Lighting Systems

The battery ensures uninterrupted power for surveillance systems, access control, emergency lighting, and other essential safety equipment during power outages, helping maintain system continuity when it matters most.
