CFE-1280S Pro

The CFE-1280S Pro is a 12.8V 100Ah LiFePO4 battery designed to replace traditional lead-acid batteries in standard 12V systems. It offers a simple upgrade path for users who want better safety, longer service life, and more stable performance without changing their existing voltage architecture or installation habits. As a reliable China lead acid battery replacement, it is suitable for RVs, backup power, telecom systems, marine applications, and off-grid energy storage.

Product Overview

The CFE-1280S Pro is built for customers seeking a dependable 12V 100Ah lithium battery for everyday energy storage and backup applications. With a nominal voltage of 12.8V and rated capacity of 100Ah (@1C), this battery delivers stable output and practical system compatibility for common 12V platforms.

The recommended charging voltage is 14.2V. It supports 50A standard continuous charge and 100A standard continuous discharge, with up to 60A maximum continuous charge and 120A maximum continuous discharge. It also supports 125A pulse discharge for 5 seconds, helping cover short inrush currents or temporary peak load demands.

For users looking for a compact power supply battery with easier maintenance and better lifecycle value than lead-acid products, the CFE-1280S Pro offers a well-balanced solution. It can also be integrated into scalable systems for customers evaluating a 24V LiFePO4 battery or 24V 100Ah lithium battery platform through series expansion.

Key Features & Benefits

1. Drop-in Replacement for 12V Lead-Acid Systems

The CFE-1280S Pro is designed as a direct replacement for traditional lead-acid batteries in 12V systems. Users can upgrade to lithium technology without changing the original system voltage or installation method.

2. Stable Output for Daily Use

With 12.8V nominal voltage and 100Ah capacity, this battery provides reliable power for regular cycling and backup applications. It is suitable for users who need a durable lifepo4 battery pack for practical field use.

3. True Parallel Design with Better Consistency

The battery supports up to 4 units in parallel. With RS-485 communication and active balancing, parallel systems can maintain better consistency and reduce imbalance between batteries, making expansion more reliable.

4. Series Expansion up to 51.2V

For customers building 24V or 48V systems, the battery supports external series connection up to 51.2V. This gives integrators more flexibility when designing different voltage and capacity combinations.

5. Clear OLED Display for Easy Monitoring

A low-power OLED screen shows key battery information such as voltage and SOC, making daily checks more convenient and reducing the need for additional external tools.

6. Durable Structure for Mobile and Field Applications

The battery is equipped with stainless-steel handles for easy handling and transportation. The handle design supports repeated movement and is suitable for RV, camping, marine, and portable power applications.

7. Clear Lifecycle and Warranty Reference

The datasheet provides two reference options:

• 3,500 cycles or 5 years

• 1,500 cycles or 2 years
  Whichever comes first.

This helps buyers and procurement teams match the product with actual operating conditions and project requirements.

Applications

The CFE-1280S Pro is suitable for a wide range of 12V energy storage and backup applications, including:

• RV and camping power systems

• Off-grid solar energy storage

• UPS and telecom backup

• Security and emergency backup power

• Marine auxiliary power systems

• Portable and small ESS applications
