I. Product Overview

Introducing the EVE LiFePO4 Battery, a cutting-edge Lithium Iron Phosphate (LFP) energy storage solution engineered for reliability and versatility. Boasting over 1500 charge - discharge cycles, this brand - new battery delivers exceptional performance across diverse applications. With low internal resistance, an extended service life, and a wide temperature tolerance, it powers everything from personal mobility devices to marine equipment. Whether you’re upgrading your motorcycle’s power system or building a solar energy storage setup, the EVE LiFePO4 Battery ensures consistent, long - lasting energy to keep your devices running smoothly.

II. Product Parameters and Specifications

Core Technical Data

  • Model: EVE C40

  • Rated Capacity: 20Ah (provides ample energy for sustained operation of mid - power devices like electric scooters, golf carts, and small solar setups).

  • Nominal Voltage: 3.2V (stable output ensures compatibility with standard 3.2V LFP systems, delivering reliable power for electronics and vehicles).

  • Charge Voltage: 3.65V (optimized for efficient charging, minimizing downtime and maximizing energy retention).

  • Internal Resistance: ≤1.9mΩ (low resistance reduces energy loss during charge/discharge, enhancing overall system efficiency).

  • Cycle Life: 1500+ Cycles (outlasts many traditional battery chemistries, lowering long - term replacement costs and environmental impact).

Physical Dimensions & Weight

  • Dimensions: 40.8*135.5mm (compact cylindrical design fits seamlessly into tight spaces, ideal for mobility devices, marine applications, and modular energy systems).

  • Weight: 366±6g (lightweight construction simplifies installation and reduces payload in portable or vehicle - mounted setups).

III. Standard Configuration and Core Components

Core Components

  • LFP (Lithium Iron Phosphate) Cell: The heart of the battery, leveraging LFP chemistry for superior safety, thermal stability, and long cycle life. Unlike other lithium chemistries, LFP is resistant to thermal runaway, making it ideal for high - reliability applications.

  • Optimized Electrodes: Engineered for efficient electron transfer, these electrodes enable rapid charging and stable discharging. They ensure consistent power delivery even under high - demand conditions (e.g., accelerating a motorcycle or powering a solar system at night).

  • Safety - Enhanced Design: Built - in safeguards protect against overcharging, over - discharging, and short circuits. This ensures the battery operates safely across its entire lifespan, even in extreme environments.

IV. Product Advantages

1. Exceptional Durability & Longevity

  • 1500+ Cycle Life: Designed to withstand repeated charge - discharge cycles, this battery outperforms lead - acid and even some lithium - ion alternatives. It’s a cost - effective choice for applications requiring frequent cycling, such as solar energy storage or daily - use mobility devices.

  • Wide Temperature Range: Operates reliably in harsh conditions, from cold winters to hot summers. This makes it suitable for outdoor applications like marine vessels, golf carts, and off - grid solar setups, where temperature fluctuations are common.

2. High Efficiency & Performance

  • Low Internal Resistance: Minimizes energy loss during charging and discharging, ensuring more of the stored energy reaches your devices. This efficiency is critical for maximizing the range of electric vehicles (e.g., motorcycles, scooters) and the output of solar storage systems.

  • Stable Voltage Output: Maintains a consistent 3.2V nominal voltage, preventing power fluctuations that can damage sensitive electronics or reduce vehicle performance.

3. Versatile Applications

  • Mobility Devices: Powers motorcycles, electric scooters, golf carts, and mobility scooters. Its compact size and lightweight design make it easy to integrate into existing systems, while its long cycle life reduces maintenance.

  • Renewable Energy Storage: Stores excess energy from solar panels for use during low - generation periods (e.g., nights, cloudy days). This reduces reliance on the grid and lowers energy costs for homes or small businesses.

  • Marine & Recreational Use: Ideal for powering marine electronics, trolling motors, and RV appliances. Its resistance to temperature extremes and vibration ensures reliable performance on the water or on the road.

4. Safety & Reliability

  • LFP Chemistry: Inherently safer than other lithium chemistries, with no risk of thermal runaway or hazardous leaks. This makes it a trusted choice for applications where safety is paramount (e.g., personal mobility, residential energy storage).

  • Rigorous Testing: Built to meet high - quality standards, ensuring consistent performance and durability. Each battery undergoes strict quality checks to deliver a reliable power solution you can count on.


Upgrade to the EVE 20Ah LiFePO4 Battery for a safer, more efficient, and longer - lasting energy solution. Whether you’re powering your daily commute, off - grid adventures, or renewable energy systems, this battery delivers the performance and reliability you need. Trust EVE’s expertise in energy storage to keep your devices running strong, cycle after cycle.
