YABO LF4020 12V 12Ah LiFePO4 Battery

Rechargeable Deep Cycle Lithium Iron Phosphate Battery for Solar & Energy Storage Systems

The YABO LF4020 12V 12Ah LiFePO4 Battery is a high-efficiency, deep-cycle lithium battery designed for reliable, long-term energy storage. Built with advanced Lithium Iron Phosphate (LiFePO4) chemistry and an integrated smart Battery Management System (BMS), this battery delivers exceptional safety, durability, and performance for a wide range of 12V applications, especially solar systems, off-grid power solutions, and portable energy equipment.

Engineered as a modern replacement for traditional lead-acid batteries, the YABO LF4020 provides longer service life, higher usable capacity, lighter weight, and maintenance-free operation—making it a smart and cost-effective power solution for both consumer and professional users.

It is better to use the 14.6V LiFePO4 battery charger to charge. It should be noted that the cell would be possible to be at a over-discharged state by its self-discharge characteristics in case the cell is not used for long time. In order to prevent over-discharging, the cell shall be charged periodically to maintain between 12V and 13.8V. Over-discharging may causes loss of cell performance, characteristics, or battery functions.

Advanced LiFePO4 Technology for Maximum Safety

At the heart of the YABO LF4020 is Lithium Iron Phosphate (LiFePO4) chemistry, widely recognized as one of the safest and most stable lithium battery technologies available today. Compared with conventional lithium-ion and lead-acid batteries, LiFePO4 batteries offer superior thermal stability and chemical resistance.

Key benefits of LiFePO4 chemistry include:

• Excellent thermal stability with minimal risk of overheating
• No explosion or combustion under normal operating conditions
• Stable voltage output throughout discharge
• Low self-discharge rate for long shelf life
• No memory effect

These characteristics make the YABO LF4020 especially suitable for solar energy systems and critical power applications where safety and reliability are essential.

Built-In Smart BMS Protection

The YABO LF4020 is equipped with an intelligent Battery Management System (BMS) that continuously monitors battery status and ensures safe operation under various conditions.

The built-in BMS provides comprehensive protection against

• Overcharge
• Over-discharge
• Overcurrent
• Short circuit
• Over-temperature

This smart protection system safeguards both the battery and connected devices, ensuring stable performance and extending overall battery life.

Wide Operating Temperature Range
The YABO LF4020 is engineered to perform reliably in a wide range of environmental conditions, making it suitable for solar and outdoor applications.

• Discharge Temperature Range: -20°C to 60°C
• Charge Temperature Range: 0°C to 45°C

This broad operating range ensures stable performance in cold winters and hot summers alike.

Durable Housing and High-Quality Construction

The battery is enclosed in a high-strength, non-conductive ABS plastic housing, designed to withstand vibration, shock, and heat. This rugged casing protects the internal prismatic LiFePO4 cells and ensures long-term durability in both indoor and outdoor environments.

Inside, the cells are carefully assembled with secure internal connections and insulation, while the exterior terminals provide reliable electrical contact and excellent conductivity for efficient power transfer.

Ideal for Solar and Energy Storage Systems

With stable voltage output, long cycle life, and deep-cycle capability, the YABO LF4020 is an excellent choice for solar energy storage systems. It efficiently stores energy generated by solar panels and delivers consistent power when needed, improving overall system efficiency and reliability.
