Lead-to-Lithium Replacement
12.8V 200AH lithium battery
ALUX high-performance A-Grade LiFePO4 batteries are designed for off-grid solar and backup systems. With a 6000+ cycle life, they perfectly replace SLA batteries. Lightweight and highly efficient, they operate reliably in extreme temps from -45°C to 60°C. Eco-friendly energy storage.
ALUX High-Performance A-Grade LiFePO4 Batteries
Engineered for Solar Off-Grid & Backup Solutions
ALUX rechargeable lithium iron batteries are specifically engineered for solar photovoltaic (PV) off-grid and backup power applications. Featuring an integrated Battery Management System (BMS), these batteries are optimized for fast solar charging and are designed to serve as a direct, drop-in replacement for traditional Sealed Lead Acid (SLA) batteries. With flexible 360-degree mounting options, our batteries maximize space utilization in any enclosure or configuration.
Product Performance and Advantages
- Premium A-Grade Cells: Built exclusively with high-quality A-Grade cells, ensuring superior internal consistency, long-term stability, and maximum safety for your energy storage system.
- Stable Voltage Platform: Maintains a consistent average voltage of 3.7V or 3.2V, providing steady power delivery for critical equipment.
- Ultra-High Energy Density: Achieve significant weight savings; our batteries provide 460-600Wh/kg, weighing only 1/5 to 1/6 of traditional lead-acid products of the same capacity.
- Industry-Leading Cycle Life: Built for long-term reliability, our batteries exceed 6 years of service life and are capable of achieving 10,000 charge-discharge cycles at 1C DOD.
- High-Power Endurance: Designed for demanding applications, our cells support 15~30C high-rate charge/discharge, facilitating high-intensity start-up and acceleration.
- Low Self-Discharge & No Memory Effect: With a monthly self-discharge rate of less than 5%, your battery retains power longer. It features no "memory effect," meaning you can charge it at any time without capacity loss.
- Extreme Thermal Adaptability: Engineered to perform in harsh conditions (-20℃ to 60℃). With our specialized processing technology, these batteries can even operate in extreme cold as low as -45℃.
- High Charging Efficiency: Near 100% current efficiency. The closed-loop design ensures no gas generation during charge or discharge cycles, guaranteeing safety and stability.
- Eco-Friendly Commitment: Designed for sustainability, our batteries are free from toxic heavy metals (such as lead, mercury, and cadmium) during production, use, and disposal.
