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.
