100Ah 48V Wall-Mounted Lithium Battery – For Solar, Wind, and Off-Grid Systems

This compact and powerful 48V 100Ah Lithium Iron Phosphate (LiFePO₄) battery is designed for space-saving wall-mounted energy storage in off-grid, solar, wind, and backup power applications. With high scalability, intelligent management features, and a robust service life, it’s an ideal solution for both residential and commercial systems.

Built with a smart Battery Management System (BMS), this battery ensures safe and efficient operation by monitoring voltage, current, and temperature while protecting against overcharge, over-discharge, short circuits, and extreme temperatures. The system also includes soft start functionality to reduce current surges during inverter activation.

Key Features:

• High Scalability: Up to 15 units can be connected in parallel for large-scale energy storage.
• Long Cycle Life: Delivers up to 6,000 cycles at 95% DoD, ensuring long-term reliability.
• Advanced BMS Protection: Prevents damage from overcharging, deep discharge, temperature extremes, short circuits, and high current.
• Wall-Mounted Design: Includes bracket for secure, vertical installation – ideal for saving space.
• Smart Connectivity: Compatible with Bluetooth and Wi-Fi monitoring via mobile app, supporting CAN and RS485 protocols for integration with leading inverter brands.
• Intelligent Cell Balancing & Current Limiting: Ensures consistent performance across all cells.
• Low Maintenance: Offers more than 10 years of service life with minimal upkeep.

Ideal for:

• Solar and Wind Energy Storage: For off-grid homes, cabins, and small commercial systems.
• Backup Power: Supports critical devices, lighting, and electronics during grid outages.
• Telecom & Networking: Delivers stable energy for communication infrastructure.
• Industrial Use: Supports energy-intensive equipment and automation systems.

Designed for high-efficiency, long-term operation, this 48V lithium battery is the perfect upgrade for energy storage systems where space, reliability, and performance matter.

Warranty

Electrical equipment such as solar charge controllers and inverters have 1 year warranty, unless stated otherwise in our product description. Warranty for our own "Photonic Universe" branded products is provided by Photonic Universe Ltd. If we find any defects in our own products within the warranty period, we will repair or replace such products at our discretion free of charge. Warranty for other products is provided by the product manufacturer and terms and conditions of this warranty might be different from our terms and conditions. Full terms and conditions of the warranty can normally be found in the product manual.

Photonic Universe solar panels are covered by 1 year workmanship warranty in relation to assembly, materials and accessories (connection, cables, diodes, frame etc). In addition, there's a separate performance warranty on solar cells provided by solar cells manufacturers. Most manufacturers of solar cells we use for our solar panels provide the standard industry warranty, which is that solar cells are guaranteed to produce at least 90% of nominal power in 10 years and 80% of nominal power in 25 years.

If you suspect a product defect within the warranty period, please contact us by phone or email with a detailed description of the problem. If the problem cannot be solved remotely and an examination is required, you will be asked to send the item back to us for testing at your cost. If we are involved into repair / replacement of the product and the problem is covered by the warranty, we will return the repaired / replaced item to you at our cost. If the item you sent to us under warranty is in good working condition and no defect is found, it will incur a test service charge and the shipping cost to send the item back to you.
