Bluetti B4810 LiFePO₄ Battery - 51.2 V, 100 Ah

BLUETTI B4810 LiFePO₄ Battery 51.2 V 100 Ah

Power your energy setup with a robust, high-capacity lithium battery engineered for reliability, expansion and long life. This premium BLUETTI LiFePO₄ battery is ideal for off-grid systems, RVs, boats, home backup and larger solar energy installs.

High-Capacity Energy Storage for Big Demands

Designed around a 51.2 V, 100 Ah (5,120 Wh) LiFePO₄ battery pack, the B4810 delivers deep-cycle energy that keeps your systems running longer and more efficiently than traditional lead-acid alternatives. With excellent discharge stability and reliable output, it supports heavy loads and extended usage without compromise.

Built for Durability and Long Life

This battery uses advanced LiFePO₄ (lithium iron phosphate) chemistry, giving it a long cycle life of up to 6,000 cycles while retaining 70 % capacity — vastly surpassing typical deep-cycle batteries for longevity and value. The rugged IP65-rated enclosure resists dust and water ingress for reliable performance in diverse environments.

Self-heating technology ensures safe and efficient charging even when ambient temperatures drop below freezing, making it suitable for year-round use in colder climates.

Smart Monitoring and Flexible Expansion

Connect multiple units in parallel or series to scale your energy storage up to massive capacities (over 120 kWh with 24 B4810 modules), giving you the flexibility to grow your system as needs evolve.

Track state of charge, voltage and temperature conveniently via the BLUETTI app using Bluetooth connectivity for real-time insights and peace of mind.
