BLUETTI B4810 — 5120Wh LiFePO4 Battery Module

BLUETTI B4810 — 5,120Wh 48V LiFePO4 Battery Module

The B4810 is the high-capacity 48V LiFePO4 battery module purpose-built for BLUETTI's RV5 power hub and other 48V system installations. With 5,120Wh of LiFePO4 storage, 6,000+ cycle life to 80% capacity (~17 years of typical RV use), and built-in self-heating for cold-weather operation down to -4°F, it's designed for serious RV, off-grid, and home backup builds. IP65 protection means it survives the weather-exposed installations that typical lithium batteries can't handle.
