Built for Endurance – A Battery that Lasts
Embark on a journey of sustained power with our LiFePO4 battery, designed to thrive through over 2000 cycles at 100% discharge or an astounding 8000 cycles at 50% depth of discharge (Suggested) – all while maintaining peak performance. Bid farewell to the limited lifespan of traditional lead-acid batteries, as our LiFePO4 battery lasts an incredible 10 times longer, leading to substantial cost savings. Plus, with its cold weather protection, this battery defies all odds even in the harshest weather conditions.
Advanced Protection with 100A BMS
Experience seamless power management with our innovative Automatic Battery Management System (BMS). Safeguarding your battery against overcharge, Discharge, Over-current, short-circuiting, and Low and High Temperatures, the BMS ensures optimal performance and extended life. Watch as the BMS automatically cuts off the battery, with effortless reactivation taking just 1 second, eliminating the need for higher voltage input.
Say Goodbye to Power Shortages
Each 51.2V 100Ah LiFePO4 battery packs 5.12 kWh of reliable energy. Connect up to 10 in parallel to build a massive 51.2V 1000Ah system with an incredible 51.2 kWh of total capacity. Whether for home backup, off-grid living, or heavy-duty applications, this powerhouse system effortlessly meets even the most demanding energy needs. Install it once — and enjoy uninterrupted power for years to come.
Temperature-Protected LiFePO4 Battery
Keep your battery protected year-round with this advanced feature. Designed with a low-temperature cut-off, it automatically stops charging below 32°F, preventing potential damage. When temperatures rise above 41°F, charging seamlessly resumes. For added protection, the battery also halts discharge below -4°F, ensuring reliable performance in extreme cold.
