The ECELL ELIS1250 is a powerhouse designed for users who require substantial energy autonomy. With a massive 640Wh capacity, this 50Ah Lithium Iron Phosphate battery is the professional’s choice for scaling up power systems. Whether you are managing a remote telecommunications site or a residential solar array, the ELIS1250 offers the perfect intersection of high-capacity storage and the safety of LiFePO4 chemistry, effectively replacing bulky, heavy-duty lead-acid banks.
Applications
・Off-Grid Solar Stations: Perfect for powering remote monitoring stations.
・Marine & RV Power: Reliable house battery for caravans, motorhomes.
・Telecommunications: Robust backup power for cellular towers.
・Professional Surveillance: Supports large-scale CCTV networks with multiple cameras.
・Industrial UPS: Provides deep-cycle backup for medical equipment.
・ Scalable Energy Storage: Designed with parallel-readiness in mind, allowing users to easily expand their capacity for larger 12V system requirements.
・ Low Self-Discharge Rate: Features advanced cell chemistry that retains its charge for months, making it the perfect choice for seasonal equipment or emergency standby power.
・ Stable Power Curve: Experience consistent performance with a flat discharge profile, ensuring your high-drain devices receive the same power at 10% charge as they do at 100%.
・ Superior Thermal Resilience: Built to endure rigorous environments, its internal architecture dissipates heat efficiently, preventing performance degradation in warmer climates.
・ Maintenance-Free Autonomy: Eliminates the need for “watering” or terminal cleaning associated with flooded batteries, offering a “set and forget” solution for remote installations.
・ Intelligent Cell Balancing: The integrated BMS doesn’t just protect; it actively balances the internal cells to prolong the overall health and capacity of the battery pack.
