The ECELL ELIS1220 represents the next generation of energy storage, packing 256Wh of power into a compact and durable frame. As a high-capacity upgrade in our ELIS series, this 20Ah LiFePO4 battery is specifically designed for applications requiring prolonged backup power and consistent voltage discharge. It serves as a robust, maintenance-free alternative to heavy 20Ah lead-acid batteries, offering a perfect balance between portable weight and industrial-grade performance.
Applications
・Solar Energy Storage: small-scale off-grid solar systems.
・Critical UPS Backup: workstations, and networking gear.
・High-End CCTV: powers multi-camera setups.
・Electric Mobility: electric wheelchairs, golf caddies, electric scooters.
・Outdoor & Marine: perfect for fish finders, camping power kits, medical devices.
・ Exceptional Energy Density：Delivers significantly more power-per-kilogram compared to AGM batteries, providing high energy output without the bulk.
・ Constant Power Delivery：Unlike lead-acid batteries that suffer from voltage drops, the ELIS1220 maintains a steady voltage plateau until nearly exhausted, ensuring your equipment runs at peak efficiency.
・ Rapid Recharge Capability：Supports much higher charging currents, allowing the battery to go from 0% to 100% in a fraction of the time required by traditional systems.
・ Deep Discharge Resilience：Engineered to withstand repeated deep discharge cycles (up to 100% DOD) without damaging the internal cell structure or shortening its lifespan.
・ All-Weather Performance：Optimized for thermal stability, the ELIS1220 operates reliably in a wide temperature range, making it suitable for outdoor solar enclosures and unconditioned utility rooms.
・ Advanced Safety Architecture：Equipped with a precision-tuned BMS that actively balances cells and prevents operational hazards, ensuring total peace of mind for residential and commercial installs.
