EcoFlow DELTA Pro 3 Smart Extra Battery

EcoFlow 12V 100Ah Lithium Battery Features

🔋 Core Power & Performance

• High Capacity: 12.8 V, 100 Ah nominal capacity with 1280 Wh energy storage — provides reliable 12 V power for a wide range of DC loads.

• Deep-Cycle LiFePO₄ Cells: Uses LFP battery chemistry for safer operation, long life, and stable performance.

• Long Cycle Life: Rated for ~6000+ cycles at 80 % depth of discharge, far exceeding traditional lead-acid batteries.

• Lightweight & Compact: Significantly lighter and smaller than equivalent lead-acid batteries, making it easier to carry and install.

🔌 Output & Electrical Performance

• Continuous Output: Up to 1280 W continuous power suitable for various DC appliances and inverters.

• Battery Management System (BMS): 100 A X-Guard BMS with advanced protection against over-charge, over-discharge, over-temperature, short-circuit, and over-current — ensuring safe, reliable operation.

• Peak Discharge: Capable of higher surge currents (e.g., up to ~300 A for short durations — depending on regional spec), useful for motor starts or transient loads.

• Expandable Configuration: Can be connected in series or parallel (e.g., 4P4S or 2S8P) to boost capacity and voltage for larger systems.

🔋 Charging & Compatibility

• Versatile Charging: Compatible with solar panels, generators, or grid power — full recharge can take as little as ~2 hours, far faster than lead-acid.

• Recommended Charge Current: Around 50 A for efficient and safe charging, with max continuous charge current up to 100 A.

🌡️ Durability & Safety

• Wide Operating Temps: Performs reliably in temperature ranges from roughly -14 °F to 131 °F (-10 °C to 55 °C) for discharge.

• IP65 Protection: Rugged, water- and dust-resistant casing suitable for outdoor and mobile use.

• Fire-Retardant Shell: Meets stringent safety standards with a self-extinguishing casing to reduce fire risk.

• UL & IEC Certifications: Certified to industry safety standards (e.g., IEC62619, UL1973, CE, FCC, RoHS, UN38.3), ensuring quality and reliability.

⚙️ Design & Practicality

• Standard Terminal Type: Uses sturdy M8 bolts for secure connections.

• Portable Size & Weight: Compact footprint (≈11.4 × 6.9 × 8.7 in) and lightweight (~26.7 lb / ~12.1 kg) make it easy to install in tight spaces — e.g., RVs, boats, solar setups.

• Slot-In Replacement: Can replace Group 27–31 lead-acid batteries in many applications.

Good For: RV and camper power systems, solar battery banks, boating and trolling motors, off-grid workshops, emergency backup, DC appliances, and more — with durability and safety suitable for demanding conditions.
