DYNESS 25.6V 100AH DL2.5 Features

High-Quality Lithium Storage

• LiFePO₄ (Lithium Iron Phosphate) chemistry — safe, thermally stable, and long-lasting compared with traditional lead-acid batteries.

• Nominal Capacity: 100 Ah at 25.6 V, equating to ~2.56 kWh of usable energy.

• Depth of Discharge (DOD): High usable energy with ~90–95 % DOD for efficient daily use.

Performance & Power

• 1.3C Discharge Rate: Supports higher discharge for powering multiple loads without strain.

• Recommended/Max Currents: Typically ~50 A recommended charge/discharge with peaks up to ~130 A for short bursts (≈30 min).

• Fast Charge Capability: Can handle up to ~75 A charge current for efficient recharging.

Modular & Expandable

• Parallel Expansion: Up to 16 DL2.5 units can be connected in parallel, scaling total storage from ~2.56 kWh up to ~40.96 kWh for larger systems.

• Flexible Installation: Compact design supports wall-mounted or floor-standing setups.

Intelligent Battery Management

• Integrated BMS: Protects against over-charge, over-discharge, over-current, abnormal temperature, and short circuits.

• Cell Balancing: Automatic balancing for enhanced performance and longer battery life.

• Communication Options: CAN / RS485 and optional Wi-Fi monitoring for integration with inverters and energy management systems.

Durability & Safety

• Long Cycle Life: Rated for ≥6000 cycles, translating to many years of reliable operation.

• Safe Operation Range: Operates across wide ambient temps — charging 0 °C to +55 °C and discharging −20 °C to +55 °C.

• IP20 Protection: Indoor-rated design suitable for typical residential or small commercial installations.

Design & Installation

• Compact Dimensions: ~481 × 221 × 133 mm — compact footprint for easier placement.

• Weight: ~23 kg — relatively lightweight for its capacity and easy to handle.

• Efficient Space Use: Reduced volume compared with older battery tech, making installation simpler.

Ideal For

✔ Residential solar energy storage — stores excess solar generation for nighttime or backup use.
✔ Backup power systems — keeps essential circuits running during outages.
✔ Off-grid or hybrid applications — pairs with inverters for off-grid energy independence.
✔ Scalable energy systems — grow your battery bank by adding more DL2.5 units.
