VOLT POLSKA LiFePO4 12V 50Ah 50A litium-rautafosfaatti akku

Unlike standard lead-acid batteries that fade after a few hundred cycles, this LiFePO4 unit delivers over 2000 cycles at 80% depth of discharge, making it a long-term power solution for demanding applications. Its built-in Battery Management System (BMS) actively protects against overcharge, over-discharge, overcurrent, short circuits, and extreme temperatures, ensuring safe and reliable operation in solar setups, electric vehicles, and backup systems.

Highlights

• Lithium Iron Phosphate (LiFePO4) chemistry for superior safety and longevity
• Nominal voltage 12.8V, capacity 50Ah, energy 640Wh
• Max continuous discharge current 50A, max charge current 50A
• Built-in BMS with multiple protections
• M8 screw terminals for secure connections
• Supports series (up to 4) and parallel (up to 4) connections
• Wide operating temperature range: -20°C to 60°C (discharge)
• ABS plastic housing for durability

In daily use

Powering a solar energy system, an electric vehicle, or a backup power supply, this battery delivers consistent performance. Its high round-trip efficiency (>99%) ensures minimal energy loss, while the low self-discharge rate (<3% per month) keeps it ready when needed. The BMS actively monitors cell voltages and temperatures, automatically disconnecting the battery under fault conditions to protect both the battery and your equipment.
