XCELL LFP1250L LiFePO₄ battery with 12.8 V and 50 Ah

The XCELL LFP1250L is a powerful lithium iron phosphate battery (LiFePO₄) that impresses with its 12.8 V nominal voltage and 50 Ah capacity. Thanks to the integrated BMS system and prismatic LiFePO₄ cells, this battery offers maximum safety, long service life and stable performance, even under demanding conditions. The LFP1250L is ideal for industrial energy storage, caravan and marine systems, PV systems and as a reliable replacement for VRLA batteries.

Highlights at a glance

• High performance: 50 Ah capacity at 12.8 V – 640 Wh total energy
• Durable: Over 3000 charge cycles at 80 % depth of discharge (DOD)
• BMS integrated: Protection against overcharging, deep discharge, overtemperature and short circuit
• Robust design: ABS housing, maintenance-free and gas-free
• Fast charging capability: Maximum efficiency with shorter charging times
• Certified: UN38.3, CE and MSDS for tested safety

Powerful in a wide range of applications

The XCELL LFP1250L impresses with an ideal ratio of capacity, size (198 × 166 × 169 mm) and weight (only 6.5 kg). This makes it especially flexible for applications requiring a compact but powerful power source, e.g. in emergency power systems, on-board power supplies for motorhomes and boats, solar storage systems or industrial applications. The reliable cell chemistry ensures stable performance for many years.

Systematic efficiency and safety

The integrated hardware BMS monitors all safety-critical parameters such as voltage, temperature and current in real time. It actively protects the battery against malfunctions and ensures even cell balance. This maximises battery life while enabling safe operation. Parallel connection of up to 2 batteries and series connection of up to 4 batteries is easily possible – ideal for scalable storage systems.

Robust LiFePO₄ technology for increased safety and service life

The prismatic LiFePO₄ cells used offer excellent thermal and chemical stability and particularly low self-discharge. This means the battery is not only safe in daily use but also reliable in the long term. Compared to lead-acid or conventional lithium batteries, LiFePO₄ technology offers a longer cycle life and higher efficiency.
