Eleksol Lithium Battery 12.8V 400Ah LFP400AHBT Bluetooth

Product Description

The Eleksol Lithium Battery 12.8V 400Ah LFP400AHBT Bluetooth is a high-capacity LiFePO₄ (lithium iron phosphate) accumulator designed as a “drop-in” replacement for 12 V lead-acid batteries. It incorporates a BMS with full protections and Bluetooth connectivity to view the state of charge (SOC), voltage, current, temperature, and events from the app. With 5,120 Wh of nominal energy, an ABS enclosure with IP65 protection, and low self-discharge, it offers safety, fast recharging, and a lifespan exceeding 3,000 cycles, making it ideal for solar energy, marine, caravanning, telecommunications, and industrial applications.

Main Features

• Safe, stable, and maintenance-free LiFePO₄ (LFP) chemistry, with BMS that protects against overcharge, overdischarge, overcurrent, short circuit, and temperature.
• 400 Ah at 12.8 V (≈ 5,120 Wh) with a flat voltage curve and high efficiency (>95% typical).
• Integrated Bluetooth for real-time monitoring and bank diagnostics.
• IP65 protection rating: resistant to dust and water jets (not submersible); self-discharge < 3%/month.
• 12 V “drop-in” format with M8 terminals and robust ABS enclosure (≈ 38 kg).
• Series connection up to 4 units (≈ 51.2 V) and parallel connection between identical units following best practices.

Advantages or Benefits

• More usable energy and much less weight than AGM/Gel at the same Ah: greater autonomy and better Wh/kg ratio.
• Optimized total cost of ownership thanks to >3,000 cycles @80% DoD and its high coulombic efficiency.
• Fast recharge with CC-CV profile, ideal for short charging windows in marine, camper, or hybrid PV+alternator applications.
• Clean operation: zero maintenance, minimal self-discharge, and superior thermal stability.
• Control and prevention: the Bluetooth app facilitates preventive maintenance and imbalance detection.

Purpose or Applications

Recommended for 12 V solar storage (off-grid homes, technical cabins), boats and caravans/campers, UPS/EPS, golf carts/buggies, telecommunications, and control/automation systems. Also suitable for cyclic applications with frequent charge and discharge where safety, continuous power, and rapid charge replenishment are required.

Technical Specifications

Compatibilities

Compatible with 12 V solar charge controllers (PWM/MPPT) that have a LiFePO₄ profile or adjustable voltages (CV 14.6 V). Works with dedicated AC chargers for lithium (CC-CV) and with alternators via DC-DC chargers to limit voltage and current. Suitable for 12 V pure sine wave inverters according to the bank’s capacity: comfortable operation ≈ 1.28 kW DC per battery (up to ≈ 3.2 kW DC at maximum continuous under favorable conditions). Can be connected in series up to 4 units for 24/36/48 V and in parallel between identical LFP400AHBT units (pre-match voltage, symmetrical wiring, and fuse per battery).

Eleksol Lithium Battery 12.8V 400Ah LFP400AHBT Bluetooth is a professional solution for demanding renewable energy projects: it increases autonomy, reduces maintenance, and improves the overall efficiency of your installation.
