Specifications
Product Description
The Eleksol Lithium Battery 12.8V 300Ah LFP300BTBA Underseat is a 12.8 V “drop-in” LiFePO₄ battery with a low-profile metal case designed for underseat installations or narrow compartments. It features a BMS with full protections and Bluetooth connectivity to monitor voltage, current, SOC, temperature, and events from your mobile device. Its LFP chemistry ensures high safety, excellent voltage stability, and great charge/discharge efficiency, making it an ideal solution for 12 V solar energy, camper vans, marine applications, golf carts, telecommunications, and UPS/EPS systems.
Main Features
- Safe, maintenance-free LiFePO₄ chemistry with BMS that protects against overcharge, overdischarge, overcurrent, short circuit, and temperature.
- 300 Ah at 12.8 V (≈ 3,840 Wh) with a flat voltage curve and high efficiency (>95%).
- Underseat format: 390 × 360 × 160 mm; approx. weight 33 kg; M8 terminals.
- Integrated Bluetooth for real-time bank diagnostics.
- IP65 protection rating: resistant to dust and water jets (not submersible).
- Compatible in series up to 4 units (≈ 51.2 V) and in parallel with identical units.
Advantages or Benefits
- More usable energy and lower weight than lead-acid at the same Ah: greater autonomy and better Wh/kg ratio.
- Optimized total cost of ownership due to long service life and minimal self-discharge.
- Fast recharge with CC-CV profile and excellent thermal performance.
- Clean “plug & play” installation at 12 V; its low profile makes use of previously unusable spaces.
- App-based monitoring simplifies preventive maintenance and imbalance detection.
Purpose or Applications
Suitable for caravans and camper vans (underseat installation), boats, buggies and golf carts, as well as for 12 V solar storage, telecommunications, control and automation, and UPS/EPS systems. In hybrid systems (PV + alternator), its high efficiency and fast recharge capability allow for frequent cycles with great reliability.
