SkyEnergi Core2 340Ah 12V LiFePO4 Lithium Leisure Battery (Bluetooth & Heated)
Flagship Ultra-High Capacity All-Weather Heated Deep Cycle Lithium Leisure Battery UK
The SkyEnergi Core2 340Ah 12V Lithium Iron Phosphate (LiFePO4) leisure battery is the flagship, maximum-capacity unit in the Core2 range, designed for serious off-grid power systems, off-grid homes, heavy marine craft, and long-term vehicle touring. Delivering a massive 4.35kWh of usable energy from a single casing, it replaces bulky lead-acid battery banks with a single, highly efficient lithium block. Built specifically for extreme UK and European winter conditions, it features an integrated automatic heating pad for sub-zero charging down to -20°C, Grade-A prismatic LiFePO4 cells, a heavy-duty 250A Smart BMS, 4,000+ deep cycles, and built-in Bluetooth app monitoring.
Why choose the SkyEnergi Core2 340Ah Heated Lithium Leisure Battery?
-
Massive 4.35kWh Usable Energy Storage: Delivers an incredible 340Ah nominal capacity (4,352Wh usable energy) in a single housing, dramatically simplifying system wiring and saving space compared to multi-battery banks.
-
Integrated Automatic Internal Heating Pad: Smart thermal management automatically activates the internal heating element when ambient temperatures drop below 0°C, enabling safe battery charging in sub-zero conditions (-20°C to +50°C).
-
Heavy-Duty 250A Continuous Discharge BMS: High-output Smart BMS supports 250A continuous discharge current (500A peak surge for 5 seconds) to comfortably run high-wattage 12V loads and large 3,000W AC inverters for induction hobs, air conditioning, and power tools.
-
Grade-A Prismatic Cell Technology: Built with premium prismatic LiFePO4 cells providing over 4,000 charge/discharge cycles at 80% Depth of Discharge (DoD) for a 10+ year operational service life.
-
Integrated Bluetooth App Monitoring: Wirelessly track live State-of-Charge (SoC %), cell voltages, heating pad status, charge/discharge currents, and internal battery temperature directly via your smartphone.
-
Comprehensive BMS Safety Protections: Complete suite of automated protection against over-charging, over-discharging, over-current, short circuits, high temperatures, and freezing low-temperature charging.
-
Dedicated UK Support: Direct access to Get Green Energy's UK-based technical support team with direct warranty backup.
