Skyenergi Core2 – Power Without Limits
Meet the Skyenergi Core2, the ultimate breakthrough in portable energy solutions. Built for those who demand uncompromising reliability and innovation, this battery is powered by a cutting-edge 200A JBD BMS—the most advanced leisure battery management system on the market.
Optimised for Under-Seat Installation
This isn’t just any lithium battery — it’s specifically designed to fit in the seat base of your vehicle. (Ducato, Relay, Boxer, VW T6.1, T7, New Ford Custom, Mercedes Sprinter, MAN-TGE)
✔ Saves valuable floor or storage space
✔ Keeps weight low and central for better handling
✔ Looks clean and factory-style under the captain’s seat
No awkward battery boxes cluttering your living area — just neat, integrated storage.
Large Usable Capacity (230Ah)
With its impressive 230Ah capacity (approx. 2,944 Wh usable energy), it will reliably power:
12 V fridge/freezer
LED lighting
Water pump
USB and 230 V inverters
Fans, heaters, and small appliances
and even a 2kW inverter
That’s enough to comfortably handle extended weekend trips off-grid without draining your battery prematurely.
Lithium Performance (LiFePO₄)
Compared to lead-acid (wet/flooded, AGM, gel, etc.):
Much deeper usable capacity – ~80–100% discharge vs ~50%
Faster charging – from solar, alternator or mains
Long lifespan – typically 6,000 cycles (years of reliability)
Low self-discharge – holds charge better when parked up
In real terms: more power, more cycles, less weight, and less hassle.
Built-In Smart Protection (BMS)
This battery includes a quality Battery Management System (BMS) that protects against:
Over-charge
Over-discharge
Short-circuit
Over-current
High/low temperature
The result? Greater safety and peace of mind when powering valuable electronics on the road.
Bluetooth Monitoring
With Bluetooth, you can:
Check state of charge (SoC) on your phone
Track voltage and current
Monitor historical performance
Diagnose issues before they become problems
It’s like having a diagnostics screen right in your pocket.
Lighter & Less Maintenance Than Lead Acid
Much lighter than equivalent lead-acid batteries → more payload for gear
Zero maintenance (no watering or equalising)
Better performance in everyday use
More usable power (over 50%) than Lead acid and AGM batteries.
That equals more freedom and less fiddling when you’re out adventuring.
Better in Colder Conditions
Include heat pads & temperature management, which helps the battery:
Charge better in winter
Stay healthier in colder climates
That’s a sweet bonus if you like touring in colder climates.
Clean, Integrated Aesthetics
Because the battery is designed as a seat base replacement, installs look professional and tidy — no bulky boxes behind seats or in awkward spots.
Great for resale value and overall finish.
In Summary — Why Buy It
You should choose a SkyEnergi 230Ah Seat Base Lithium Battery if you want:
A high-capacity battery that actually fits neatly in your leisure vehicle
Longer life and better cycle performance than lead acid
Lightweight and high efficiency for off-grid reliability
Modern smart features and built-in protection
A cleaner, more professional install under your seat
Specification
We Accept

Cold Protection
Our Core and Elite ranges are built with integrated heat pads, ensuring reliable charging even in extreme temperatures. Unlike some brands, our advanced heat pad technology is placed between every cell, maintaining a consistent temperature across the entire battery for optimal charging performance and longer life expectancy.
Please note: that some brands emphasis that their batteries have "Low Temperature Protect". Like our Edge range the majority of lithium batteries have this feature. Which basically means that if the battery falls below a set temperature it will turn off for protection. Batteries with heat pads will continue to operate in adverse conditions.
Victron Integration
Our Elite range is equipped with advanced CAN-Bus technology, enabling seamless integration with Victron Energy’s suite of CAN-Bus active solutions. This direct communication link ensures full compatibility with Victron’s monitoring and management systems, giving you precise control over your battery’s charging and discharging operations. By connecting directly to Victron services, users benefit from real-time data, enhanced system efficiency, and smarter energy management — ensuring optimal performance and reliability in every application.
High Quality Cells
All our SkyEnergi leisure batteries are manufactured to the highest standards, combining precision engineering with rigorous quality control at every stage of production. We use only world-leading lithium iron phosphate (LiFePO₄) cells, carefully selected for their exceptional reliability, performance, and safety.
Each battery is built to deliver outstanding cycle life, providing thousands of charge and discharge cycles while maintaining consistent capacity and efficiency. This ensures long-term durability and dependable power, even under demanding conditions.
How long can I stay off grid?
A question we get asked many times. So we've created a simple calculator to give you some idea of how long your battery will last off grid. It will take into consideration any solar panels you've installed, 12v and 240v usage. Based on the information provided it will recommend a battery size and estimate the number of days use.
