In modern off-grid and mobile power applications, energy efficiency, compact design, and reliability are essential. The HHS Slimline 12V LiFePO4 Battery Series offers a perfect combination of advanced lithium technology and ultra-thin construction. Available in 100Ah, 110Ah, 135Ah, and 150Ah, it delivers consistent power for RV, marine, and solar energy storage systems without taking up extra space.
Traditional deep-cycle batteries are bulky and heavy. The HHS Slimline LiFePO4 battery is engineered with an ultra-thin form factor, typically under 75mm in thickness, allowing easy installation in tight compartments, under seats, or wall-mounted systems.
Despite its compact size, it stores up to 1.92kWh of energy (12.8V × 150Ah), enough to power appliances like refrigerators, lights, inverters, and communication devices efficiently. This design maximizes energy density while minimizing weight — ideal for RVs, boats, and off-grid solar setups where every inch of space matters.
Built using Grade-A Lithium Iron Phosphate (LiFePO4) cells, this battery ensures superior thermal stability, chemical safety, and reliability. Unlike lead-acid or ternary lithium batteries, LiFePO4 chemistry provides:
>6000 cycles at 80% DOD, offering more than 10 years of dependable use.
High discharge efficiency (>95%), ensuring minimal energy loss.
Stable voltage output, keeping connected devices protected.
Non-toxic and recyclable materials, promoting a green and sustainable energy solution.
The result is a power system that’s safe, efficient, and built to last.
Every Slimline 12V LiFePO4 battery integrates an advanced 100A Smart BMS, ensuring safe and balanced operation across all cells. The BMS continuously monitors cell voltage, temperature, and current flow, providing automatic protection from:
Overcharge and over-discharge
Overcurrent and short circuit
High and low temperature conditions
Cell imbalance
This ensures the battery remains stable, efficient, and protected in all environments — from freezing mornings to hot engine compartments.
Thanks to lithium technology and intelligent structural design, the HHS Slimline battery weighs less than half of an equivalent lead-acid battery. This not only makes installation easier but also improves fuel efficiency for RVs and boats by reducing overall system weight.
The durable ABS or aluminum case offers protection against vibration, water splashes, and dust, ensuring long-term reliability in mobile and marine applications.
As a true deep-cycle lithium battery, the Slimline 12V LiFePO4 provides full-capacity discharge without damage. Unlike lead-acid batteries that degrade after 300–500 cycles, LiFePO4 maintains over 80% capacity even after 6000 cycles — ensuring long-lasting, consistent energy delivery.
It’s also maintenance-free — no acid, no water filling, no corrosion. Simply charge, connect, and enjoy years of clean power.
The Slimline LiFePO4 series is compatible with a wide range of power setups:
RVs & Camper Vans: Reliable energy for off-grid travel — run your fridge, lights, and inverter all night.
Boats & Yachts: Withstand marine vibrations and humidity while saving valuable cabin space.
Solar Energy Storage: Store solar power efficiently for night use or backup.
Home Backup Power: Provides stable power during grid outages.
Portable & DIY Systems: Lightweight design simplifies installation for custom setups.
Need more capacity or voltage? The Slimline battery supports both parallel and series configurations:
Up to 4 batteries in series (48V system)
Multiple units in parallel to increase capacity
This flexibility makes it perfect for scalable energy systems — from small camping setups to full off-grid solar installations.
HHS LiFePO4 batteries are non-toxic, lead-free, and cobalt-free, ensuring minimal environmental impact. Their high efficiency reduces carbon footprint, making them a sustainable energy choice for eco-conscious users.
