One of the biggest challenges in mobile or marine environments is limited space. The ultra-thin structure of this 12V 200Ah battery (less than 3 inches thick, depending on model) makes it ideal for installations where traditional batteries cannot fit. Despite its compact footprint, it delivers an impressive 2.56kWh of usable energy, enough to power your essential devices and appliances for hours — whether you’re cruising offshore, camping in the wild, or driving across the country in your RV.
This battery is built with premium Lithium Iron Phosphate (LiFePO4) cells, known for their exceptional safety, stability, and longevity. Compared to lead-acid and ternary lithium batteries, LiFePO4 offers several key advantages:
Longer lifespan: Over 6000 deep cycles at 80% DOD, lasting up to 10 years or more.
Higher efficiency: Charge and discharge efficiency above 95%, minimizing energy loss.
Superior thermal stability: No risk of fire or explosion under normal operation.
Environmentally friendly: Non-toxic materials and fully recyclable structure.
Safety and performance are guaranteed through a built-in 100A Smart Battery Management System (BMS). This intelligent control system continuously monitors every cell’s voltage, temperature, and current, ensuring your battery always operates within safe limits.
BMS Protections include:
Overcharge / Over-discharge protection
Overcurrent protection
Short-circuit protection
Over-temperature and low-temperature cut-off
Cell balancing for stable performance and extended cycle life
Whether you are charging through solar panels, an alternator, or a shore power system, the Smart BMS keeps your battery protected and efficient at all times.
The HHS 12V 200Ah Ultra-Thin LiFePO4 Battery is suitable for multiple scenarios and energy systems:
RV Power System: Run lights, fridges, water pumps, and inverters on long road trips.
Camping Energy Storage: Power your cooking gear, coolers, and electronics off-grid.
Marine & Yacht Applications: Designed to handle vibration, humidity, and confined spaces.
Solar Energy Storage: Works seamlessly with solar panels for renewable, off-grid systems.
Backup Power: A dependable emergency power solution for homes or mobile workstations.
This battery is also compatible with parallel or series connections — allowing users to expand capacity (up to 48V systems) for larger setups.
Unlike traditional batteries that lose efficiency after a few hundred cycles, this LiFePO4 battery maintains over 80% capacity even after 6000+ charge-discharge cycles. It’s a true deep-cycle battery, built to handle continuous charge and discharge operations without degradation.
It can safely provide 100A continuous discharge current, ensuring stable output for high-power devices such as inverters, motors, and marine equipment.
Weighing approximately half of a comparable lead-acid battery, this 12V 200Ah model simplifies transport and installation. There’s no acid, no fumes, and no maintenance — simply charge and use. Its solid aluminum or ABS case ensures long-term durability, even in harsh outdoor environments.
HHS ENERGY’s LiFePO4 batteries are environmentally responsible, using recyclable materials and generating minimal carbon footprint throughout their lifecycle. The high energy efficiency (>95%) ensures every charge counts, reducing waste and saving energy costs over time.
