Compact. Powerful. Reliable.
Our New Slimline 12V LiFePO4 Battery Series is specially designed for users who need maximum power in limited space. With capacities ranging from 100Ah to 500Ah, these ultra-thin, high-performance lithium batteries are ideal for RVs, marine systems, home solar storage, off-grid power setups, and portable energy stations.
Unlike bulky lead-acid or AGM batteries, our slimline LiFePO4 design combines lightweight construction, longer lifespan, and high energy density — delivering powerful deep-cycle performance that fits seamlessly into narrow spaces like RV compartments or under seats.

| ≥500PCS | $122.37/Pcs |
Engineered with a slim, rectangular form factor, this battery fits easily in tight compartments — perfect for RV battery boxes, boat cabins, and wall-mounted solar systems. Despite its compact design, it still offers high-capacity power up to 500Ah.
Utilizing LiFePO4 (Lithium Iron Phosphate) chemistry, these batteries can handle 4000–6000 full charge/discharge cycles, maintaining 80%+ capacity after years of heavy use. Ideal for continuous deep-cycle applications.
Compared with traditional lead-acid batteries that last 2–3 years, our LiFePO4 batteries deliver over 10 years of service life, ensuring lower replacement and maintenance costs.
Each slimline battery includes a smart Battery Management System (BMS) that monitors and safeguards performance:
Overcharge and over-discharge protection
Overcurrent and short-circuit protection
High and low temperature protection
Automatic cell balancing
This ensures stable operation, safety, and long-term reliability in various environments.
Our batteries weigh roughly one-third of comparable lead-acid batteries, yet provide double the usable energy. For example, a 12V 300Ah LiFePO4 battery offers over 3800Wh of usable power — perfect for energy-demanding systems without adding extra weight.
Supports fast charging up to 14.6V using standard lithium chargers. With >95% charge efficiency, energy is stored and released with minimal loss, maximizing every watt from solar panels or alternators.
No acid, no gas, and no maintenance required. LiFePO4 is a non-toxic, stable, and environmentally friendly chemistry that’s safe to use indoors or outdoors.
RVs & Camper Vans: Ideal for onboard electronics, fridges, lighting, and air conditioning.
Marine & Boats: Withstands humidity, vibration, and temperature variations.
Home Solar Storage: Provides clean, efficient backup power for daily household use.
Camping & Off-Grid: Compact and lightweight energy for outdoor adventures.
Industrial or Emergency Backup: Reliable power when grid electricity is unavailable.
