Trusted by Industry Professionals and Installers
With a proud legacy of 36 years in the industry, now our LiFePO4 batteries have earned widespread adoption across various industries, endorsed by professionals and installers alike. Selling over a million batteries and over 80 Megawatt-hours of energy every year and growing, our track record speaks volumes about our product's reliability and performance.
Unmatched Prismatic Cell Technology
Our larger application LiFePO4 batteries are crafted using state-of-the-art Grade A+ prismatic cells, setting a new standard in battery design. Lighter, safer, and more efficient than the cylindrical cells used by others, our batteries outshine the rest. Our LiFePO4 batteries provide 4000 to 7000 cycles & a 10-year expected lifetime compared to others in the industry. Also supports expansion up to 10 batteries sequenced in parallel at 48V 1000Ah.
Cutting-Edge BMS for Superior Battery Performance
With our proprietary Battery Management System (BMS), precisely optimized to complement our specific cells, you can expect maximum useful life and unparalleled battery protection, ensuring years of uninterrupted enjoyment. Our industry leading built-in Battery Management System (BMS) protects the battery cells from overcharge, deep discharge, overloading, overheating, low-temperatures and short circuits.
Unparalleled Resilience through Rigorous Testing
Our prismatic cells undergo rigorous testing across a multitude of conditions: from puncturing, to fire, short circuit, and even high impact damage, our cells are tested against all types of damage, providing outstanding resilience and the peace of mind you deserve.

ExpertPower 48V 100Ah Lithium LiFePO4 Deep Cycle Rechargeable Battery

Longer Service Life: Our LiFePO4 battery provides 2500 - 7000 cycles & a 10 years lifetime compared to 200 - 500 cycles & a 3 years lifetime in typical Lead Acid chemistry.
Efficient Power: Our LiFePO4 battery’s flat discharge curve holds above 48V for up to 95% of its capacity usage providing astronomical boosts in run-time compared to only 50% in Lead Acid.
Impeccably Lightweight: Our LiFePO4 battery is only a 1/3 of the weight of Lead Acid which makes it the disputable choice for RVs, Marine and Off-Grid Applications when towing or mobility is in the consideration.
Complete Protection: The lithium battery’s unique built-in Battery Management System (BMS) protects it from overcharge, deep discharge, overloading, overheating and short circuit, and excessive low self-discharge rate ensuring up to 1-year maintenance-free storage.
Ironclad Protection: A steel-hardened, gray cast iron case provides significant improvements in protection against structural affects versus a typical plastic case that can have its integrity and functionality compromised by excessive heat and mechanical shock during a typical service-life.
4 in 1 Wiring: The all-purpose PCB regulates current and voltage fluctuation without the need of external balances or additional BMS protections making the battery smart and powerful enough to be utilized in a system of up to 10 batteries in parallel.
Streamlined Visual Assessments: Sophisticated monitoring software provides on-demand information for battery health, cell health, BMS protections, regulatory temperature status, and cell balancing leaving peace of mind and confidence in your system.
Built-in low-temp cut off prevents charging under 23 °F (-5 °C)
