Winston Battery 12.8V 100Ah LiFeYPO4 Battery Pack for lead-acid replacement

Ideal Replacement for Lead-Acid Batteries

The Winston Battery 12V 100Ah Lithium Iron Phosphate (LiFePO4) Battery is the ultimate upgrade from traditional lead-acid batteries. Weighing just 37.4 lbs, it is significantly lighter and more compact than conventional options while delivering 3-5 times higher energy density. Engineered to thrive in extreme conditions, it operates flawlessly in temperatures ranging from -45°C to 85°C (-49°F to 185°F), making it resilient against both scorching heat and freezing cold. With robust, stable performance, this battery is the future-forward choice for the new energy era.

Advanced Safety & Low-Temperature Performance
Equipped with a built-in Battery Management System (BMS), this LiFePO4 battery safeguards against overcharging, over-discharging, over-current, and short circuits. Its upgraded low-temperature protection activates at -20°C (-4°F), ensuring reliable operation even in harsh environments. The BMS optimizes performance between -20°C to 65°C (-4°F to 149°F), guaranteeing safety and efficiency in any scenario.

Unmatched Longevity & Cost Efficiency
Designed for heavy-duty use, this battery supports 7,000+ charge-discharge cycles at 70% depth of discharge (DoD), offering a lifespan of up to 20 years. With a self-discharge rate of just 1.5%—far below industry standards—it retains power longer during storage. Its unparalleled durability and low lifetime cost make it the most economical lithium-ion solution on the market.

Eco-Conscious & Certified
Compliant with UL, CE, and RoHS certifications, this battery prioritizes sustainability. It contains no toxic heavy metals and uses eco-friendly materials, including water-based adhesives instead of traditional PVDF. From production to recycling, it aligns with global environmental standards, making it a green energy champion.

Rugged Design for Demanding Applications
Housed in a wear-resistant, IP-rated waterproof casing, the battery withstands tough outdoor conditions. Its internal structure is optimized to resist impact and vibration, ensuring reliability during high-intensity activities. Operating seamlessly from -45°C to 85°C (-49°F to 185°F), it powers everything from marine systems to RV adventures, solar setups, and more.

Upgrade to Innovation
Experience next-generation power with Winston Battery’s LiFePO4 technology—where safety, longevity, and sustainability redefine energy storage. Perfect for automotive, renewable energy, and industrial applications, it’s engineered to outperform, outlast, and inspire confidence.
