In stark contrast, traditional lead-acid batteries typically last just about two years, equivalent to a mere 500 cycles at 50% discharge. With a Weize LiFePO4 battery, you can enjoy more than five times the longevity, ultimately reducing your overall cost. Smart Battery Management for Your Peace of Mind: We've integrated a cutting-edge Battery Management System (BMS) into our batteries. This BMS ensures your battery remains safe from overcharge and Discharge, Over-current, Short Circuiting, and extreme temperatures, all while enhancing overall performance and extending battery life. The BMS even features an automatic circuit cutoff, with reactivation in just one second, eliminating the need for a higher voltage input to restart. Lightweight and Versatile for All Your Needs: LiFePO4 batteries are the future of energy storage, offering higher energy density and significantly reduced weight compared to traditional lead-acid batteries. This makes them the ideal upgrade for any 12V Deep Cycle battery. Our batteries are perfect for a wide range of applications, from Fish Finders and Ice Fishing to Camping, Solar Systems, Home Alarm Systems, and E-Scooters. For optimal performance and safety, always charge the battery with a dedicated LITHIUM BATTERY CHARGER, and avoid connecting more than four batteries in series or parallel. Safety First, Environmentally Friendly Always: Crafted from 100% safe, non-toxic, non-hazardous materials, Weize LiFePO4 batteries prioritize safety. Their superior chemical stability ensures they won't overheat, catch fire, or undergo thermal runaway even when punctured. With no acid to worry about, you can confidently mount our batteries in any position. For complete peace of mind, please consult our user manual before use, and don't hesitate to reach out if you have any questions about your battery. Your safety is our top priority.
