Supported by an industry-leading 10-year warranty and lifespan, our Dr.Prepare 12 volt 100Ah LiFePO4 battery is the ideal choice for various applications including RVs, trolling motors, boats, off-grid cabins, and home backup power storage.Enhanced with an upgraded Battery Management System (BMS) and integrated low and high-temperature safeguards, this battery ensures safe and secure operation. Its versatility shines through as it permits the connection of four batteries in series to craft a potent 48V battery bank, or in parallel to assemble an expanded 400Ah battery bank system.Elevate your experience by upgrading from lead-acid to lithium batteries, unlocking a more advanced and refined usage encounter.Description[10-Year Service Life] Dr.Prepare's 12V lithium batteries are accompanied by a 10-year product assurance and service life, a substantial improvement compared to lead-acid batteries which typically offer lifespans of only 1 to 3 years. It's the perfect choice for replacing lead-acid batteries, providing long-lasting durability.[Low-Temperature Cut-Off Protection] The low-temperature cut-off protection ensures the longevity of the battery's health. When the temperature falls within the range of 23â to 41â, the charging process halts. Similarly, when the temperature drops between -13â to 5â, discharging ceases. This feature makes it ideal for use in challenging and demanding environments.[Series and Parallel Connectivity] Our LiFePO4 batteries support series and parallel connections, allowing you to create a 12V, 24V, 36V, or 48V battery bank, or 12V 200Ah, 300Ah, or 400Ah power system. You can even connect up to 16 batteries in series and parallel, building a powerful home backup power system with a 20.48 kWh capacity. [2-3 Times More Power] Dr.Prepare 12 volt lithium batteries offer an impressive power output of 1,280 Wh, surpassing conventional lead-acid batteries of similar size by 2 to 3 times. With a maximum continuous discharge current of 100A, these batteries can power most electronic devices. [Improved BMS Protection] Our upgraded internal BMS expertly manages cell balance, over-current, over-charge, over-discharge, temperature extremes, and short circuits. This refinement leads to enhanced performance and prolonged lifespan. Plus, IP65 dust and water resistance ensures reliable functionality.[Important Reminders]1. Ensure the battery terminals are securely fastened. Loose terminals can lead to heat accumulation and potential battery damage.2. After a full discharge at a continuous 100A, avoid immediate recharging at 50A, as this may trigger high-temperature charging protection.3. Optimal charging involves a 20A current for our lithium-ion battery. While the maximum charging current stands at 50A, exceeding this limit can result in a shortened battery lifespan.Specifications100Ah LiFePO4 Lithium Deep Cycle Battery (S48) - Connect In SeriesTechnical SpecificationsRated Capacity (77°F / 25â) 100AhRated Voltage 12.8VEnergy1280WhCycle Life 3,000 Cycles at 80% DODSelf-discharge Rate (77°F / 25â) 2%~3% / monthMax.
