Dr. Prepare LiFePO4 Battery - Your Stronger, Safer and Cleaner Power Solution
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.
- 【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 23℉ to 41℉, the charging process halts. Similarly, when the temperature drops between -13℉ to 5℉, 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.
- 4. Dr. Prepare batteries will be shipped from California, USA. We provide 10-year battery warranty and lifetime technical support, if you have any questions during usage, please feel free to contact us.
