Dr. Prepare LiFePO4 Battery - Your Stronger, Safer and Cleaner Power Solution

Dr. Prepare 12V 100Ah Lithium Iron Phosphate Battery is a safe energy source which offers a greater capacity than other lead acid batteries, with only 1/3 of the weight and size. The integrated BMS protects the battery from various abnormal conditions, so that the battery cells have 3000+ deep cycles and excellent discharge performance.

If you're searching for a deep cycle battery for RV, marine, or off-grid applications, then this lithium-ion battery is the perfect choice for you!


  • Deep Cycle Lithium BatteryDr. Prepare 12V 100Ah Lithium Iron Phosphate battery cells provides 3000+ cycles, which is 6-10 times to lead acid batteries with 300~500 cycles. This battery can help you save money without multiple purchases. Due to its low self-discharge rate (2%), this LiFePO4 battery will be fully ready for operation even after 1 year of storage. This battery can be repeatedly charged and discharged without any memory effect. It can be used no matter what state it is in.
  • Upgraded BMS & Temperature Protection】 The built-in battery management system (BMS) monitors the battery temperature during discharge and charge to protect from various abnormal conditions. Our LFP battery has both high-temperature and low-temperature detection sensors inside the BMS plate. When the temperature is below -4℉ or over 167℉, it will stop discharging. And when the temperature is below 32℉ or over 149℉, it will stop charging. The BMS also can prevent the battery from short circuit, overcharge, overdischarge, overcurrent and so on.
  • Extendible Capacity to PowerThis deep cycle lithium battery enables 1280Wh load power and up to 100A continuous discharge, which can power up most home appliances, such as a fridge, TV, microwave oven, lights, air-conditioner, washing machine, laptop, coffee maker, and more. It also supports to connect up to 4 batteries in series or 4 batteries in parallel to expand power capacity.
  • Lightweight and Powerful】 This Lithium Iron Phosphate battery weighs only 25 lbs, which is only about 1/3 the weight of the lead-acid battery at the same capacity, and it is convenient to carry and use it anywhere. It can run in various systems, including RVs, camper vans, off-grid cabins, home backup power, marine, outdoor emergency power, wind/solar energy storage, and more.
  • High Safety Performance & Environmentally Friendly 】Our LiFePO4 battery is green battery and it doesn't contain any heavy metals and non-toxic materials, which is completely safe to the environment. This battery is compatible with solar panels (not included) to get recharged gradually in sunlight. It can work efficiently in a wide range of temperature while maintaining high capacity. Definitely an ideal replacement for most traditional lead-acid batteries.
  • Best Service】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.

Expand Power Supply Capacity

- Connect your batteries in series (up to 4 batteries) or in parallel (up to 4 batteries) to expand power capacity.

- We recommend connecting batteries with the same capacity (Ah), same type (LiFePO4), and from the same brand. Fully charge the batteries before connection.

Longer Storage Time

The monthly self-discharge rate is as low as 2% when not in use, which means that a fully charged LiFePO4 battery can potentially hold a charge up to 1 year.

Solar Recharging

Compatible with 1000W solar panels (not included) to get recharged gradually in direct sunlight.
