Description

• 【Much Smaller Size, Same Power】 The Dr.Prepare 12V 100Ah LiFePO4 battery is engineered to be much more compact, saving approx 52% of installation space compared with Group 31 and about 36% compared with Group 24. It’s the perfect fit for tight compartments and mobile energy applications.
  
• 【20+ BMS Protections, Grade A+ Cells, 10-Year Lifespan】 Built with Grade A+ high energy density cells and a smart BMS offering 20+ layers of protection - including low/high temperature cut-off - this deep cycle LiFePO4 battery delivers up to 100A continuous discharge current while maintaining safe and stable performance in a wide range of environments. It’s designed to last, with a 10-year lifespan and reliable product support for long-term peace of mind.
  
• 【Perfect Replacement for Lead-Acid Batteries】Dr.Prepare 12V 100Ah LiFePO4 battery is an ideal upgrade from traditional sealed lead-acid (SLA) batteries. Weighing just 22 lbs, it’s up to 47% smaller and 70% lighter, while offering twice the usable capacity. With a 10-year lifespan- compared to just 1-3 years for most SLA batteries - it significantly reduces replacement frequency and long-term costs. Plus, it supports side mounting, giving you more flexibility in installation.
  
• 【Safe Charging & Discharging】 Use a compatible AC-to-DC LiFePO4 charger or a solar panel system with a charge controller set to the LiFePO4 battery type. Do not use general-purpose or lead-acid battery chargers. Recommended charging current: 20A (Max: 50A). Maximum continuous discharge current: 100A. After a full 100A discharge, avoid immediately recharging at 50A, as it may trigger the battery’s high-temp charging protection.
  
• 【Series & Parallel Connections】 Dr.Prepare LiFePO4 battery supports both series and parallel configurations. Easily build a 24V, 36V, or 48V system using series connections. Expand capacity to 12V 200Ah, 300Ah, or 400Ah with parallel connections. Supports up to 16 batteries in a combined series-parallel setup, ideal for home backup systems. For any configuration, all connected batteries must be the same model. NOT suitable for use as a car starter battery or for cranking boat engines.
