Description

• 10-Year Lifespan & Built-in BMS
  Our Dr.Prepare 100Ah LiFePO4 battery offers a 10-year product support and lifespan. The advanced built-in BMS system provides 20+ layers of protection — including low- and high-temperature cut-off — to protect the battery during charging and discharging, even under extreme conditions. Plus, all internal battery cells are UL-tested and certified to ensure maximum safety and reliability.
• Upgrade to Dr.Prepare LiFePO4 Batteries
  Dr.Prepare lithium batteries outperform traditional lead-acid batteries with a longer lifespan of up to 10 years, compared to just 1–3 years for most SLA options. Weighing only 22 lbs, this 12V LiFePO4 battery is lighter and delivers more consistent power than standard SLA batteries. Plus, it features an integrated BMS for enhanced safety — a level of protection SLA batteries simply don’t offer.
• Series & Parallel Connections for Powerful Backup Power
  Dr.Prepare 12V 100Ah lithium battery supports both series and parallel configurations. Easily build a 24V, 36V, or 48V battery bank with series wiring, or expand your capacity to 12V 200Ah, 300Ah, or 400Ah through parallel connections. For larger setups, you can link up to 16 batteries in series and parallel to create a powerful 20.48 kWh home backup system—ideal for power outages or hurricane season.
• Real-Time Monitoring & Applications
  The built-in LED display provides real-time updates on power capacity, voltage, and charging/discharging current — eliminating guesswork, staying powered with confidence. Ideal for RVs, trailers, trolling motors, boats, off-grid cabins, and home backup power during outages or hurricane season.
• Trolling Motor Usage & Charging Tips
  When using the battery with a trolling motor, we highly recommend installing a circuit breaker (60A to 100A) between the battery and your device to prevent overdischarging. The optimal charging current is 20A (max 50A). To recharge, use a compatible AC to DC LiFePO4 battery charger or a solar panel system with a charge controller to ensure safe and efficient charging.
• 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 battery. While the maximum charging current stands at 50A, exceeding this limit can result in a shortened battery lifespan.
• 4. How to Calibrate Screen Display:
      1) Discharge the battery to 0%.
      2) Use a compatible LiFePO4 battery charger or solar charge controller to fully charge the battery.
