๐Ÿ“‹Product Details from Amazon
  • [Compact Size, True 300Ah & 3,840Wh] Measuring 15.16โ€ (L) ร— 7.68โ€ (W) ร— 10.24โ€ (H), including side handles terminals, this compact 12V 300Ah LiFePO4 battery delivers 3ร— the energy of a standard 100Ah batteryโ€”without taking up 3ร— the space. With a true-rated capacity of 3,840Wh, it provides longer-lasting power for your appliances. Backed by a 10-year lifespan and product support, Dr.Prepare 300Ah LiFePO4 battery is built for performance you can count on.
  • [Grade A+ High Density Cells, 200A BMS with Low Temp Cut Off] Dr.Prepare 12V 300Ah LiFePO4 Battery is built with Grade A+ high energy density cells for stable, long-lasting power. With a robust 200A continuous discharge rate, this lithium battery easily handles high-power appliances. Advanced BMS offers full protection against overcharge, over-discharge, short circuits, and low/high temperature.
  • [Upgrade to Dr.Prepare LiFePO4 Batteries] Dr.Prepare lithium batteries offer a major upgrade over traditional SLA batteries โ€” lasting up to 10 years, compared to just 1โ€“3 years for most SLA options. Weighing only 57 lbs, this 12V 300Ah LiFePO4 battery is 70% lighter than three 100Ah SLA batteries combined, while delivering more consistent and reliable power. It also features a built-in 200A BMS for advanced protection โ€” something SLA batteries simply canโ€™t match.
  • [Series & Parallel Ready, Scalable Power Expansion] Supports both series and parallel configurations. Build a 24V, 36V, or 48V battery bank with series wiring, or expand to 12V 600Ah, 900Ah, or 1200Ah with parallel connections. Link up to 16 batteries (4P4S) to create a powerful 61.44kWh home backup systemโ€”perfect for outages, hurricane season, or running high-demand appliances.
  • [Charging & Discharging] Supports solar charging (must be used with a charge controller) and compatible AC-to-DC LiFePO4 battery chargers. Do not use general-purpose or SLA chargers, as they may cause damage. Optimal charging current: 60A (max: 100A). Max continuous discharge current: 200A.
  • [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 200A, avoid immediate recharging at 100A, as this may trigger high-temperature charging protection. 3. Optimal charging involves a 60A current for this lithium battery. While the maximum charging current stands at 100A, exceeding this limit can result in a shortened battery lifespan.
