Experience the Power of Unmatched Reliability - Weize 10-Year Warranty on LiFePO4 Batteries!

The WEIZE 12V 200Ah 2560Wh Heated LiFePO4 Lithium Battery is a high-capacity rechargeable battery designed primarily for applications that require reliable, long-lasting power, such as RVs, boats, solar power systems, and other off-grid energy systems. Here's a breakdown of what makes this battery special:

Key Features:

  1. 12V 200Ah Capacity:

    • The battery has a 12V nominal voltage and a 200Ah (amp-hour) capacity, meaning it can supply a 12V system with a continuous current of 200 amps for an hour or 1 amp for 200 hours. This capacity is sufficient for powering various systems such as lighting, appliances, and electronics, typically used in recreational vehicles (RVs), boats, and solar setups.
  2. 2560Wh Energy Storage:

    • The 2560Wh (watt-hours) represents the total energy the battery can store and deliver. This means the battery can provide 2560 watts of power for one hour or 1 watt for 2560 hours, depending on the load. This energy storage is enough for daily use in medium to large RVs, boats, or solar setups.
  3. LiFePO4 (Lithium Iron Phosphate) Chemistry:

    • LiFePO4 is one of the safest and most durable lithium battery chemistry types. It is known for its long cycle life, thermal stability, and inherent safety. LiFePO4 batteries have a much longer lifespan than traditional lead-acid batteries (often 2,000+ charge cycles compared to lead-acid's 500-800 cycles).
    • LiFePO4 batteries are also lighter and more compact compared to their lead-acid counterparts.
  4. Heated Battery Design:

    • This particular model comes with a built-in heating element that ensures the battery operates efficiently in cold temperatures. Lithium batteries, especially LiFePO4 batteries, can lose capacity and performance in freezing conditions (below 32°F or 0°C), so the integrated heating system helps maintain optimal performance by keeping the battery at a suitable temperature.
    • This feature is especially useful for RV owners, campers, or boaters who need a reliable power source even in winter conditions.
  5. Built-in Battery Management System (BMS):

    • The battery is equipped with a BMS that ensures safe operation by protecting against overcharging, over-discharging, short circuits, and thermal overloads. This enhances both the safety and longevity of the battery.
  6. Wide Applications:

    • Solar Power Systems: The 12V 200Ah battery is ideal for off-grid solar applications, providing efficient energy storage for homes, cabins, or remote locations.
    • Recreational Vehicles (RVs): Provides power for RV systems, including lighting, entertainment, and appliances, especially useful for long trips or off-grid camping.
    • Boats and Marine Applications: These can be used in boats for powering electronics, lights, and small appliances, providing long-lasting, reliable power even in harsh marine environments.
    • Backup Power: Ideal for backup power solutions for homes or small businesses.

The WEIZE 12V 200Ah 2560Wh Heated LiFePO4 Lithium Battery is an excellent choice for anyone looking for a durable, efficient, and reliable power source in environments where cold temperatures can impact performance. Whether for RVs, solar power systems, or marine use, this battery offers the capacity, safety, and longevity needed for off-grid living and outdoor activities.

Harley-Davidson battery

My original Harley battery was struggling to turn the high compression bike over with only 340 cold cranking amps, I put this lightweight 600 cold cranking amps battery in and wow could not believe how quickly it spun the bike over. Very happy. Just ordered another one for one of my other bikes.
