FAQs for ,

What is the nominal capacity and stored energy of the Vxl5100 battery pack?
The Vxl5100 battery pack features a nominal capacity of 100Ah and operates at a nominal voltage of 51.2V, which means it stores approximately 5.12 kWh of energy. This combination provides a robust energy reserve suitable for a wide range of applications, delivering reliable and consistent power output for your energy storage needs.
Yes, Vxl5100 battery packs can be connected in parallel to increase total capacity and stored energy. You can combine up to 16 Vxl5100 packs in parallel, allowing you to build medium to large-scale energy storage systems tailored to your specific power and runtime needs. This modular design offers great flexibility, letting you scale your battery bank as your energy requirements grow, while maintaining safe, balanced, and efficient operation through the integrated Battery Management Systems (BMS) in each pack.
The Vxl5100 battery pack can deliver a peak power output of approximately 5.12 kW. This is based on its maximum continuous current of 100A at a nominal voltage of 51.2V (Power = Voltage × Current). This high instantaneous power allows the pack to handle demanding loads and provides strong, reliable performance for a wide range of applications, including energy storage and backup power systems.
The Vxl5100 battery pack is designed for long-term reliability, sustaining more than 6000 charge-discharge cycles when operated at an 80% Depth of Discharge (DoD) and a 0.2C discharge rate. This means you can expect many years of dependable service even with frequent cycling, making it an excellent choice for demanding energy storage applications that require consistent performance over time.
The Vxl5100 battery pack has compact dimensions of 430 × 442 × 136 mm (L × W × H) and weighs approximately 48 kg (about 106 lbs). This size and weight make it well-suited for installations where space is limited but robust energy capacity is needed. Its relatively slim profile allows for flexible placement in racks or cabinets, while the weight remains manageable for standard handling and setup procedures.
To keep your Vxl5100 battery pack performing at its best and lasting as long as possible, follow these maintenance tips: Maintain Proper Temperature: Operate and store the battery within the recommended temperature range (ideally 0°C to 35°C) to prevent stress on the cells. Avoid Over-Discharge and Overcharge: Use a compatible charger and monitor battery levels to prevent deep discharges or excessive charging, which can shorten battery life. Ensure Good Ventilation: Install the battery in a well-ventilated area to help dissipate heat during operation and charging. Regularly Check BMS Data: Use the battery’s built-in Battery Management System to monitor voltage, current, temperature, and overall health, ensuring early detection of any issues. Keep Terminals Clean: Periodically inspect and clean battery terminals to maintain good electrical connections. Store Properly: If storing for extended periods, keep the battery partially charged (around 50–70%) and check charge levels every few months. Following these simple steps will help you maximize reliability, safety, and service life of your Vxl5100 battery pack.
The Vxl5100 battery pack is versatile and well-suited for a variety of applications. It’s ideal for residential energy storage, helping homeowners store solar power for use during evenings or outages.
