Performance is a cornerstone of the BAT-LV-W Series, with tailored charge/discharge parameters that balance power and longevity. The BAT-5K-LV-W features a recommended charge/discharge current of 50A, a peak discharge current of 200A (1-second duration), and a maximum continuous charge/discharge current of 100A—enough to power essential home appliances like refrigerators, lighting, and small HVAC systems during grid outages. The BAT-10K-LV-W elevates this performance with a 100A recommended charge/discharge current, 400A peak discharge (3-second duration), and 200A maximum continuous current, capable of supporting high-wattage devices such as electric stoves, washing machines, and electric vehicle chargers. Both models adhere to precise voltage thresholds (charge cut-off at 56.16V, discharge cut-off at 45.6V) to prevent overcharging or deep discharge, safeguarding battery health and extending service life.
Durability and longevity are hallmarks of the BAT-LV-W Series, with a cycle life of over 6,000 cycles at 80% depth of discharge (DOD)—a benchmark that translates to more than 15 years of reliable use for the average household. This exceptional lifespan is further enhanced by the battery’s robust temperature tolerance: it operates seamlessly in charging temperatures ranging from 0°C to 55°C and discharge temperatures from -20°C to 60°C, making it suitable for climates with extreme temperature fluctuations. Even in storage (at 50% state of charge), the battery maintains stability for up to 3 months in 20°C–45°C environments, and extended storage is supported at ≤25°C (±3°C) with humidity control (≤85% ±20% RH), ensuring minimal capacity degradation over time.
Installation and usability are prioritized in the BAT-LV-W Series’ design. As a wall-mounted solution, it eliminates the need for floor space, making it ideal for apartments, small homes, or any living space where space efficiency is critical. The compact dimensions—442×500×142mm for the BAT-5K-LV-W (net weight 41.88kg) and 442×820×142mm for the BAT-10K-LV-W (net weight 78.85kg)—ensure easy mounting and integration into existing home layouts, while natural air cooling eliminates the need for noisy, high-maintenance fans or liquid cooling systems. The IP21 protection rating shields the battery from dust and dripping water, adding an extra layer of safety for indoor use.
