Product Features:
- Strong Compatibility: Standard 19-inch 2U rack-mount design for easy replacement and capacity expansion.
- High Safety: BMS with multiple protection features, including overcharge, over-discharge, over-temperature, over-current, and short-circuit protection, ensuring safe and reliable performance.
- Long Float Charge: Designed for extended float charging, allowing the battery pack to remain in float charge mode for prolonged periods.
- Flexible Configuration: Uses standard 26650 cells, with the option to replace with different discharge rates and capacities to meet various application requirements.
- Lightweight: Weighs about one-third of an equivalent lead-acid battery.
- Long Service Life: Lasts 4–5 times longer than lead-acid batteries, with no memory effect and a calendar life exceeding 10 years.
- Capacity Expansion: Supports multiple battery packs connected in series or parallel for UPS capacity scaling.
- Flexible Backup Time: A single module can provide over 30 minutes of backup power, with parallel connections extending runtime as needed.
