Core Advantages
Stackable Modular Design
Standard 19-inch rack-mounted design allows vertical stacking and parallel expansion. Supports up to 63 parallel modules to meet various scale energy storage needs while saving installation space and reducing deployment costs. Ideal for space-constrained environments like data centers and equipment rooms.
High Safety & Stability
Utilizes LiFePO4 battery cells with cobalt-free formula, offering excellent thermal stability and no risk of thermal runaway. Built-in aerosol fire extinguisher and multi-layer protection mechanisms including overcharge, over-discharge, over-current, short-circuit, and over-temperature protection ensure safe and stable operation in harsh environments.
Application Scenarios
Emergency power supply for hospitals, shopping malls, factories, and other facilities. Provides reliable power support during grid failures to ensure continuous operation of critical equipment.
Frequently Asked Questions
How many modules can this 48V 200Ah rack-mounted battery be paralleled with?
Up to 63 modules can be paralleled, allowing flexible expansion of energy storage capacity according to actual needs. Suitable for energy storage projects of different scales from residential to small commercial applications.
What is the difference between this battery and traditional lead-acid batteries?
Compared with traditional lead-acid batteries, it offers significant advantages: longer cycle life (6000+ cycles vs. 1000-2000 cycles), lighter weight, smaller volume, no regular watering maintenance required, lower self-discharge rate, higher efficiency, and better safety. This results in space savings and reduced long-term operating costs.
What is the charging and discharging temperature range of the battery? Can it be used outdoors?
Charging temperature range is 0~55℃, and discharging temperature range is -20~55℃, allowing adaptation to most outdoor and indoor environments. The IP22 protection level effectively prevents dust and dripping water, making it suitable for outdoor telecommunication base stations and photovoltaic power stations.
Does the battery need regular maintenance? What are the maintenance points?
The battery features maintenance-free design, eliminating the need for regular watering or complicated maintenance. Daily maintenance only requires checking battery installation tightness, keeping surfaces clean and dry, avoiding exposure to high temperature, high humidity, and corrosive environments, and regularly monitoring system status through the monitoring system.
What is the warranty policy for this battery?
We provide a 10-year warranty service. During the warranty period, if the battery experiences quality problems (non-human damage), we provide free repair or replacement services. The warranty period is calculated from the delivery date, with specific terms subject to the official warranty agreement.
Can the battery be stacked arbitrarily? Is there a limit to the number of stacked layers?
The battery is designed for stackable installation, but we recommend stacking no more than 4 layers. Excessive stacking increases pressure on bottom batteries, which may affect service life and safety. We recommend following the official installation guide to ensure stable operation.
