5kWh 100Ah 51.2V Stack Rack Battery – Modular Lithium Energy Storage System
What is a Stack Rack Battery?
A Stack Rack Battery is a modular lithium iron phosphate (LiFePO4) energy storage system, typically structured as 51.2V units (e.g., 100Ah for 5.12kWh). Unlike fixed rack-mounted batteries, these batteries are stackable vertically, offering easy installation without additional brackets or bulky cabinets. Their standardized server-rack dimensions make them ideal for space-constrained environments.
Built with smart BMS technology, they support multi-unit parallel connection, real-time monitoring, and intelligent communication with inverters and energy management systems.
