The Discover Energy AES RACKMOUNT Heated Lithium Battery is a high-performance energy storage solution designed for residential solar, off-grid power, and compatible backup energy systems.
Featuring advanced lithium iron phosphate technology, integrated battery heating, and intelligent battery management, this battery provides dependable rechargeable energy storage in a compact rackmount format.
Unlike the standard AES RACKMOUNT battery, the heated model incorporates an internal heating system that helps support charging during colder conditions.
Its modular architecture, high-current performance, and communication capabilities make it a practical choice for homeowners and solar professionals building or expanding compatible battery storage systems.
The Discover AES RACKMOUNT Heated Battery features an integrated heating system designed to address a common limitation of lithium batteries: restricted charging at low temperatures.
When battery temperatures fall below the appropriate charging range, the heating system helps warm the cells to support safe charging conditions.
This feature is particularly valuable for protected battery installation areas that experience seasonal temperature fluctuations.
Important: Integrated heating does not make the battery suitable for direct outdoor exposure. Installation must meet the manufacturer's environmental and enclosure requirements.
Discover's AES RACKMOUNT battery uses lithium iron phosphate chemistry, widely used in stationary energy storage systems for its thermal stability, durability, and rechargeable performance.
Unlike traditional lead-acid batteries, LiFePO₄ batteries do not require routine watering or electrolyte maintenance.
The Discover AES RACKMOUNT battery includes an intelligent battery management system designed to monitor operating conditions and protect the battery during charging and discharging.
The BMS manages battery safety functions and supports communication with compatible energy storage equipment.
The AES RACKMOUNT battery is designed for installation in compatible battery racks and enclosures, making it well suited for organized residential and commercial energy storage equipment layouts.
Its compact modular format allows installers to plan storage systems around available space, service access, and future capacity requirements.
Battery racks, cabinets, and interconnection accessories are selected separately unless specifically included by the seller.
The Discover AES RACKMOUNT platform supports modular energy storage expansion using compatible battery modules and approved electrical connection methods.
Additional battery capacity can help support longer energy storage durations or increased energy demands when the inverter and overall system are designed for the expanded configuration.
All battery expansion must follow Discover's installation requirements for battery matching, electrical protection, communication, and cable sizing.
Discover AES RACKMOUNT batteries feature a LYNK communication interface designed for use with compatible external communication equipment.
The optional Discover LYNK II Gateway supports communication between approved Discover batteries and supported inverter-chargers.
With an approved integration, battery operating information can help the inverter manage charging and discharging according to the battery's requirements.
Compatibility note: The LYNK II Gateway is sold separately. Confirm the exact inverter model, firmware, gateway, and communication requirements before installation.
