AES RACKMOUNT Battery Module

AES RACKMOUNT Battery Modules are manufactured with the highest-grade cobalt-free LiFePO4 cells for safety, reliability and long life. The high-current GEN-4 BMS delivers superior peak power for demanding load support and lightning-fast 1C charge and discharge rates.

Networking AES RACKMOUNT Battery Modules with the LYNK II Gateway enables plug-and-play closed-loop communication with industry-leading hybrid inverters and dramatically elevates charging performance.

AES RACKMOUNT Battery Modules are available with a BMS-managed heat mat for operation in cold climates.
