Discover® Advanced Energy System (AES) LiFePO4 Lithium batteries offer bankable performance and the lowest cost of energy storage per kWh. AES LiFePO4 Lithium batteries are manufactured with the highest-grade cells and feature a proprietary high-current BMS that delivers superior peak power and lightning-fast 1C charge and discharge rates.

AES LiFePO4 Lithium batteries are maintenance-free, deliver up to 100% depth of discharge, and up to 98% round-trip efficiency. Plug-and-play installation with the best-known off-grid inverters using the LYNK II Gateway makes closed-loop communication simple and easy and dramatically improves charging performance.

UL 9540 partnerships, UL 1973 certification, a 10-year energy throughput warranty, and the capability to be paralleled to up to 148 kWh per LYNK II Gateway make AES LiFePO4 Lithium batteries ideal for solar and stationary energy storage projects.
