Description

This is the AES 44-48-3000 Advanced Lithium Battery by Discover. A smart way to upgrade your lead-acid battery system to the latest in capacity, cycle life, and performance. This battery block provides 2.9kWh of energy for 48V systems, and can be paralleled to meet your needs. Boasting a 98% round-trip efficiency, and placing no limits on partial state-of-charge cycles, the 10-year warranty might just mean this is the last battery you’ll ever need.

AES LiFePO₄ Lithium batteries are manufactured with the highest-grade LiFePO₄ cells and feature a proprietary high peak surge and transient voltage hardened BMS that delivers superior peak power, lightning fast charge and discharge rates and LYNK Solar Gateway functionality for plug-and-play closed loop integration with the worlds best known off-grid inverters and chargers turning a good system into a great one.
