Aquion Aspen 48M Saltwater Battery - 48V (48M-25.9)
New from Aquion - makers of the world's first nontoxic battery - comes the Aquion Aspen 48M saltwater battery: a modular building block for clean energy storage systems featuring 25.9kWh of energy storage at 48V nominal. It is composed of 12 Aspen 48S-2.2 batteries connected in parallel, configured as a single palletized unit and pre-wired as a plug-and-play battery bank with crate and cover. The Aspen 48M itself can can be connected in series with other 48Ms to create clean energy storage systems of up to 1,000 volts DC.
The Aspen 48M is based on Aquion's proprietary Aqueous Hybrid Ion (AHI™) technology that is clean, safe, and sustainable - in fact, Aquion Aspen batteries are the first and only batteries in the world engineered to meet Cradle to Cradle™ certification standards - a prestigious quality mark recognized across industries as a mark of continuous improvement toward the development of sustainable products.
Not only do AHI cells deliver unprecedented eco-friendliness, they also outperform and outlast traditional battery chemistries, allowing for a true 100% depth of discharge (great for use with solar PV) and an incredible 3,000-cycle life with 70% of its original capacity remaining. These batteries are optimized to deliver robust field performance, maintenance-free operation, world-class safety (they're non-flammable and non-explosive), and excellent abuse tolerance, making them ideal for long-term, unsupervised daily cycling applications like residential and off-grid solar, microgrids, and energy management and grid-scale services.
The Aquion Aspen 48M provides an unmatched combination of performance, safety, and environmental sustainability in a cost-effective, modular, and forklift-ready battery platform.
