Get QuotesAt Aquion, we are changing the energy storage paradigm by manufacturing high-performance batteries that are clean, safe, and sustainable.
Aquion Energy manufactures batteries that are safe, reliable, sustainable, and cost-effective. Our Aspen batteries are based on our proprietary Aqueous Hybrid Ion (AHI™) chemistry which has a unique environmentally-friendly electrochemical design, and they are the first and only batteries in the world to be Cradle to Cradle Certified™. Aspen batteries contain no heavy metals or toxic chemicals and are non-flammable and non-explosive, making them the safest batteries in the world – designed for use in pristine environments, island locations, homes and businesses.
High internal impedance - turn on the kettle 2kW the volts at the battery terminals drop significantly, so by the time the inverter compensates, you get a brown out. Sealed lead acid can deliver more power with lower internal impedance. I worked with the support staff fir twelve months to resolve, never could, it was the batteries.
Due to the internal impedance you cannot put lots of charge into the batteries. There was one technical update provided to increase the charge volts to compensate. This will boil the batteries.
Battery lasted under two years. company filed for bankruptcy when all the first round of claims would have come through.
I think these batteries would be okay for an application with a slow drain and a slow charge, not suitable for a domestic off grid system running kettles, toasters, air cons. Also the round trip efficiencies are lower than the specs sheet.
I had a 24 kWh battery and used about 7kWh overnight
