Aspen Saltwater Batteries

Aquion Energy - the manufacturer of the 1st non-toxic battery, has re-branded their product line to Aquion Aspen Batteries. AND - the stacks are now available in both 24V and 48V versions! The Aspen tree is clean, green, stationary, sturdy, robust, and loves sunshine. How appropriate! Aquion keeps improving upon this unique saltwater technology to bring the best they can to the renewable energy market. Each time they strive for higher capacity and improved useabiltity and serviceability.

Aquion Energy's Aspen Battery line of products are the first cost-effective energy storage solution that is high-performance, safe, sustainable, and non-toxic! Based on Aquion's patented Aqueous Hybrid Ion (AHI™) technology (a unique saltwater electrolyte chemistry), these batteries are unlike anything else on the market, and are designed for stationary, long-duration cycling applications. These batteries deliver extremely long cycle life, deep depth of discharge and excellent abuse tolerance. The only Cradle to Cradle Certified energy storage product on the market ! Certified to be safe for the environment from creation to recylcing.

Read our blog "The Science of Aquion Batteries - Clean, Safe Energy Storage". See what sets Aquions apart from so many other batteries.


  • Off-grid and micro-grid applications - these batteries have excellent cycle life even at high depths of discharge, reducing the need for system oversizing and costly battery replacements.
  • Energy management - allows users to avoid peak demand charges by shifting energy use to off-peak hours. Can also serve as an uninterruptible power supply (UPS) in the event of scheduled or unscheduled outages.
  • Grid services - large scale energy storage systems can make the grid more reliable and more flexible because they decouple energy services from a particular fuel source.

  • Extremely high cycle life at 100% depth of discharge (or 70% retained capacity) - 3000 cycles at 100% DoD; 3750 cycles at 80% DoD; 6000 cycles at 50% DoD. Ie, the battery still has 70% of its original capacity at end of life, after 3,000 cycles at 100% DoD.
  • The deep DoD allows you to use a smaller battery bank while enjoying a longer battery life
  • Extremely high abuse tolerance avoids frequent maintenance, downtime, or replacements
  • Ability to stand at partial state of charge with minimal self-discharge to provide reliable performance on demand
  • Wide operating temperature range with minimal degradation
  • Non-toxic, non-flammable, non-explosive, non-corrosive (classified as standard goods vs. hazardous goods)
  • Environmentally benign materials - no corrosive acids or noxious fumes
  • Better value than lead acid or lithium ion - more useable stored energy, and an overall longer lifespan
  • No regular maintenance or active management required
  • Multiple stacks can be wired together in parallel, unlike lead acid batteries

    *The Aspen 48M is composed of 12 Aspen 48S battery stacks connected in parallel and comes pre-wired as a plug-and-play battery bank, with crate and cover.

    Aquion Saltwater Battery Considerations:

  • These batteries do not like to be charged/discharged quickly. Slow and steady is the name of the game. Suggested max current per stack is 17A. The capacity of the battery decreases the more current the battery is hit with. So if you have a lot of high surge equipment like motors or pumps, you may have to oversize your battery bank, or choose a more apporpriate battery technology.
  • Although the batteries have a wide operating temperature range, these saltwater batteries will freeze at 14°F (-10°C). They will thaw, and will still function but in areas of extreme temperatures, capacity may be affected.

    I want some!


    I have a 1KW solar array You should send these to me to test in my Cloudy WV down in the holler real world test facility Located in Almost Heaven's Charleston. I will be happy to put up a real world Youtube test and review Video in exchange for the batteries.
