Tested Cells


    Analyzed Cells and Battery Packs

    Higherwire not only builds our own battery energy storage systems (BESS), we also analyze and assemble packs for second life applications such as stationary energy, RVs, backup and renewables. Each of these loose cells and packs have been fully analyzed using our patent-pending process to ensure safety and reliability.

    Shipping and Returns

    We ship the majority of our orders by the next business day. Lithium batteries may take up to two business days to process to accommodate inspection and logging into our system.

    Our shipping rates are based on the weight of all ordered products plus estimated weight of packaging. We make every effort to forecast an accurate shipping cost, but cannot be 100% certain in all cases. Please contact us at sales@higherwire.com with any questions prior to purchase.

    We have a 30-day return policy, which means you have 30 days after receiving your item to request a return.

    To be eligible for a return, your item must be in the same condition that you received it, unused, and in its original packaging. You’ll also need the receipt or proof of purchase.

    About Us

    Our mission is to reduce barriers to renewable energy storage and generation. We're closing the loop on the lithium battery supply chain by creating innovative solutions such as our patent-pending process to reintegrate batteries into Second Life applications. These lithium-ion battery assemblies help us achieve that goal by providing our customers with low-cost energy storage options.
