We have two 24v battery modules that were built a couple years ago for development testing. They've gone through approximately 150 cycles at very low discharge rate, well under 10a. They are in a 7s20p configuration and consist of the following cells:

  • NCR18650B, qty 14
  • NCR18650A, qty 21
  • NCR18650GA, qty 105

Both of these tested at above 50Ah, or nearly 1.5 kWh. Each module will come with a BMS pre-wired, meaning you can simply connect positive and negative leads for a 24v battery!

Our Process

These are used cells. Higher Wire safely removes them from consumer electronics battery packs and analyzes them using the same process and equipment as many lithium-ion battery OEMs. That includes a full charge at a rate at or below the manufacturer's specification, internal resistance using both DC and AC analyzers, and full monitored discharge testing to determine capacity. They are then graded according to these and other key characteristics as compared to OEM data sheets.


We may wrap cells in new heat shrink if the original wrapping was significantly damaged. We inspect every cell for corrosion, pitting or damage and recycle any that are suspect. Cells may be delivered with adhesive or tape still attached, or damaged heat shrink. Check out or selection of pre-cut heat shrink, adhesive insulator rings and other accessories to help you finish your build.

Lithium Battery Safety

  • Misusing or mishandling a lithium-ion battery may cause fire or explosion, which can result in personal INJURY or DEATH and property damage. You MUST read the safety warnings and resources before purchasing, using, and/or handling batteries. Even if properly handled, lithium-ion batteries may still catch fire or explode. The buyer acknowledges these risks and absolves Higher Wire Inc. of any responsibility for any damage these cells may cause.
  • Unless otherwise stated, batteries sold by Higher Wire are unprotected and not recommended by us or their original manufacturers for use unless equipped with a protection circuit board (PCB), battery management system (BMS), and/or similar device.
  • Lithium batteries must be properly disposed of – NOT in a fire or in the trash. Laws vary at the city, state and national level, and it is the buyer’s responsibility to ensure they are recycling lithium batteries properly. Many local governments and retail stores offer free recycling, and you should review our How to Recycle Lithium Batteries page.
  • Unless otherwise stated, batteries sold by Higher Wire are used and have no warranty, either from Higher Wire or the original manufacturer. Although we visually inspect and analyze/grade all batteries prior to sale, it is the buyer’s responsibility to inspect all batteries for physical damage, corrosion, and voltage upon receipt. Contact sales@higherwire.com immediately if there are any issues with an order, and do not use any battery that is damaged or below 3.0 volts upon receipt.
  • Unless otherwise stated, batteries sold by Higher Wire are charged to 40% SOC (~3.4v) per IATA and DOT regulations. Charge battery fully to 4.2V before first use.
  • Never attempt to mix and match brands, including models as well as old and new, used, and unused lithium-ion batteries. It is the buyer’s responsibility to ensure a battery is compatible with the intended application. Contact sales@higherwire.com with any questions, including technical.
  • Unless otherwise stated, batteries sold by Higherwire are shipped as UN3480 per DOT and IATA regulations. We ship using ground shipping to minimize risk of damage to persons or property.
  • Go to our Lithium Battery Safety page for full 18650 lithium battery safety precautions.

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@higherwireenergy.com with any questions prior to purchase.

We pack and label all lithium battery shipments in accordance with Federal Regulation 49CFR173.185, as well as USPS Publication 52 Hazard Class 9 or UPS/Fedex guidelines. Unless otherwise stated, lithium batteries are not eligible for free shipping.

We try to pack all items in an order in a single box, however we may on occasion need to ship items separately. Special shipping does not apply to lithium ion batteries, and orders that include batteries may not qualify for free or expedited shipping.
