We've removed these Samsung 94Ah cells from residential energy storage packs by milling off the laser-welded bus bars, then drilling and tapping the electrode to install 1/4"-20 studs. We use an industrial mill for each operation, which ensures repeatability and safety of the cells. Even the tapping operation is done on the mill.
These cells are great for many different applications ranging from stationary storage to EVs. In fact, they're used in the BMW i3, Fiat 500e, VW e-Golf and other EVs, and we've used them in applications ranging from solar backup to golf carts.
We tested the first few batteries we produced, charging at 30 amps and discharging at 50 amps. They tested at 99Ah with no hot spots or fireworks, and impedance was right at 0.50mΩ. All cells are checked and charged to ~3.6v for shipping per IASA and DOT regulations.
Li-Ion prismatic Samsung 94 Ah special cell for EV and energy storage applications provides long cycle life > 3.200 cycles by Nickel-cobalt-manganese (NCM) technology.
Nominal voltage of the cell is 3.7 V and the operational voltage is 2.75 V – 4.15 V.

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 email@example.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.
