New Samsung 87v 224ah 19.5kWh Rack Mount - $46/kWh

Amazing deal at this price for unused batteries. Of course this will have to ship freight but we include lift gate and residential delivery service. Also orders $2000 or above will ship for free.

The batteries are still in the original crates and are overstock from a larger project. All cells are perfectly balanced and resting at nominal voltage.

These are in 24s2p configuration using 3.63v 120ah cells. The lid pops off for easy access to the busbars. Busbars are laser welded. You also have access to the balance lead wiring harnesses so you can easily wire your own BMS to these. Splitting these into difference voltage would require careful busbar cutting with a dremel wheel. very doable but of course at your own risk.

Dimensions are 51" x 14.5" x 8"

Cells are Samsung SDI 120ah prismatic lithium ion. Voltage range is 2.8-4.2v per cell.

Note: the voltage range printed on the module shows the rating from 3.1-4.1v per cell since that is what the original application required. If you use the full range of the cells you'll be able to get 240ah instead of 224ah since the cells are 120ah in 2p configuration. So you'll get above 21kWh out of these modules that way. Of course, the 3.1-4.1v per cell range is a nice sweet spot for nearly doubling cycle life with minimal capacity loss.
