48-Volt Lithium-Ion Battery with 21700 Cells, 185Ah (8.87 kWh) (Used/Tested)

This server rack battery was used for testing, and have very few cycles on it. We counted 546 cells total (26 rows of 22), each cell with 4.2Ah (15.12Wh) capacity. They appear to be SVOLT N21700CM cells. Both positive and negative ends have 4 spade connectors with 12 awg wire, meaning this pack can easily deliver 100+ amps of continuous power. This is a 48-volt nominal battery, with 13 series strings of 44 cells in parallel (13s44p). That's 184.8 Ah, or 8.87 kWh. Wow! This does not have a BMS or outer enclosure, but the cell-level nickel strip is covered with insulation. All cells are at approximately 4.0 volts. This is the perfect inexpensive pack for a 48-volt system, simply add your BMS of choice and you have
