Used LEV 40 Li Ion 119 cells for quick sale. Used for my off grid system and selling due to upgrade. Still more than 7KWH capacity left with the system from 4.1V to 3.5V discharge . Comes with original interconnecting copper busbars and original cases. The cells are in 13 series and 9 parallel (and two spare cells as well) arrangement for ready integration with 48V inverter system.
