These are 24v LiFePO4 26650 Battery Packs. They contain x112 26650  3000mAh cells.  They are 8s14p and they contain SONY Branded cells that tested 95%-100%.   The 8s Modules yields 1121Wh.  These modules can be used as 24v on a variety of equipment and can be setup as 48v for DIY PowerWall Applications.  These Modules come out of an Energy storage application where the BMS has failed but the cells have on the average less than 100 cycles. LiFePO4 is the safest Lithium chemistry as its virtually impossible for them to combust,  Lithium Iron Phosphate is the preferred chemistry on energy storage applications due its long cycle life usually in the 4000-6000 cycles.  The only downside has been their high price, but finally I can offer quality modules at around the $100/Kwh.
