GREPOW Li+ UPower series use soft pack stacked LiFePO4 batteries, which are a replacement for traditional lead-acid UPS batteries.
Due to the special stacking process, it can realize ultra-high rate charging and discharging performance, and the volume and weight can be reduced by about 50% under the same discharging current requirement, and it can even be discharged continuously with high current in -20℃ low temperature environment, with energy density ratio as high as 150Wh/kg, and the cycle life as high as 4,000 cycles, and maintenance-free cost, which can save a large amount of manpower cost for the enterprise and significantly reduce the total operating cost.
