Why choose us
Lithium-ion Battery VS SLA Battery
LFP BatterySLA BatteryRemark
Weighthigh energy density: 110-120Wh/kg, leads to a smaller size and lighter weightlow energy density: 32-37Wh/kgLFP battery is about 70% size and weight of SLA battery, lower the total weight of application
Cycle life4000 cycles and more400-500 cyclesLFP can be used for almost 10 years; SLA can only last for max. 2 years
Capacity Utilization80 to 100% 50 to 60% Capacity Utilization
Efficiencyallows for the same amp hours both in and outvoltage drops quickly and reduces the batteries' capacity while charging and rapid dischargingLFP battery has almost 100% efficiency while SLA battery has only maximum 75% efficiency
CostUp to 8 times the cycle life compared to equivalent SLAA low upfront cost, but a high cost of ownership in long runLower total cost of ownership
Environmental effectclean technology, safer and more environment friendly contains the heavy metal - leadLFP is environment friendly
