The comparison between LFP and SLA
LFP battery | SLA battery | Remarks | |
Weight | high energy density: 110-120Wh/kg, leads to a smaller size and lighter weight | low energy density: 32-37Wh/kg | LFP battery is about 70% size and weight of SLA battery, lower the total weight of application |
Cycle life | 4000 cycles and more | 400-500 cycles | LFP can be used for almost 10 years; SLA can only last for max. 2 years |
Capacity Utilisation | 80 to 100% | 50 to 60% | Most lead acid batteries do not recommend more than 50% depth of discharge |
Efficiency | allows for the same amp hours both in and out | voltage drops quickly and reduces the batteries' capacity while charging and rapid discharging | LFP battery has almost 100% efficiency while SLA battery has only maximum 75% efficiency |
Voltage | maintain voltage throughout the entire discharge cycle | drops consistently throughout the discharge cycle. | A stable droping voltage allows for greater and longer-lasting efficiency of electrical components |
Cost | Up to 8 times the cycle life compared to equivalent SLA | A low upfront cost, but a high cost of ownership in long run | Lower total cost of ownership |
Environmental effect | clean technology, safer and more environment friendly | contains the heavy metal - lead |
