Why choose us

Lithium-ion Battery VS SLA Battery

LFP Battery

SLA Battery



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 Utilization

80 to 100% 

50 to 60% 

Capacity Utilization


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


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

LFP is environment friendly 

Safety Test

Water Immersion Test Tumbling Test
Mechnical Tst-Mechnical Shock Salt Spray Test
