Advantage comparing with Lead Acid Battery?
1. Energy Density
Lithium-Ion: Higher energy density, meaning they store more energy for the same weight and size.
Lead-Acid: Lower energy density, making them bulkier and heavier for the same energy storage capacity.
2. Cycle Life
Lithium-Ion: Much longer cycle life,10+ years designed lifespan, up to 6000 cycles.
3. Efficiency
Lithium-Ion: High round-trip efficiency of 90–95%, meaning less energy is lost during charging and discharging.
Lead-Acid: Lower efficiency, around 70–80%, with more energy lost as heat.
4. Depth of Discharge (DOD)
Lithium-Ion: Can be discharged up to 80–90% of their capacity without significantly reducing lifespan.
Lead-Acid: Typically recommended to discharge only 50% of their capacity to maintain longevity.
