Advantages against Lead Acid battery:
- Weight: Less than half the weight of lead acid battery.
- Discharge: Lithium-ion batteries are discharged 100% versus less than 80% for lead acid. Most lead acid batteries do not recommend more than 50% depth of discharge.
- Cycle Life: Rechargeable lithium-ion batteries cycle 2000-5000 times or more compared to just 400-500 cycles in lead acid batteries.
- Voltage: Lithium-ion batteries maintain their voltage throughout the entire discharge cycle. This allows for greater and longer-lasting efficiency of electrical components. Lead acid voltage drops consistently throughout the discharge cycle.
- Cost: Despite the higher upfront cost of lithium-ion batteries, the true cost of ownership is far less than lead acid when considering life span and performance.
- Environmental Impact: There are far less disposal and environmental hazard posed by lithium batteries compared to the short-lived and toxic lead acid batteries.
- LiFePO4 battery is the most stable and safest among other lithium ion batteries.
