Much Longer Life Span

• Lithium (LiFePO₄): 3000–6000 cycles

• Lead-acid: 300–500 cycles

Lithium lasts 6–10× longer.
A lead-acid battery used daily may die in 1.5–2 years

while lithium lasts 8–12 years.

Better Depth of Discharge (DoD)

• Lithium: 80–100% usable capacity

• Lead-acid: Only 30–50% usable

For Example:
A 150Ah lead-acid gives only 60–75Ah usable,
but a 100Ah lithium gives 90–100Ah usable.

So lithium gives more real power in a smaller size.

Fast Charging

• Lithium: charges 3–4× faster

• Lead-acid: slow, needs stage charging

Lithium allows fast energy recovery (perfect for solar).

High Efficiency

• Lithium efficiency: 95–98%

• Lead-acid efficiency: 70–80%

You lose far less power as heat in lithium.

Lightweight & Compact

Lithium is 50–70% lighter

Easy to install, wall-mount, or use in portable systems

Low Maintainence

Lead-acid requires:

• water top-up

• venting

• equalization charging

• careful handling

Lithium requires:

• zero maintenance

A built-in BMS (Battery Management System) protects from:

• overcharge

• over-discharge

• short circuit

• temperature issues

Total cost is cheaper over time

While lithium costs more upfront, the per-year cost is much lower because:

• longer life

• no maintenance

• more usable capacity
