Are lithium batteries safe?

LiFePO4 (Lithium Iron Phosphate) batteries like Pylontech are very safe. They do not burn or explode even if damaged, unlike regular lithium-ion batteries. This is why we exclusively choose LiFePO4 technology.

How long does a lithium battery last compared to lead-acid?

Lithium batteries last 10-15 years with daily use, while lead-acid batteries need replacement every 2-4 years. This means you may need 3-5 lead-acid batteries to equal the lifespan of one lithium battery.

Why are lithium batteries more expensive?

Initial price is higher due to advanced manufacturing technology and built-in Battery Management System (BMS). But when calculating cost per charge cycle, lithium is much cheaper in the long run.

Can I use a lithium battery with any inverter?

Not always. Lithium batteries need an inverter compatible with the communication protocol (like CAN or RS485). OPTI-Solar and Huawei inverters we provide are fully compatible with Pylontech batteries.

What is Depth of Discharge (DoD) and why is it important?

DoD is the percentage of capacity you can use. Lithium batteries allow 80-95% use, while lead-acid only 50%. This means a 5kWh lithium battery provides more usable energy than a 5kWh lead-acid battery.

Are lithium batteries affected by high heat in Yemen?

LiFePO4 technology is designed to work in high temperatures (up to 50°C). Pylontech batteries are tested in environments similar to Yemen and work efficiently. Lead-acid batteries degrade faster in heat.

When should I choose lead-acid instead of lithium?

Only in two cases: (1) Very limited budget and cannot wait to save, (2) Rarely used emergency system. In all other cases, lithium is the better choice economically and practically.

Educational Comparison

Lithium vs Lead-Acid Batteries

Comprehensive guide to understanding battery technology differences. Make your decision based on actual needs, not just price.

Quick Summary

Lithium lasts 5x longer than lead-acid (cheaper long-term)
You can use 95% of lithium capacity vs only 50% for lead-acid
Lithium is 3x lighter and safer (no toxic gases)
Lead-acid only for very limited budgets or rare use

Detailed Comparison Table

Criteria	Lithium (LiFePO4)	Lead-Acid
Lifespan	6,000+ cycles (10-15 years)	300-500 cycles (2-4 years)
Depth of Discharge (DoD)	80-95% safe	50% only to preserve lifespan
Efficiency	95-98%	80-85%
Weight	Light (1/3 the weight)	Very heavy
Heat Tolerance	Good (up to 50°C)	Poor (degrades quickly)
Maintenance	Maintenance-free	Needs periodic water checks
Initial Price	Higher (2-3x)	Cheaper
Safety	Very safe (LiFePO4)	Produces toxic gases

Result: Lithium wins in 7 out of 8 criteria. Lead-acid wins only in initial price.

Total Cost Analysis

5kWh Lithium Battery

Usable capacity (95% DoD)4.75 kWh

Cycle count6,000+

Total available energy28,500 kWh

Expected lifespan10-15 years

5kWh Lead-Acid Battery

Usable capacity (50% DoD)2.5 kWh

Cycle count400

Total available energy1,000 kWh

Expected lifespan2-4 years

Conclusion: Lithium provides 28x more energy

Even if lithium costs twice as much as lead-acid, it provides 28 times the energy over its lifetime. This makes the cost per kWh much lower with lithium.

Which Battery Suits Your Use?

Residential home (daily use)

Why is Lithium Best for Yemen?

High Heat

Lead-acid batteries lose 50% of their life in high heat. Lithium is designed to work up to 50°C.

Frequent Outages

Intensive daily use quickly consumes lead-acid cycles. Lithium handles thousands of cycles.

Lack of Maintenance

Lead-acid needs periodic maintenance that may not be available. Lithium is maintenance-free.

Import Difficulty

Replacing batteries every 2-3 years is costly and complex. Lithium lasts 10-15 years.
