Advantages of 6V Lithium-ion
Efficiency
Lithium-ion batteries charge faster and retain energy longer, making them more efficient for daily use.
Cost Savings
While upfront costs may be higher, modern batteries save money over time due to their durability and low maintenance requirements.
Enhanced Safety
Newer battery technologies have built-in safety features to prevent overheating, short-circuiting, and other risks.
Adaptability
Alternatives to lead-acid batteries are better suited for integration with renewable energy systems, such as solar and wind power.
Lithium-ion Phosphate VS Lead Acid
| Comparison Details | Lead-acid Battery | Lithium-on Phosphate Battery | Remarks |
| Environmental protection | Contaminated by heavy metal lead | No pollution (Not absolute) | Lithium-ion phosphate is more environmentally friendly |
| Volume capacity density | Volume energy density 100% | Volume energy density 150% | Lithium-ion phosphate is 30% smaller in size |
| Mass capacity density | 50-70wh/g | 200-260wh/g | Lithium-ionn phosphate has 3~5 times higher energy |
| Cycle life | About 500 cycles, obvious memory effect | 2000 cycles, no memory effect | Lithium-ion phosphate has a longer life |
| Self-discharge rate | Lead-acid battery 15-30% | Monthly self-discharge of lithium-ion battery <3%,More than 90% left after one month | Lithium-ion phosphate has low self-consumption |
| Discharge characteristics | 70% power left after one month | Only about 60% of the power can be discharged | Lithium-ion phosphate has higher discharge utilization |
| Voltage platform | Lead-acid battery is 2V | Lithium iron phosphate battery voltage platform 3.2V | Lithium-ion phosphate has high voltage and sufficient power |
