| Comparison Dimension | Lead-Acid Battery | Lithium Iron Phosphate (LiFePO₄) Battery |
| Charging Time | Low charge-discharge rate; standard charging requires8-12 hours. Fast charging is not recommended as it may cause irreversible damage to the battery. | High-rate charge-discharge capability; standard charging takes 2-4 hours. Supports fast charging (with compatible charger), enabling 80% charge in 1-2 hours. |
| Range Performance | Lower energy density at the same capacity, leading to shorter range. Example: 48V20Ah battery paired with 800W motor provides a range of approximately 40-50km. | Energy density is 20%-30% higher than lead-acid batteries, delivering longer range. Example: 48V20Ah battery paired with 800W motor achieves a range of around 50-65km. |
| Service Life | Cycle life: 300-500 cycles; service life:2-3 years under normal use. Life expectancy reduces to 1-2 years with frequent heavy loading or long-term storage in a discharged state. | Cycle life: 2000-3000 cycles; service life: 5-8 years under normal use. Resistant to deep charge and discharge, with slow performance degradation even in heavy-load scenarios. |
| Maintenance Requirements | 1. Regularly check electrolyte level and replenish distilled water when insufficient.2. Avoid long-term storage in a discharged state (recharge monthly if unused for an extended period).3. Prohibit overcharging and over-discharging to prevent plate sulfation and damage.4. Charge in a well-ventilated area; avoid high-temperature exposure and direct sunlight. | 1. Essentially maintenance-free, no need for electrolyte inspection or refilling.2. Avoid charging at extreme temperatures (below -20℃ or above 60℃).3. Store with 50%-70% charge remaining if unused for a long time.4. Use a dedicated LiFePO₄ charger; do not use lead-acid battery chargers interchangeably. |
| Cost Efficiency | Low initial investment, approximately ¥300-500 per kWh. High long-term total cost due to frequent replacement needs. | High initial investment, around ¥800-1200 per kWh (2-3 times that of lead-acid batteries). Lower long-term total cost due to extended service life. |
| Additional Key Features | 1. Heavy weight (48V20Ah model weighs about 30kg), increasing vehicle load.2. Poor overcharge resistance; moderate safety performance.3. Weak low-temperature performance (range decreases by over 40% below -10℃). | 1. Lightweight (48V20Ah model weighs about 10kg), reducing vehicle energy consumption.2. Excellent thermal stability; low risk of fire or explosion; high safety standard.3. Superior low-temperature performance compared to lead-acid batteries (range decreases by 20%-30% below -10℃). |
