1. Volume: the volume of lead-acid batteries is relatively large, generally 15-30kg, while lithium iron phosphate batteries are relatively small, usually 2.5-3.0kg.
2. Energy density ratio: the energy density ratio of lithium iron phosphate batteries is 3-4 times, 2.5 times higher than nickel-cadmium batteries, and 1.8 times higher than nickel-cadmium batteries.
3. Service life: lead-acid battery up to 300 cycles, can be charged and discharged at room temperature 1 degree Celsius, can be after 2000 cycles, the capacity of the battery is still greater than 80%, the life of the 3C battery can reach 800 times, lead-acid battery has high requirements for environmental temperature, in an extreme environment, its service life will not exceed 5 years, under the same working conditions, the service life of lithium iron phosphate is also longer.
4. Safety: under the fierce impact, the lead-acid battery will explode, endangering the user’s life; lithium iron phosphate batteries fully meet the safety requirements for lithium cobalt oxide batteries and lithium manganate, and will not explode even in a fierce impact.
5. Temperature: the working environment of lead-acid battery is -20℃-50℃, with low self-timer ability. The maximum thermal energy of lithium iron phosphate battery packs reaches 350-500℃, and 100% of the heat can still be released under higher temperature conditions.
6. Charging efficiency: lead-acid battery, normal charging state, charging time 8-10 hours, because of its own material and electrolyte is better, so it can be quickly charged, can be quickly charged and discharged under 2C high current, using a special charger 1.5C charging for 40 minutes.
7. No memory effect: lead-acid batteries have a memory effect, the working state of the rechargeable battery is often full, not fully released, the capacity will soon decrease. Lithium iron phosphate batteries do not have this situation, no matter what the situation, they can be used at any time.
8. Green environmental protection: lead-acid batteries have high lead content, which will cause environmental pollution if not properly disposed of. Lithium iron phosphate is a non-toxic substance and is a green and environmentally friendly battery.
9. Use and maintenance: since there are certain problems in the use and maintenance of lead-acid batteries, frequent maintenance is required, and maintenance costs will increase accordingly. The lithium iron phosphate battery, because of its good stability, does not require frequent maintenance.
