Benefits of Lifepo4 Battery Pack
1. Security. The P-O bond in lithium iron phosphate crystal is stable and difficult to decompose. Even at high temperatures or overcharges, it will not collapse and heat or form strong oxidizing substances like lithium cobalt, so it has good safety.
2. High cycle times and good service life. The cycle life of long-life lead-acid battery is about 300 times, and the maximum is 500 times. The cycle life of lithium iron phosphate power battery is more than 2000 times, and the standard charging (5-hour rate) can reach 2000 times. The lead-acid battery of the same quality is "new half a year, old half a year, and maintenance half a year", which can last for 1 to 1.5 years at most, while the lithium iron phosphate battery will have a theoretical life of 7 to 8 years under the same conditions.
3. Good high-temperature performance. The electrothermal peak value of lithium iron phosphate can reach 350 ℃ - 500 ℃, while that of lithium manganate and lithium cobaltate is only about 200 ℃. The operating temperature range is wide (- 20C –+75C), and the electric peak value of lithium iron phosphate with high-temperature resistance can reach 350 ℃ - 500 ℃, while that of lithium manganate and lithium cobaltate is only about 200 ℃.
4. High capacity. It has larger capacity than ordinary batteries (lead acid, etc.). The monomer capacity is 5AH-1000AH.
5. No memory effect. Rechargeable batteries often work under the condition of being fully charged, and the capacity will rapidly fall below the rated capacity. This phenomenon is called memory effect. For example, NiMH and NiCd batteries have memory, but lithium iron phosphate batteries have no such phenomenon. No matter what state the battery is in, it can be used as soon as it is charged, without having to be discharged before charging.
6. Lightweight. The volume of lithium iron phosphate battery with the same specification and capacity is 2/3 of that of lead-acid battery, and the weight is 1/3 of that of lead-acid battery.
7. Environmental protection. The battery is generally considered to be free of any heavy metals and rare metals (NiMH battery requires rare metals), non-toxic (SGS certification passed), non-polluting, compliant with European RoHS regulations, and an absolute green environmental protection battery certificate.
