Quality features of OPTIMUM LiFePO4 Battery Pack
in optimum,each cell and pack is produced with the principle "conformity in 6 aspeacts and 3 inspections in 3 stages",the high stability and reliability can be guaranteed.
"Conformtity in 6 aspects" is a principle developed by OPTIMUM engineers in production and inspection process.The application of it ensures conformity of packs and improves service term of pack obviously.
confirmtity in 6 aspects principle
1.conformity in capacity
2.conformity in impedance
3.conformity in self-discharging
4.confirmity in soc
5.confirmity in discharge stage
6.confirmity in Charge CC ratio
3 inspections in 3 stages

Electrochemistry performance

No.	Project	Standard	Testing method
1	Discharge performance in normal temperature	Discharge capacity /standard capacity×100% (A)0.2C5A ≥100% (B)1C5A ≥95% Charge-discharge curve should be smooth	Charge with 0.2C5A standard charge in the condition of temperature 25°C±5°C,relative humidity 45%~80%(if there is no especial statement,the charging way is same as this), rest for 10min,separated discharge with 0.2C5A,1C5A to cut-off voltage 40.0V,cycles for three times,One cycle capacity arrive standard, that's to say it is qualified.(The below as the same);
2	Charging keep ability in normal temperature	Remain capacity≥standard capacity *95%	After standard charged,rest for 28 days,discharge with 0.2C5A to 40.0V,test the Remain capacity.
3	Cycle life	Capacity≥ Standard capacity *80%	After 0.2C standard charged ,discharge with 0.2C5A to 40.0V.rest for10min,cycles for 2000 times.
4	Storage performance	Capacity can be kept ≥80% Storage for 12 months.	After standard charged,rest it in 25°C±5°C for 12 months. Then discharge with 0.2C5A to 40.0V, testing the battery capacity. 0.2C/0.2C test the recover capacity, cycle for 3 times ,One cycle capacity arrive standard, that's to say it is qualified.
