Quality features of OPTIMUM LiFePO4 battery pack
In optimum, each cell and pack is produced with the principle "conformity in 8 aspeacts and 3 inspections in 3 stages", the high stability and reliability can be guaranteed.
"Conformtity in 8 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.
Confirmity in 8 aspects principle
Conformity in capacity
2...Conformity in impedance
3. Conformity in self-discharging
4. Confirmity in voltage (soc)
5. Confirmity in discharge stage
6. Confirmity in Charge CC ratio
7. Confirmity in cycle life
8. Conformity in batch number
3 inspections in 3 stages

|COMPARISON DATA AMONG VARIOUS LITHIUM BASE BATTERIES|
|Cells||Safety||CYCLE LIFE||POWER WEIGHT DENSITY||LONG TERM COST||Temperature Range|
|LiFePO4||The world's most secure battery, no explosion, no pollution, long life||Excellent Cycle life can be as long as over 2,000 cycle, best among all the listed groups.||Acceptable||Excellent|
|Excellent (can be discharged at -45~ 70 Centigrade)|
|LiCoO2||LiCoO2 is expensive, the actual capacity than its theoretical capacity of only (274mAh g-1) about 50%, lower utilization of cobalt; LiCoO2 cycle life has reached 500||Acceptable Cycle life only up to 300~500 cycle. Not good for high C-rate discharge.||Good||High||Decayed beyond 55 ~ -20 Centigrade|
|LiMn2O4||Have to handle with care, or it might explode or catch fire under collision or over-charged.||Unacceptable Cycle life only up to1 500~800 cycle, depending on the discharge C-rate.||Acceptable||Acceptable||High|
|Li(NiCo)O2||Very unstable, must handle with extremely care, it might explode or catch fire under collision, over-charged, short circuit or when heat build-up.||Acceptable Cycle life can be 300~500 cycle. Not good for high C-rate discharge.||Good||High||Decayed extremely fast over 55~ -20 Centigrade|
