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
Battery assembly, paralleled modules, finished packs

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
Most economic
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
