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
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 |
