Advantage of lifepo4 battery
1. Green product
LiFePO4 material is no harm to enviroment and human being.
2. Cycle life
Over 2000 cycle times, 8-10 years life.
3. Very safe
It have the best safety and steady performance, no fire, no exploding under the condition of over-charge.
4. Light weight and smaller dimension
The dimension compares with other battery. About 1/2-2/3 weight of lead acid
5. Great capacity and more powerful, rechargeable battery
We can install many single cells in series and in parallet and it can fully discharge
6. No memory effect
It can be recharged anytime, no reduction of the capacity
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
Battery assembly, paralleled modules, finished packs
Protection Board
The protection board, provides protection against overcharge, and short circuit, through monitoring single string of cells. Also it enables every battery pack to obtain independent balancing function.
