Why choose lifepo4 battery instead of lead acid 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
Solar power system.
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
How to choose a suitable battery?
1. Currrent: the discharge current of battery required is very important information for designer. For battery solar, the max current information of inverter is needed to confirm. And the solar charge controller information is also need to be informed, how many max current of solar charger controller pass .
2. Size: for different usage, the needed size of battery is different. we can do custom design.
3. holder: we provide epoxy panel+pvc film holder, Steel case holder, SLA case holder and Aluminum case holder.
When the above information is confirmed by you.It is easier to provide the most suitable battery.
