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

Storage and Transportation:


   1. Based on the character of cell, proper environment for transportation of LiFePO4 battery pack need to be created to protect the battery. 


   2. During transportation, 50% SOC must be kept to ensure that short circuit, appearance of liquid in the battery or immersion of battery in liquid never occur.


3. Battery should be kept at -20°C~45°C in warehouse where it’s dry, clean and well-ventilated.


4. During loading of battery, attention must be paid against dropping, turning over and serious stacking.
