Each step have QC engineer following :
1. Choose the right battery cells, for different request and dimension, we could select the right battery cells, cylindrical cells or prismatic cells, mainly LiFePO4 cells. Only newly A grade cells used.
2.Grouping the battery with the same capacity and SOC, ensure battery packs have good performance.
3.select the right thickness nickel for working current ,welding the cells at the right way.
4.BMS assembly, assemble the right BMS to the battery packs.
5.LiFePO4 battery packs put into the lead Acid Case before testing
6.Semi-finished product testing and grading
7.Good product glue seal and QC
◆ Safety, Using the technology of lithium iron phosphate cell, superior safety,Long life thousands of cycles, 100%DOD, under normal conditions.
◆ Built-in automatic protection board for over-charge, over discharge, over current and over temperature.
◆ Maintenance free.
◆ Internal cell balancing.
◆ Lighter weight: About 40% of the weight of a comparable lead acid battery.
◆Standard case product and easy installed.
◆Batteries Could be series connect for higher voltage upto 51.2V system.
