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 working current connection busbar, 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 metal Case before testing
7.Product stacted and ready for packing
8.Wood box Stronger Packing
4000 cycles @80% DoD for effectively lower total of ownership cost
Low maintenance batteries with stable chemistry.
Battery Management System (BMS) is incorporated against abuse.
up to 6 months thanks to its extremely low self discharge (LSD) rate and no risk of sulphation.
Save time and increase productivity with less down time thanks to superior charge/discharge efficiency.
Suitable for use in a wider range of applications where ambient temperature is unusually high: up to +60°C.
Lithium batteries provide more Wh/Kg while also being up to 1/3 the weight of its SLA equivalent.
