Our Process

At BSLBATT, every product begins with a needs-based assessment where we see an opportunity to fill a power shortcoming or solve a problem with a LiFePO4 battery. We find this information through feedback from customers, what our dealers and distributors are telling us, and what we learn through experience in our own lives. From there we thoroughly explore the technical requirements of the application. What voltage is required and how long does the battery need to provide energy? How frequently will the battery be used? How deeply will it be discharged each use? What equipment will the battery power? Does the battery need to communicate with the devices it will power? Why are LiFePo4 batteries being considered? What are the key success factors that define a favorable result? Once we have all the technical details the factory builds prototypes that are thoroughly tested by not only our Dongguan engineering teams but are further validated through on-site beta testing.
