菲律宾采购需求：电池管理系统、BMS电池、BMS模块、锂BMS、BMS锂电池、Lifepo4 BMS

I am reaching out to request the firmware secure code necessary for updating the software on my Battery Management System. The specific details of the system are a smart active balance BMS designed for 4-8 series configurations, featuring a robust discharge and charge current capacity. Additionally, it is equipped with a balance current of 1A. It would be great if you could provide the code at your earliest convenience, as this update is essential for the optimal performance of the system. You can refer to the specifications associated with the unit from DONGUAN DALY ELECTRONICS L.TD. for any further clarifications needed. Appreciate your assistance on this!
