The factory has a production workshop of over 5,000 square meters on two floors, along with six automated battery production lines and mobile power supply assembly lines. All production workshops utilize advanced dust-free manufacturing facilities. The factory owns 10 sets of aging equipment, enabling the simultaneous testing of 10,000 finished mobile power supplies for aging conditions.

Before final assembly, the batteries undergo two rigorous tests, and after assembly but before packaging, they pass additional professional aging tests.

Payment method: Due to the low profits of the factory, in order to maintain stable cash flow, we require a 30% deposit before placing an order.

For first-time cooperation with a company having a large order volume, it is recommended to consult the factory first before placing the order and accept inspection by a third-party inspection company.
