Quality control about lipo battery
We are committed to providing customers with high quality battery, from material selection to production, strict control of each production process.
1 Materials of LiPo Battery
The graphite, pure water & lithium cobalt oxide we purchase from quality material suppliers are put into a vacuum high-speed stirring machine more than 12 hours to ensure that the density of the entire cylinder of raw materials.
2 Coating of LiPo Battery
High-precision thermostatic coating machine and laser keep the same thickness tolerance less than 0.5mm.
3 Sheet of Li Po Battery
Precision automatic roll machine to ensure the height of the pole piece of the same thickness; ultrasonic welding makes pole piece and perfect pole combination, welding firm, low resistance. Hundreds of points knife mold, so you no longer need to open a small batch of the mold trouble.
4 Wrapping of LiPo Battery
We bought the aluminum-plastic film from Japan without wrinkles, rupture. The automatic winding machine makes the consistency of the core volume. The high-temperature sealing machine seals the edge of the LiPo battery to insulate air moisture.
5 Assembling of LiPo Battery
The point inspection for internal resistance & voltage before assembling PCM, wires & connector. We do another testing again for the above items after collecting.
