After got the cell batteries, those batteries have done of capacity grading. First of all,using UV machine automatic to connect the cells in parallel by spot welding.
The battery cells which connected in parallel are separated by insulating paper and assembled together. Welded the battery with the data collection line together and then weld the positive and negative wires by solder wire in turn.
Then fix a BMS board on the top of battery pack with insulation paper that can collect data such as battery voltage and capacity.
The BMS protection board can monitor the battery status in every time, and provide protections such as over-charge, over-discharge, over-current, and over-temperature when necessary.
To connect the data collection line to the BMS board and then test the voltage and internal resistance.
After testing, use insulating waterproof glue to seal the exposed wires.
Then paste the buffer insulation sponge on the bottom and put it into the ABS box, and connect the positive and negative wires to the positive and negative ports of the box cover.
Then inject waterproof glue into the space around the box to fix the battery pack. After 3 hours of drying, a battery that can be recycled for more than 2000 times is finished.
