Here is Guangzhou Tycorun energy co ltd.The leading supplier and manufacturers of lithium ion batteries situated in China
Today I am going to introduce to you how to make a 12v 200ah lithium ion battery .
After got the lithium cell batteries, those batteries have done of capacity grading. First of all,using UV machine automatic to connect the lithium cells in parallel by spot welding.
The lithium battery cells which connected in parallel are separated by insulating paper and assembled together. Welded the lithium 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 12v 200ah lithium battery pack with insulation paper that can collect data such as battery voltage and capacity.
The BMS protection board can monitor the 12v 200ah lithium battery pack status in every time, and provide protections such as over-charge, over-discharge, over-current, and over-temperature when necessary. BMS is equipped with Bluetooth function, and you can see the information and status of the battery in the mobile app To weld the positive and negative terminals of the battery pack to the BMS board.
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 12v 200ah lithium battery pack. After 3 hours of drying, a battery that can be recycled for more than 2000 times is finished.
