Quickly learn how to make 12V 50Ah lithium battery丨The whole process

Hi, everybody! This is Guangzhou TYCORUN Energy Co., Ltd. Welcome to watch our video today. In the video, we introduce the production process of 12V50AH lithium-ion battery in detail, and strive to let everyone understand how the lithium-ion battery is made in the shortest time. For what you don't understand, you can read our article below, you can further understand the whole process of battery production.
Here are a few steps to assemble the battery:

1. Battery capacity

After got the cell batteries, those batteries have done of capacity grading.

2. Battery spot welding, parallel connection

First of all,using UV machine automatic to connect the cells in parallel by spot welding.

3. Battery cell insulation assembly, tin wire 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.

4. Install the BMS board

Then fix a BMS board on the top of battery pack with insulation paper that can collect data such as battery voltage and capacity.

5. Monitor BMS and package

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.

6. Insulation sponge pad and battery box package

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.

7. Super capacity after drying the battery

After 3 hours of drying, a battery that can be recycled for more than 2000 times is finished.

Below are the details of our 12.8V50AH Li-ion battery：

Application scenarios

12V 50AH LITHIUM BATTERY FOR VENTILATORS

Ventilators are widely used during the epidemic. For people who are dying, ventilators are the most important epidemic to save lives. But have you ever thought about it. When the mains power is interrupted, without the support of direct current, the ventilator will lose its function. Therefore, the lithium battery can provide backup power for the ventilator. In an emergency, the high current discharge of the lithium battery can easily drive the ventilator and provide stable energy for a long time.
