How is the super-capacity 12V400AH lithium-ion battery made? 丨The whole process

Hi, everybody! This is Guangzhou TYCORUN Energy Co., Ltd. Today I will introduce to you our ultra-large capacity 12V400AH lithium-ion battery. Before making this video, many people were curious about how it was produced. Today I will tell you in detail how our super-capacity lithium-ion battery is produced. If you still have some questions after watching the video, you can take a look at our detailed introduction to the video. I believe there should be the answers you want to know.
Here are a few steps to assemble the battery:

  • 1. Battery capacity
  • 2. Battery spot welding, parallel connection
  • 3. Battery cell insulation assembly, tin wire welding
  • 4. Install the BMS board
  • 5. Monitor BMS and package
  • 6. Insulation sponge pad and battery box package
  • 7. Super capacity after drying 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 12.8V400AH Li-ion battery:

    Eco-Friendly: Green energy with no toxic chemical material
    Super Long Life: 2000-5000 cycles, 10-year service life
    Rated capacity size:5120Wh
    Battery weight: Approx. 48.5Kg
    High Safety and Stability: Grade A cells with built-in BMS(Battery Manage System) protection from over-charge, over-discharge, over-load, over-heating, short circuit. Low self-discharge rate 3%
    Wide Working Temperature: Charging Temperature 0℃-55℃; Discharging Temperature -20℃-60℃
    Lightweight, Easy to Install and Fast Charging: Great replacement of SLA/VRLA(lead acid batteries), with 2X Load Power,8X Cycle Life,1/3 Weight,1/5 Charging Time

    Application scenarios

    12V 400AH Home Photovoltaic Energy Storage Battery

    As battery technology and solar photovoltaic system technology become more and more mature, people begin to install and configure solar photovoltaic systems at home. In this way, the energy of the sun can be used to generate electricity, which saves energy and saves a lot of electricity. The electricity stored in our 12V 400AH home photovoltaic energy storage battery is enough to support the normal life of a family for a day, and it is a good helper for the home.

    12V 400AH lithium battery for backup power in company network room
    The power supply of the company's network computer room is the embodiment of high-level backup power supply. He is enough to cope with the instability of the voltage in the company's daily office. Large energy storage capacity and provide continuous and stable current, so there is no need to worry about important files damaged because there is no backup. Solve our office anxiety.

    Our company Tycorun ( has a professional and experienced team of technical experts and top-notch product designers. We have been winning great achievements on energy development. Products are exported to Europe, North America, South America, Africa.
    Our Tycorun Lithium Batteries series is a series that specifically replaces the old lead-acid batteries. Based on the lithium battery with the high characteristics of energy density, 1/3 light weight, environmental protection, green energy and others. It maximizes its advantages and achieves the global "carbon peak" and "carbon neutral" goal. Our LiFePO4 battery will contribute more to this goal.
