How is the 12V 100ah smart lithium-ion battery with Bluetooth BMS made?

Hi, everybody! This is Guangzhou TYCORUN Energy Co., Ltd. Welcome to watch this video. Today we will introduce the whole production process of our popular product 12V 100ah smart lithium-ion battery with Bluetooth BMS. It introduces in great detail how our battery has been transformed from an initial cell into a complete product step by step. In the shortest time, express the most important content. There is also a very detailed text explanation below the video, so that you can quickly understand how the battery is produced step by step.
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

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.

6.BMS board is equipped with bluetooth function

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.

7. Insulation sponge pad and battery box package

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.

8. 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 12.8V100AH Li-ion battery:

Application scenarios


When you start to use pv solar power system, your house becomes more fashionable and modern than before. Presumably your neighbors have already cast envy in their eyes. And when the 12V 100Ah smart lithium battery appears, your home solar system will play a greater role. Excellent discharge current and strong energy storage capacity allow your battery to store more energy during the day. At night, you can even use this energy until the early morning of the next day.

When you own an RV and you’re trying to have a long travel, you will definitely encounter a problem of insufficient power supply. Of course you can use gasoline or diesel to convert energy, but no one can refuse a more cost-effective and greener way, right? And all this is due to our 12V 100ah smart LiFePO4 battery. It can fully store the energy from the sun while you are driving. When night falls, it will all be dedicated to make you spend an unforgettable night. When the sun rises the next day, it can continue to store energy for you, day after day, year after year.

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.
