Find out in a minute how to make a 12V 18Ah lithium battery for lawn mowers

Hi, everybody! This Guangzhou Tycorun energy co ltd.
Today I will introduce you how the 12.8v 18AH lithium battery is assembled.
Several steps to assemble the battery:

1. Weld the nickel sheet:

Firslyt, the nickel piece is used to connect the battery cell in series and parallel through welding, and then the data acquisition wire is used to weld the positive and negative electrodes of the battery pack.

2. Welding of BMS:

Secondly,Fix a BMS that monitors the battery running status in real time and protects the battery string from overcharging, discharging, overcurrent, and overtemperature on the battery pack,Then weld the positive and negative battery string wires to the BMS.

3. Pass the BMS connection test:

Connect the data acquisition line port to the BMS to test the battery voltage and resistance, and seal the exposed wiring with insulation and waterproof adhesive after the test.  

4. Battery packing and drying:

Finally, the battery pack is fixed with waterproof glue in the battery box.After three hours of drying, a battery

5. Super cycle times:

that can be recycled more than 2,000 times is assembled.

Application scenarios


Did you expect such a moment? When you use the blood pressure meter, you suddenly lose power and can’t continue the diagnosis and treatment? For the power supply of medical equipment, we must achieve uninterrupted power supply. Even if the power is off, at least the diagnosis can be completed. For such demand, another use of 12V 18Ah lithium battery has been spawned as an emergency backup power for medical equipment. When you encounter a power failure, our lithium-ion battery is your most trusted partner at the moment.


Spring is the season of recovery, and weeds are no exception. But can you accept that there are more weeds in your yard than flowers? the answer is negative. At this moment, the electric lawn mower will be your best choice. The lawn mower with a 12V 18Ah lithium-ion battery can provide you with strong support. Compared with ordinary battery lawn mowers, lithium battery lawn mowers can provide 3 times the use time. Moreover, it is light in weight and small in size, which does not bring too much burden to gardeners and can enjoy the joy of working in the yard. And this is exactly what we want to provide you.
