With the continuous progress of the lithium energy industry, lithium battery, as a high energy density storage medium,
attracts more people's attention. Guangdong Jiawei New Energy Technology Co., LTD. (For short, Jiawei Xinneng),
especially 18650 lithium battery, due to its excellent performance and wide application,
has become the new favorite of DIY enthusiasts. In the New Year approaching, we might as well try a 18650 lithium battery DIY project,
can not only experience the charm of technology, but also to improve the hands-on ability.
The 18650 Lithium-ion battery is a cylindrical lithium-ion battery with a diameter of 18mm and a height of 65mm.
It has the advantages of high energy density, long cycle life and low self-discharge rate,
and is widely used in notebook computers, electric vehicles, LED lamps and other equipment.
Due to its standardized specifications, the 18650 battery became the best choice for the DIY project.
一、What does the DIY project prepare for?
Before you begin the DIY, you need to prepare the following materials and tools:
1. 18650 Lithium battery: It is recommended to choose reliable and high quality batteries to ensure safety and performance.
For example, like EVE, Tianpeng, Giant, Samsung, SONY, our suppliers have been cooperating,
choosing 18650 lithium battery to look for Jiawei new energy 3C quality certification.
2. Battery bracket: used for fixing the battery, convenient for connection and replacement.
3. Protection board: to prevent overcharge, overdischarge and short circuit, to ensure the safety of use.
4. Welding tools: such as electric soldering iron, solder, used to connect the battery and the circuit part.
5. Multi-purpose meter: used to test the voltage and current to ensure that the circuit is normal.
二、 What is the DIY process?
1. Design circuit: design the circuit diagram according to the requirements, which can be a simple LED lighting circuit
or USB power supply module. Ensure that the current and voltage match.
2. Battery connection: Install the 18650 battery into the battery bracket, and pay attention to the correct connection of
the positive and negative poles.
3. Welded protective plate: weld the protective plate to the positive and negative electrode of the battery to improve safety.
4. Assembled circuit: weld and connect the components together according to the designed circuit diagram.
Ensure that the connection is firm, no short circuit risk.
5. Test: Use a multi-purpose meter to check whether the circuit is normal, to ensure that the battery can provide a stable voltage and current.
三、 What are the safety precautions?
While DIY projects are fun, safety always comes first. Be sure to follow the following safety guidelines:
Avoid short circuit: During the operation, ensure that the positive and negative poles are not in direct contact.
Temperature control: the welding should be completed quickly to avoid damage to the battery due to overheating.
Use protective equipment: wear protective glasses and gloves to avoid accidental injuries.
四、What is the meaning of the project?
Through this DIY project, you can not only have a deep understanding of how the 18650 lithium battery works,
but also improve your hands-on skills and problem-solving skills. In addition, such projects are also suitable for parent-child activities
to enhance the interaction and cooperation among family members.
In the New Year approaching, a 18650 lithium battery DIY project is a good choice.
It can not only let you experience the shake of technology, but also can bring a sense of achievement and happiness.
I hope everyone can have the courage to try new challenges and explore more unknown areas in the New Year!
