The individual cells that we use in our battery packs are sourced from well-known brands such as Panasonic, LG, Samsung, etc. from their official dealers or their own factory.

Then our engineers develop a prototype of your battery pack.

This prototype passes through many tests with the help of testing machines, such as the Aging testing machine, drop testing machine, waterproof testing machine, etc.

After you are satisfied with the specifications of our prototype, our production team will proceed with the bulk production of your custom battery pack.

Our expert technicians will assemble each individual cell to form a battery pack. And then they will cover the assembled batteries with a heat shrink and enclose them in suitable housing.

At TLH we use automated welding machines to ensure the efficiency of the manufacturing process and the quality of the products.

You can design the housing of the battery pack or if you have confusion regarding it, you can contact us, and we will design the battery housing for you.

5. What are the Certificates for Your Custom Battery Pack that You Need?

 

IEC 62133, UN38.3, ISO 9001:2015, CE certificate, UL 2054 certificate.

Safety certificates are imperative for the transportation and application of a custom battery pack.

We have briefly explained the most important certificates that you need for your custom battery pack below:

IEC 62133

IEC 62133 is the most important certificate when it comes to importing Li-ion custom battery packs. This certification involves certain tests for the Li-ion batteries.

These tests include external short circuit tests for individual cells and the battery pack, free-fall tests, overcharging tests, and mechanical tests to name a few.

UN38.3

The UN38.3 is another very important certificate that your custom battery needs to have.

The UN formulated this standard for the safe transportation of hazardous goods.

This certification requires many tests including altitude simulation for air-travel safety, thermal, vibration, and shock tests among a variety of other tests.

Therefore, if you want your custom battery pack to reach you safely by air, sea or rail, or road, it needs to have a UN38.3 certificate.

ISO 9001:2015

ISO 9001:2015 is the latest standard from the ISO 9000 standard family.

ISO 9001 is the standard, that if the product meets, it can be rendered safe for general public use. It helps the manufacturers meet their Quality Management System requirements and consistently develop products that meet their customer’s demands.

If your battery pack is ISO 9001:2015 certified, be rest assured that it competes with all other battery packs in the market in terms of quality and performance.

CE Certificate

CE symbol is representative of European Conformity.

On your battery pack, CE represents that its specifications align with the standards set by the European Union.

UL 2054 Standard

The UL 2054 is a standard that vouches for the safety associated with your battery pack.

This standard might be the most important if you are importing your battery pack for a project based in the US.

This standard requires your battery packs to pass several tough tests, such as the Construction Assembly test, Abnormal Charging Test, Drop test, and many others.

Our team at THL can help you get these certifications for your products to ensure that your custom battery packs reach you safely.

6. How to Choose a Professional Custom Battery Pack Manufacturer?

Get on the internet and look for reviews from previous customers of a battery pack manufacturer. This will help you in choosing the right custom battery pack manufacturer.

Here are a few more tips to help you choose a professional custom battery pack manufacturer:

Pick a custom battery pack manufacturer that has over 10 years of experience in the Li-ion battery industry.

The manufacturer must have licensed personnel and highly experienced engineers who have worked in Lithium-ion battery manufacturing.

Before deciding on a manufacturer, it is best to choose a manufacturer that has a strong QA team.

Your professional manufacturer must provide batteries that can secure all the necessary battery certifications such as IEC 62133, UN38.3, and others.

A battery pack manufacturer must promise proper packing and efficient shipping and offer at least 12 months warranty for their product.

It is best if you settle on a manufacturer who has teams to assist you all the time during the design and manufacturing process of your product.

We recommend you pick a custom battery pack manufacturer that has service centers in your local area. In this way, they can provide you with quick technical support.

7. How to Verify your Custom Battery Project Quality System Control?

By inquiring about all the tests that the manufacturer will perform to check the quality of your custom battery pack.

To meet international standards, battery packs need to pass a variety of different tests.

These tests include battery aging test, waterproof test, drop test, charger test, and BMS test to check charge and discharge current.

We recommend that you ask your manufacturer for all the tests that they perform on their battery packs.

Moreover, check for the international standards that the custom battery pack manufacturer claims that their products meet.

This will give you a comprehensive idea about the quality system control of your custom battery project.

8. How to Get a Suitable Custom Battery Pack for Your Project?

Check the cell brand, know your required battery pack production quantity, and go over your custom battery pack design.

The capability of a battery pack to meet your requirements depends upon its cell’s brand.

If you need a battery pack for heavy-duty applications, it’s best that you go for a custom battery pack that utilizes cells from top brands such as Samsung and Panasonic, etc.

Knowing your required product quantity is important because it helps you decide on a MOQ.

Assessing your design is imperative to ensure that the product that you receive at the end of the manufacturing process meets your requirements and fits your application.

We also recommend that you pre-determine the operating conditions in which your battery has to perform and its specific application.

Then, check for the battery’s voltage, charge rate, energy density, operating temperature range, safety, and life cycle.
