Safety is critical in robotics, especially for custom lithium battery packs. You must meet global and industry-specific standards before mass production. The table below lists key certifications:

You should always verify that your custom lithium battery meets these standards to ensure safe operation in robotics, medical, and industrial environments.

Part 2: Prototyping & 3D Printing

2.1 Rapid Prototyping

You can accelerate your custom lithium battery development by using rapid prototyping. This approach lets you create a prototype quickly, so you can test fit, function, and safety before moving to mass production. In robotics, medical devices, and industrial automation, you need to see how your battery pack performs in real-world conditions. Rapid prototyping helps you identify design flaws early. You can make changes to the prototype without high costs or long delays. This process reduces risk and improves your final battery design.

2.2 3D Printing in Battery Design

3D printing has transformed how you design and build battery enclosures. You can create complex shapes that traditional manufacturing cannot achieve. This flexibility is valuable for robotics and security systems, where space and weight matter. You can also iterate designs faster, which means you get a better prototype in less time. However, you should know the limitations of 3D printing:

You should select materials that match the thermal and electrical needs of your lithium battery chemistry, such as LiFePO4 or NMC, especially for medical and industrial applications.

2.3 Initial Testing

After you print your prototype, you need to test it in small batches. This step checks if your lithium battery pack meets safety and performance goals. You can evaluate thermal management, enclosure fit, and electrical connections. Testing in real application scenarios, like robotics or infrastructure, gives you feedback to refine your prototype. You should repeat this process until your battery meets all requirements.

Tip: Small batch testing helps you avoid costly mistakes before mass production.

Part 3: Validation & Small Batch Testing

3.1 Safety Validation

You need to ensure safety and reliability before moving your lithium battery pack into mass production. Safety validation starts with quality assurance during both development and production. After assembly, you must handle and store the battery correctly to prevent damage. When your end customer receives the device, they should check for cell leakage and monitor temperature.

Common safety validation procedures include:
