1. Summary

A European outdoor equipment brand came to VATS Battery with a simple but urgent problem: its new portable device ran out of power too fast. They needed a custom lithium polymer pouch cell with high discharge capability, full CE and UN38.3 documentation, small-batch flexibility, and a short lead time. VATS Battery designed a custom lipo battery cell, delivered certified samples and the first batch in four weeks, and helped the customer bring a better product to market on schedule.

2. Client Background

The customer is a European outdoor equipment manufacturer. They design portable, field-ready devices for professional and outdoor use. Battery performance sits at the core of their product: runtime, reliability, and safe transport all depend on the cell inside. They had been using standard off-the-shelf batteries, but their new model demanded more from the pack.

3. Client Challenge

Their existing battery could not deliver enough sustained current for the new device's peak load. Runtime fell short of the specification, and the unit overheated under heavy use. On top of the technical gap, the project carried two hard constraints. First, compliance: the battery had to meet CE and UN38.3 requirements, with supporting documents ready for EU import. Second, speed and flexibility: they needed a small initial quantity and a short lead time to protect their launch date. Off-the-shelf cells could not satisfy all three at once.

4. Our Solution

VATS Battery proposed a custom lithium polymer pouch cell built to the customer's form factor and discharge profile. Our engineers matched the cell chemistry and internal construction to the device's peak load, so the pack could support sustained high-rate discharge without overheating. Because the customer needed a custom lipo battery cell, not a standard model, we handled the full customization: capacity, dimensions, and connector layout were all set to their design. We also prepared the complete certification package, CE and UN38.3 documentation included, so the customer could import and sell in the EU without extra compliance work. Small-batch was not a problem. We scheduled a limited first run at a level a new product launch could support, with a clear path to scale as orders grew.

5. Project Delivery

• Samples delivered in four weeks, together with the first batch.
• Full CE and UN38.3 certification documents issued for the customized cell.
• High-rate discharge performance verified against the customer's device before shipment.
• Batch production started immediately after sample approval; goods shipped to Europe on schedule.

6. Project Result

The customer's new outdoor device met its runtime specification. The custom lithium polymer pouch cell delivered stable power under peak load, and the overheating issue was resolved. Because we finished on time, the customer kept their planned launch date. They have since ordered repeat batches and are now evaluating the same custom lipo battery cell for two more products in their line.

7. Conclusion

Custom lithium polymer pouch cell development does not have to mean long lead times or huge minimums. If your product needs high discharge, certified cells, and a short timeline, talk to VATS Battery. We design custom lipo battery cells and deliver samples and small batches fast, so you can bring a better product to market on time.
