200pcs customized 25.9V173Ah NMC battery packs to Switzerland

A regular customer from Switzerland has placed a new order for 200 units of customized 25.9V 173Ah NMC battery packs. The battery packs are designed for autonomous weeding and data collection robots deployed across Europe.

This latest order represents an upgrade in both cell chemistry and capacity. The 25.9V 173Ah battery pack is built using a 7S1P configuration of 3.6V 173Ah NMC cells, which offer higher energy density compared to previous solutions.

The customer’s journey with our factory began in January 2024, when they placed an initial test order for 128 units of CALB L160F100 3.2V 100Ah LiFePO₄ batteries. After the test phase was successfully completed, the customer returned in October 2024 with a larger order for 776 units of the same CALB L160F100 LiFePO₄ batteries.

For this new project, the customer opted to transition to NMC chemistry to achieve higher energy density and improved capacity, meeting the performance requirements of their robotic applications.

The shipment of the 200 battery packs was delivered in two batches. Half were shipped by sea before the Spring Festival, while the remaining units were shipped by air in March to ensure timely delivery.

To support the customer’s import process, we provided both the Certificate of Origin and the Certificate of Original, which are used under the China-Switzerland Free Trade Agreement (FTA) to prove production origin and reduce import duties.
