The Challenge
Motor startup surges caused voltage droop on generic cells, leading to stalling mid-cut.
Our Approach
EPT matched chemistry, PCM, and mechanical design to the device duty cycle, then ran safety and lifecycle testing through our CNAS-accredited lab.
Results
The client signed off after DVT and transferred volume production to EPT manufacturing lines.
