Precision CNC Machined Stainless Steel Battery Clamp ASTM A967 Passivation BESS Energy Storage
Product Description
This precision CNC machined stainless steel 304 battery clamp is designed for Battery Energy Storage System (BESS) modules. Featuring ASTM A967 passivation and precision spring force control (5-50N), the clamp ensures consistent contact pressure on battery cells during thermal cycling. The 304 stainless steel construction provides excellent corrosion resistance in outdoor BESS cabinet environments. Each clamp is 100% spring force tested.
As a leading CNC turning manufacturer with over 15 years of precision machining experience, we produce Precision CNC Machined Stainless Steel...

Frequently Asked Questions
Q: Why is spring force control important for battery clamps?
A: Consistent spring force ensures uniform pressure on battery cells, preventing swelling, maintaining electrical contact, and extending cycle life. Our clamps are calibrated to ±5% of target force.
Q: What is ASTM A967 passivation?
A: ASTM A967 is the standard specification for chemical passivation of stainless steel. It removes surface iron contamination and enhances the natural chromium oxide layer for superior corrosion resistance.
Q: Can you customize clamp dimensions and force?
A: Yes, we design custom clamps based on your cell dimensions, target clamping force, and mounting configuration. DFM analysis is provided free of charge.
