Support battery pack designs from concept to launch, and identify tiers to support mechanical solutions and automation needs.

E-Fill Solutions

Traditional E-fill was a crimp after the fill

Prismatic and Some 4680 providers put a port hole in the lid for the electrolyte fill

After filling, you’ll need a laser-welded plug or steel fastener to plug your hole

Our new option beats all existing ones
