Sources for battery packs that use ultrasonic wire bonding?

Hi,

Is anyone aware of any other vendors that produce battery packs that utilize ultrasonic wire bonding? Luna is the only one I've come across that does it.

EM3EV brought the first ebike battery with individually fused cells to market at the Taipei Bike Show a couple of years ago. EM3ev cells are fused with diecut nickel bussing and so have no separate bonding step for added fuse wires.

Check them out if you want safe cell-level fusing and don't demand the particular wire-bonded fusing technology.
