I had not noticed.  But, since you mentioned them I see they are a direct competitor for Electrovaya.  The make similar battery packs for materials handling and airport equipment.  One of the things I see is they do not own the cell production.  This could be s supply chain issue.  Also they will have trouble competeing against Electrovaya's "Best Battery in the Market" cells for cycle life and safety.

I did notice another 18% drop in price again today.
