Hydrimax batteries

[Chris Moon]

Hi Matt:
    It's kind of strange.  I know that Hydrimax is a Panasonic cell 
"name", but the pack says on the outside "Genuine Sanyo Cells".  Sure 
enough, inside of a Hydrimax pack are Sanyo cells. I really had no issue 
with the way the packs performed with the Sanyo cells, but I think the 
construction and danger of a cut lead and lost plane makes them unsafe. 
  Oh well, at least there are plenty of good options for battery packs.  
I  wanted to make sure anyone who is running the Hydrimax packs check 
for cut leads before it's too late.
