While we do not sell these pouches directly, we have tested 2 kinds and you can find either of them below:
AWP Bag
This is the original bag we had used from the start:
Lowes (Click Here)
However, the AWP bag is being phased out and replaced with a Kobalt alternative.  That bag can be found here:
Lowes (CLick Here)
BucketBoss Bag:
Home Depot (Click Here)
Amazon (Click Here)
Both bags work very well and are compatible with LynkSpyder and all of the batteries we test.  We primarily use the BucketBoss bag because of the color.  We find this color keeps the battery less hot than the Lowe's bag, which is black (black material and sunlight generally mean more heat).  However, we still keep the Lowe's bag on our list because they can generally be picked up locally at any Lowe's store in your area and we have used them for years without any major issues.
