A123 Battery Packs

With the new Lithium craze kicking in, I purchased myself some Dewalt batteries off ebay that have the A123 System cells. I also purchased these groovy ‘MEC’ solderless pack assembly kits that allow you to assemble the cells into batteries packs relatively fast.

The A123 cells come with a cardboard cover from Dewalt, it’s recommended to remove that and shrink wrap the cells to allow heat dissipate.

I don’t have a heat gun or a hair dryer… so…

Perfectly toasted!

6 cells are loaded into the ‘shotgun’ tubing

The end caps are them spread open and pressed on.

Connecting the two end caps with a pair of tensioning rods and a completed pack is made.
