you might be able to get them, try out hardware stores.
Long ago, there was, i really can't remember the name, probably 14 or so years ago.
It was a bright yellow colour. All the rechargables in its product range were yellow.
IF you want the sag, u might wanna try the voodoo lab's power supply. it has 2 SAG plugs that u can tailor to a lil lower voltage.
the others can just use the other dedicated power supply.
