Do you use them with a KICk?
The Panasonic & Orbtronic batteries, you mentioned in your previous post, should work fine with a kick. Just check to see weather or not the Kick works with flat top batteries. If not, you'll want to make sure to get the batteries with nipple tops.
Bear in mind that you'll need the optional extension tube if you want to use them together with the ELA.
Is there a particular concern you have?
