When I talked to Josh at MaxAmps today he said the new B44 packs are currently being tested. The only thing he knew was that the new packs are being made with new 2200mah cells. The shape of the new cells is the same as if it where a sub C pack. The only thing he was saying is that they will be offering a 4400 and a 6600 pack for the B44. He thought around Christmas time though.
