O.K. looks like the new 4600 cell is about 72 grams each on my scale and the older 4200 is about 70 grams on my scale.

The #'s did not show up in the pic but it says 433grams, I'm guessing there is a gram of glue?

Add about 2 grams per battery bar when it is complete as well so about 445~ grams when complete.
