I hope you don't mind namuna but I thought I'ld post a pic comparison of the 210s I got.
As you all can see they are huge. the guy I ordered from said they were slightly bigger than a stock zip cell. I wrote him a couple of love notes and he refunded my money and let me keep the cells.
Namuna did some exacting measurements in the bit forums that everybody should look at before ordering bats.
Namuna, where did you get that 160mah battery? It looks the same as a Zipzap battery, so did you get it at Radioshack? Is it an item that they will probably have in stock?
