RePhone Geo battery dimensions

Could someone do me a favour and measure up the battery that comes with the Geo kit for me?
Just trying to get an idea of what size enclosure I’ll need or if I should find a different sized battery.

Harry,
I have the exact dimensions of the RePhone kit create battery at home (can post them later) but roughly is 50x50x3 millimetres.

Regards!

Awesome thanks for that.
