[Elecraft] KX2 - Dimension of the KXBT2 Li_Ion pack?

[Stephan]

Dear KX2-users,

I would like to know the dimension of the Li-Ion package: Height, width and length?
How long is the power cable inclusive 2.1mm plug?
As well I’am interested about the dimension of the space inside the KX2, which is reserved for the KXBT2 Lithium-ion Battery Pack.

As far as I know, the package (11V, 2.6Ah) consists of three Lithium-Ion 18650 cylindrical cells with integrated security (PCB).

I’am intend to order in Germany a pack of three 18650 cells with a capacity of 3400mA. To tell the dealer the specification, I need the dimension of the original KXBT2.

thanks,
Stephan, DD6DO
