[Elecraft] K2 internal battery

[inventor61 .]

I was asked several times on private messages for this information.
Note:  I am not affiliated with the supplier in any way.

The discussion was for a custom replacement for the 2.9 Ampere-hour gel
cell used in the Elecraft KBT2.

The replacement suggested by me is a rechargeable 4.5 Ampere-hour LiFePO4
pack.
It fits where the gel cell does, in the Elecraft custom internal bracket.
It is almost exactly half the weight.
