I thought originally it was a 4.8V pack (4 cells). Over here a common cordless telephone used the
same pack about 20 years ago, so spares for that (available quite easily) went in my RK05s...

The RK06/RK07 has an 8 cell pack, it's exactly 2 RK05 packs in series.

I can't get one onto the rack sliders on my own if it's fully assembled. I normally remove
the PSU and positioner and then it is quite easy...
