I tried a 470 in parallel and the min. voltage came down to 3.6 or so. This
did not seem to help much. 20:00 here, will try and experiment tomorrow.
A schematic would help to understand this. Any available ?
There seems to be more trimpots and a couple of buttons the functions
I have no clue about.
