WBjr with big array and small battery

With solar panels historically cheap, and batteries historically expensive, it may make sense in some systems (with large daytime loads and small loads at night) to have too small a battery for the array.  Fortunately the Classic can limit its output to protect the battery. 

Unfortunately, this current limit applies to the entire output of the Classic, not just the output that goes to the battery.

Is it possible with the WBjr to program the Classic to limit its current to the battery, while allowing full output for loads?  It would have to limit its current dynamically as the loads change.

AND,  following along in the same  line,  would like to see an EQ battery current limit,  using battery current data from the WBjr.

There will always be the question about the voltage at which this current limit begins to be applied,  which may make this function more difficult to design and program.

Possibly,  EQ could have two voltage settings:  the first voltage might be the point at which the current limit begins to be applied,   and the second voltage the desired voltage at which voltage regulation begins -- the traditional EQ voltage setting   ...
yea,  always want too much.   FWIW,  Thanks,      Vic

If the current can be limited from the WB Jr. information, it would work in any charge mode.  Including EQ.

This will be in there hopefully not too long.
