A better solution would be to implement the proportional control, so I will probably wait until I have my master built before I do anything.
It might work better as well if we gain that extra 20mv of resolution using the new formula.
The present Master code has all the proportional control REM'D out at present as I can't test/develop that much until I get my charger and finish my install. I'm pretty sure that will be horribly buggy at present
As we discussed many moons ago I'll be trying to pull the charger voltage down as cells go over MaxV using the same Zivan NG3 mod Cedric used, but controlled by the Master opto isolated output, which will ramp up the opto drive power as the cell voltage rises.
The AbsMaxV setting is used/reserved to control the Charger mains relay in case control cannot be maintained (broken/shorted control wire) or a cell has a problem.
Does your charger have an adjustable output voltage pot? Could you hack it like I'm doing?
