Help designing a arduino controlled High current voltage regulator

I completely agree with you and I am willing to do the same..
But please look at my challenge at my last post.
Charging and discharging on the same rail. Discharge to only the controller but also recharge at controlled amp at the same time from the same rail.

I must admit I'm really struggling to understand that last post. I'll read it again in the morning - maybe my brain is getting fatigued! :slightly_smiling_face:
