Basically my goal is to find a solution that will utilize solar energy to the max, but limit charge current to under 90mA, but still pull full potential from the sun when it is available. I partially achieved this, but one thing i'm not sure is the behavior of charge controller that still pushes ~20mA into the battery while fully charged at 4.2v. Would not trickle charge do the same to a fully charged battery, except you would have even less control on the voltage?
