Dear Jetijs,

Thought to share an observation of mine to you. I had found out before that if I connect a parallel capacitor (The capacitance is not very much important, 330uF for example) to my output battery it would increase the recovery to the battery. The capacitor seems to be able to "catch" more of the recovery and redirect it to the battery. The internal Impedance of the battery is the main cause of this effect I suppose. I suggest you using a capacitor parallel to your battery and comparing the results. Good luck with your marvelous work!
