I'm working on a project involving 10 volt solar panels charging 12 volt batteries. I'm looking at a voltage booster on ebay, that regulates its output voltage. The problem is that solar cells are current limited which means that if the booster wants more current than the solar panels produce the voltage will drop until the booster can't boost the voltage any more. I'm wondering whether I can modify this booster to regulate the input voltage to the panel's most efficient voltage and boost all of the available power unregulated through a diode into a battery.
My plan is to cut the feedback trace and solder in my own feedback loop coming from the input voltage.
Below are links to the booster and datasheet.
