I have a 0.25A@14V solar panel that I want to use to float charge two 12V flooded lead-acid deep-cycle batteries (boat). I would like to use a current-splitter to feed the two batteries so that if either battery were to develop a shorted cell, the other battery still gets half the available solar current.
I have used a "battery isolator" consisting of two diodes connected common anode, with the two cathodes connected to the positive pole of the two batteries, respectively. However, that just means that one battery can hog all the available current. In the event the battery goes bad, it hogs all the current and the other (good) battery gets none.
The current splitter circuit should have less than 1V drop between the solar panel input and the positive pole of the battery it is connected to.
