Well.....it does charge 11v lipos which are higher then 9.6,but the issue may come down to what "type" of batteries this charger in particular chargers. I know its designed to charge nicd's,nimh's,and lipos...but,the battery your looking to charge is a lead battery I believe which I dont believe would fall into any of those catagories,so that is likely the major issue here not?
And Excellent question by the way!!! I have all this equipment you speak of,so it made me think about it. And I just noticed you mentioned some of this already after I posted....
