Lee you sure don't know how to toot your own horn . Of all the battery equalizers out there yours is by far the best idea I have seen . You equalize both charging and discharging , and not just to the bat next door either. You should be selling the thing . I'd like to make them and sell them and give you a cut for all your work in designing it . look at the website Roger Stockton set up for the Balancer? See <http://www.geocities.com/sorefeets/balancerland/index.htm> Do you have a file to send off to get pc boards made?
