In Electric flying there are a number of simple tricks that can really make a difference in performance. One of these is to charge the Ni-Cd pack until it peaks (or gets warm) on the fast charger, and then put it on trickle charge overnight before you go flying. One charger works well to quick-charge several packs, but how do you trickle charge multiple packs for a day's flying? You build The Ni-Cd Topper, a multiple-output trickle charger. By simply adding components, as many as 10 charging outputs are possible.
