In addition to adding resistors across each cap. to equalize the voltage. If the caps in question are polorized then you may want to wire the caps + to + then - to -, this sort of creates a non-polorized cap.. I used to do this years ago, works fine but you may see some problems after many quick discharges. Note: be careful experimenting with large electrolitics and reverse charging, when they go its very active, don't inhale the gases. Ric
