That seems pretty high to me; if I remember to, I'll go check my deathbox voltages tomorrow, but after a few charge/leakdown cycles they pretty much stopped draining themselves a bunch. Is your balancing circuit just a set of resistors and diodes? That might be a cause right there; I have nothing on mine right now.
